PHP 5.6.29 Released

phpinfo

(PHP 4, PHP 5, PHP 7)

phpinfoPHP の設定情報を出力する

説明

bool phpinfo ([ int $what = INFO_ALL ] )

現在の PHP の状態に関する、多くの情報を出力します。出力される情報には、 PHP コンパイルオプションと拡張機能、PHP のバージョン、 サーバー情報と環境(モジュールとしてコンパイルされた場合)、 PHP の環境、OS バージョン情報、パス、構成オプションのマスター およびローカルの値、HTTP ヘッダ、PHP License などがあります。

システムの設定はそれぞれ違うため、実行時設定 や 利用できる 定義済みの変数 を調べるために phpinfo() がよく使われます。

また、phpinfo() には EGPCS (Environment, GET, POST, Cookie, Server) の情報が含まれているため、デバッグツールとしても便利です。

パラメータ

what

以下にあるconstantsビット値をひとつまたは 複数個を加算して、オプションのwhat引数に 渡すことによって出力をカスタマイズできます。 それぞれの定数やビット値をor演算子 で結んで渡すこともできます。

phpinfo() のオプション
名前(定数) 説明
INFO_GENERAL 1 configure オプション、php.ini の場所、ビルド日時、 Web サーバー、オペレーティングシステム等。
INFO_CREDITS 2 PHP クレジット。phpcredits() も参照ください。
INFO_CONFIGURATION 4 ローカルおよびマスタの、現在の PHP ディレクティブの値。 ini_get() も参照ください。
INFO_MODULES 8 ロードされているモジュールと、それぞれの設定。 get_loaded_extensions() も参照ください。
INFO_ENVIRONMENT 16 $_ENV で取得できる環境変数の情報。
INFO_VARIABLES 32 EGPCS(環境変数・GET・POST・クッキー・サーバー変数)から すべての 定義済みの変数を表示します。
INFO_LICENSE 64 PHP ライセンス情報。» ライセンス FAQ も参照ください。
INFO_ALL -1 上記のすべてを表示します。

返り値

成功した場合に TRUE を、失敗した場合に FALSE を返します。

変更履歴

バージョン 説明
5.5.0 ロゴの GUID がデータ URI に置き換わりました。そのため、expose_php をオフにしても phpinfo() の結果には何も影響が出なくなりました。クレジットも、リンクではなく出力に埋め込まれるようになりました。
5.2.2 "Loaded Configuration File" 情報が追加されました。これまでは "Configuration File (php.ini) Path" しかありませんでした。

例1 phpinfo() の例

<?php

// すべての情報を表示します。デフォルトは INFO_ALL です。
phpinfo();

// モジュール情報だけを表示します。
// phpinfo(8) としても同じです。
phpinfo(INFO_MODULES);

?>

注意

注意:

PHP 5.5 より前のバージョンでは、 expose_phpoff の場合、一部の情報は表示されません。 これにはPHPとZendのロゴ、そしてクレジットが含まれます。

注意:

CLI モードを利用している場合、phpinfo() は HTML ではなくプレーンテキストで結果を出力します。

One note on the very useful example by "jon at sitewizard dot ca". 
The following statements:
Statement 1:
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
Statement 2:
$phpinfo[end(array_keys($phpinfo))][] = $match[2];

These two lines will produce the error "Strict Standards:  Only variables should be passed by reference in...".  The root of the error is in the incorrect use of the end() function. The code works but thows the said error.
To address this try using the following statements:

Statement 1 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];

Statement 2 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][] = $match[2];

This fixes the error.
To wrap it all in an example:
<?php
function quick_dev_insights_phpinfo() {
ob_start();
phpinfo(11);
$phpinfo = array('phpinfo' => array());

    if(
preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER)){
        foreach(
$matches as $match){
        if(
strlen($match[1])){
           
$phpinfo[$match[1]] = array();
        }elseif(isset(
$match[3])){
       
$keys1 = array_keys($phpinfo);
       
$phpinfo[end($keys1)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
        }else{
           
$keys1 = array_keys($phpinfo);
           
$phpinfo[end($keys1)][] = $match[2];     
           
        }
       
        }
}

    if(! empty(
$phpinfo)){
        foreach(
$phpinfo as $name => $section) {
            echo
"<h3>$name</h3>\n<table class='wp-list-table widefat fixed pages'>\n";
            foreach(
$section as $key => $val){
                    if(
is_array($val)){
                    echo
"<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
                    }elseif(
is_string($key)){
                    echo
"<tr><td>$key</td><td>$val</td></tr>\n";
                    }else{
                    echo
"<tr><td>$val</td></tr>\n";
                }
            }
        }
            echo
"</table>\n";
        }else{
    echo
"<h3>Sorry, the phpinfo() function is not accessable. Perhaps, it is disabled<a href='http://php.net/manual/en/function.phpinfo.php'>See the documentation.</a></h3>";
    }
}
?>
Frankly, I went thought the trouble of adding this note because the example by "jon at sitewizard dot ca"  is probably the best on the web, and thought it unfortunate that it throws errors. Hope this is useful to someone.

A simple method to style your own phpinfo() output.

<style type="text/css">
#phpinfo {}
#phpinfo pre {}
#phpinfo a:link {}
#phpinfo a:hover {}
#phpinfo table {}
#phpinfo .center {}
#phpinfo .center table {}
#phpinfo .center th {}
#phpinfo td, th {}
#phpinfo h1 {}
#phpinfo h2 {}
#phpinfo .p {}
#phpinfo .e {}
#phpinfo .h {}
#phpinfo .v {}
#phpinfo .vr {}
#phpinfo img {}
#phpinfo hr {}
</style>

<div id="phpinfo">
<?php

ob_start
() ;
phpinfo () ;
$pinfo = ob_get_contents () ;
ob_end_clean () ;

// the name attribute "module_Zend Optimizer" of an anker-tag is not xhtml valide, so replace it with "module_Zend_Optimizer"
echo ( str_replace ( "module_Zend Optimizer", "module_Zend_Optimizer", preg_replace ( '%^.*<body>(.*)</body>.*$%ms', '$1', $pinfo ) ) ) ;

?>
</div>

Embedding phpinfo within your page, that already has style information:

The phpinfo output is wrapped within a <div class='phpinfodisplay'>, and we privatize all the style selectors that phpinfo() creates.

Yes, we cheat on preparing the selector list.

<?php
ob_start
();
phpinfo();

preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);

# $matches [1]; # Style information
# $matches [2]; # Body information

echo "<div class='phpinfodisplay'><style type='text/css'>\n",
   
join( "\n",
       
array_map(
           
create_function(
               
'$i',
               
'return ".phpinfodisplay " . preg_replace( "/,/", ",.phpinfodisplay ", $i );'
               
),
           
preg_split( '/\n/', $matches[1] )
            )
        ),
   
"</style>\n",
   
$matches[2],
   
"\n</div>\n";
?>

Perhaps one day the phpinfo() function will be modified to output such a safe string on its own.

I needed a way to quickly scroll through the phpinfo which is a large list of information. so here it is. In the top there is a list with sections, the new section loaded extensions will hold the links to the anchors of the loaded modules. the section session variables will show the current loaded sessions. It's using Domdocument for manipulation so you should have that loaded:
<?php
ob_start
();
   
$exts = get_loaded_extensions();
   
phpinfo();
   
$phpinfo = ob_get_contents();
   
ob_end_clean();
   
//print $phpinfo;
   
$html_str = $phpinfo;
   
$html = new DOMDocument();
   
$html->loadHTML($html_str);
   
$title = $html->getElementsByTagName("title")->item(0);
   
$title->nodeValue = "PHP Version ".phpversion();
   
$body = $html->getElementsByTagName("body")->item(0);
   
   
$body->setAttribute("style", "background-color:beige;");
   
$table = $body = $html->getElementsByTagName("table")->item(3)->nextSibling;
   
$head  = $html->getElementsByTagName("table")->item(0)->nextSibling;
   
ob_start();
   
?>
    <h2><a name="session_variables">Session variables</a></h2>
    <table border="0" cellpadding="2" width="600">

        }else if(
is_array($value)){
           
$value = '<pre>'.print_r($value, true).'</pre>';

Removes sensitive data like AUTH_USER and AUTH_PASSWORD from the phpinfo output:

<?php
// start output buffering
ob_start();

// send phpinfo content
phpinfo();

// get phpinfo content
$html = ob_get_contents();

// flush the output buffer
ob_end_clean();

// remove auth data
if (isset($_SERVER['AUTH_USER'])) $html = str_replace($_SERVER['AUTH_USER'], '<i>no value</i>', $html);
if (isset(
$_SERVER['AUTH_PASSWORD'])) $html = str_replace($_SERVER['AUTH_PASSWORD'], '<i>no value</i>', $html);

echo
$html;

After reading and trying various functions, I couldn't find one that correctly parses all the configurations, strips any left-over html tag and converts special characters into UTF8 (e.g. &#039; into '), so I created my own by improving on the existing ones:

function phpinfo2array() {
    $entitiesToUtf8 = function($input) {
        // http://php.net/manual/en/function.html-entity-decode.php#104617
        return preg_replace_callback("/(&#[0-9]+;)/", function($m) { return mb_convert_encoding($m[1], "UTF-8", "HTML-ENTITIES"); }, $input);
    };
    $plainText = function($input) use ($entitiesToUtf8) {
        return trim(html_entity_decode($entitiesToUtf8(strip_tags($input))));
    };
    $titlePlainText = function($input) use ($plainText) {
        return '# '.$plainText($input);
    };
   
    ob_start();
    phpinfo(-1);
   
    $phpinfo = array('phpinfo' => array());

    // Strip everything after the <h1>Configuration</h1> tag (other h1's)
    if (!preg_match('#(.*<h1[^>]*>\s*Configuration.*)<h1#s', ob_get_clean(), $matches)) {
        return array();
    }
   
    $input = $matches[1];
    $matches = array();

    if(preg_match_all(
        '#(?:<h2.*?>(?:<a.*?>)?(.*?)(?:<\/a>)?<\/h2>)|'.
        '(?:<tr.*?><t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>)?)?</tr>)#s',
        $input,
        $matches,
        PREG_SET_ORDER
    )) {
        foreach ($matches as $match) {
            $fn = strpos($match[0], '<th') === false ? $plainText : $titlePlainText;
            if (strlen($match[1])) {
                $phpinfo[$match[1]] = array();
            } elseif (isset($match[3])) {
                $keys1 = array_keys($phpinfo);
                $phpinfo[end($keys1)][$fn($match[2])] = isset($match[4]) ? array($fn($match[3]), $fn($match[4])) : $fn($match[3]);
            } else {
                $keys1 = array_keys($phpinfo);
                $phpinfo[end($keys1)][] = $fn($match[2]);
            }

        }
    }
   
    return $phpinfo;
}

The output looks something like this (note the headers are also included but are prefixed with '# ', e.g. '# Directive'):

big thanx 2 Mardy dot Hutchinson at gmail dot com
very good!

some fixes to correct result displaying:
1. we need to trim $matches [1], 'cause there can be empty lines;
2. not bad to remove <body> tag 'cause styles for it not apply correctly...
3. ...and change styles a little (remove "body" selector)

we need to change two lines:

<?php
preg_match
('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
?>
to
<?php
preg_match
('%<style type="text/css">(.*?)</style>.*?<body>(.*?)</body>%s', ob_get_clean(), $matches);
?>

and

<?php
preg_split
( '/\n/', $matches[1] )
?>
to
<?php
preg_split
( '/\n/', trim(preg_replace( "/\nbody/", "\n", $matches[1])) )
?>

That's all! Now we have a really flexible addition to phpinfo();

Hi.

Here my version of saving php_info into an array:

<?php
function phpinfo_array()
{
   
ob_start();
   
phpinfo();
   
$info_arr = array();
   
$info_lines = explode("\n", strip_tags(ob_get_clean(), "<tr><td><h2>"));
   
$cat = "General";
    foreach(
$info_lines as $line)
    {
       
// new cat?
       
preg_match("~<h2>(.*)</h2>~", $line, $title) ? $cat = $title[1] : null;
        if(
preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
        {
           
$info_arr[$cat][$val[1]] = $val[2];
        }
        elseif(
preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
        {
           
$info_arr[$cat][$val[1]] = array("local" => $val[2], "master" => $val[3]);
        }
    }
    return
$info_arr;
}

// example:
echo "<pre>".print_r(phpinfo_array(), 1)."</pre>";

To extract all of the data from phpinfo into a nested array:
<?php
ob_start
();
phpinfo();
$phpinfo = array('phpinfo' => array());
if(
preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))
    foreach(
$matches as $match)
        if(
strlen($match[1]))
           
$phpinfo[$match[1]] = array();
        elseif(isset(
$match[3]))
           
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
        else
           
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
?>

Some examples of using individual values from the array:

<?php
   
echo "System: {$phpinfo['phpinfo']['System']}<br />\n";
    echo
"Safe Mode: {$phpinfo['PHP Core']['safe_mode'][0]}<br />\n";
    echo
"License: {$phpinfo['PHP License'][0]}<br />\n";
?>

To display everything:

<?php
   
foreach($phpinfo as $name => $section) {
        echo
"<h3>$name</h3>\n<table>\n";
        foreach(
$section as $key => $val) {
            if(
is_array($val))
                echo
"<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
            elseif(
is_string($key))
                echo
"<tr><td>$key</td><td>$val</td></tr>\n";
            else
                echo
"<tr><td>$val</td></tr>\n";
        }
        echo
"</table>\n";
    }
?>

Note: In order to properly retrieve all of the data, the regular expression matches table headers as well as table data, resulting in 'Local Value' and 'Global Value' showing up as 'Directive' entries.

<?php

// NOTE: When accessing a element from the above phpinfo_array(), you can do:
$array = phpinfo_array();

// This will work
echo $array["General"]["System "]; 

// This should work also, but it doesn't because there is a space after System in the array.
 
echo $array["General"]["System"]; 

// I hope the coder will fix it, so as to save someone else from wasting time. Otherwise, nice script.

This is necessary to obtain a W3C validation (XHTML1.0 Transitionnal)...
phpinfo's output is declared with that DTD :
- "System ID" has the wrong url to validate : "DTD/xhtml1-transitional.dtd" rather than "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
- Some module names contains space and the function's output use the name in anchors as ID and NAME. these attributes can't be validated like that (unique name only).

<?php

ob_start
();

ob_start ();                              // Capturing
phpinfo ();                               // phpinfo ()
$info = trim (ob_get_clean ());           // output

// Replace white space in ID and NAME attributes... if exists
$info = preg_replace ('/(id|name)(=["\'][^ "\']+) ([^ "\']*["\'])/i', '$1$2_$3', $info);

$imp = new DOMImplementation ();

All that could be done with only RegExp but I prefer the use of DOM for manipulating documents

I wanted a simple *function* to convert the output of phpinfo into an array.  Here's what I came up with thanks to alot of the previous authors tips, and the source file: php-5.2.6/ext/standard/info.c

Call this function like phpinfo_array() prints the array, phpinfo_array(1) returns the array for your own processing.

== Sample Output ==
[PHP Configuration] => Array
(
  [PHP Version] => 5.2.6
  [PHP Egg] => PHPE9568F34-D428-11d2-A769-00AA001ACF42
  [System] => Linux askapache 2.6.22.19-grsec3
  [Build Date] => Nov 11 2008 13:09:07
  [Configure Command] =>  ./configure --prefix=/home/grsec/bin/php
  [Server API] => FastCGI

  [IPv6 Support] => enabled
[Zend Egg] => PHPE9568F35-D428-11d2-A769-00AA001ACF42
  [PHP Credits Egg] => PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
)

[mbstring] => Array
(
  [mbstring.http_input] => pass
  [mbstring.internal_encoding] => Array
    (
     [0] => ISO-8859-1
     [1] => no value
    )

  [mbstring.language] => neutral
   )

[mcrypt] => Array
(
  [Version] => 3.5.7
  [Api No] => 20031217
)

<?php
function phpinfo_array($return=false){
/* Andale!  Andale!  Yee-Hah! */
ob_start();
phpinfo(-1);

$pi = preg_replace(
array(
'#^.*<body>(.*)</body>.*$#ms', '#<h2>PHP License</h2>.*$#ms',
'#<h1>Configuration</h1>#'"#\r?\n#", "#</(h1|h2|h3|tr)>#", '# +<#',
"#[ \t]+#", '#&nbsp;#', '#  +#', '# class=".*?"#', '%&#039;%',
 
'#<tr>(?:.*?)" src="(?:.*?)=(.*?)" alt="PHP Logo" /></a>'
 
.'<h1>PHP Version (.*?)</h1>(?:\n+?)</td></tr>#',
 
'#<h1><a href="(?:.*?)\?=(.*?)">PHP Credits</a></h1>#',
 
'#<tr>(?:.*?)" src="(?:.*?)=(.*?)"(?:.*?)Zend Engine (.*?),(?:.*?)</tr>#',
 
"# +#", '#<tr>#', '#</tr>#'),
array(
'$1', '', '', '', '</$1>' . "\n", '<', ' ', ' ', ' ', '', ' ',
 
'<h2>PHP Configuration</h2>'."\n".'<tr><td>PHP Version</td><td>$2</td></tr>'.
 
"\n".'<tr><td>PHP Egg</td><td>$1</td></tr>',
 
'<tr><td>PHP Credits Egg</td><td>$1</td></tr>',
 
'<tr><td>Zend Engine</td><td>$2</td></tr>' . "\n" .
 
'<tr><td>Zend Egg</td><td>$1</td></tr>', ' ', '%S%', '%E%'),
ob_get_clean());

$sections = explode('<h2>', strip_tags($pi, '<h2><th><td>'));
unset(
$sections[0]);

$pi = array();
foreach(
$sections as $section){
  
$n = substr($section, 0, strpos($section, '</h2>'));
  
preg_match_all(
  
'#%S%(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?%E%#',
    
$section, $askapache, PREG_SET_ORDER);
   foreach(
$askapache as $m)
      
$pi[$n][$m[1]]=(!isset($m[3])||$m[2]==$m[3])?$m[2]:array_slice($m,2);
}

return (
$return === false) ? print_r($pi) : $pi;
}

One note on the above functions for cleaning up the phpinfo() HTML and throwing it into an array data structure. In order to catch all of the info tidbits the preg_match_all has to be tweaked to deal with 2 and 3 column tables.

I have changed the preg_match_all() here so that the last <td></td> is optional

<?php
function parsePHPConfig() {
   
ob_start();
   
phpinfo(-1);
   
$s = ob_get_contents();
   
ob_end_clean();
   
$a = $mtc = array();
    if (
preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td>(:?<td class="v">(.*?)<\/td>)?<\/tr>/',$s,$mtc,PREG_SET_ORDER))
        foreach(
$mtc as $v){
            if(
$v[2] == '<i>no value</i>') continue;
           
$a[$v[1]] = $v[2];
        }
    }
    return
$a;
}
?>

check out this cool and fantastic colourful phpinfo()!

<?php

ob_start
();
phpinfo();
$phpinfo = ob_get_contents();
ob_end_clean();

preg_match_all('/#[0-9a-fA-F]{6}/', $phpinfo, $rawmatches);
for (
$i = 0; $i < count($rawmatches[0]); $i++)
  
$matches[] = $rawmatches[0][$i];
$matches = array_unique($matches);

$hexvalue = '0123456789abcdef';

$j = 0;
foreach (
$matches as $match)
{

  
$r = '#';
  
$searches[$j] = $match;
   for (
$i = 0; $i < 6; $i++)
     
$r .= substr($hexvalue, mt_rand(0, 15), 1);
  
$replacements[$j++] = $r;
   unset(
$r);
}

for (
$i = 0; $i < count($searches); $i++)
  
$phpinfo = str_replace($searches, $replacements, $phpinfo);
echo
$phpinfo;
?>

here you can notice that these numeric values of phpinfo
are similar to certain things in the binary system:

-1, coded in 7 digits:
111 1111

look at this:
1+2+4+8+16+32+64=127

unsigned,127 is:
111 1111

so, take a look at this: the way to get all function is to add all of them. zero is nothing.-1 is all.
so you can pass option with a negative number.
for example:
<?php phpinfo(48) ?>
is also:
<?php phpinfo(-80) ?>
48 = 32 + 16
-80= 0 - 64 - 8 - 4 - 2 - 1

so you can see in negative mode it like that:
not nothing
not all (-1) don't forget it !
not option 64
not option 8
not option 4
not option 2

so, that's good if you don't want option 8, you will do this:
not nothing(0)
not all(-1)
not option 8(-1)
you got:
<?php phpinfo(-9); ?>

hope this will be useful, that's my 1rst post ^^

This function parses the phpinfo output to get details about a PHP module.

<?php
/** parse php modules from phpinfo */
function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();

$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for (
$i=1;$i<count($vTmp);$i++) {
  if (
preg_match('/<h2>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
  
$vName = trim($vMat[1]);
  
$vTmp2 = explode("\n",$vTmp[$i+1]);
   foreach (
$vTmp2 AS $vOne) {
   
$vPat = '<info>([^<]+)<\/info>';
   
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
   
$vPat2 = "/$vPat\s*$vPat/";
    if (
preg_match($vPat3,$vOne,$vMat)) { // 3cols
    
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
    } elseif (
preg_match($vPat2,$vOne,$vMat)) { // 2cols
    
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
    }
   }
  }
}
return
$vModules;
}
?>

Sample Output:
[gd] => Array
(
  [GD Support] => enabled
  [GD Version] => bundled (2.0.28 compatible)
  [FreeType Support] => enabled
  [FreeType Linkage] => with freetype
  [FreeType Version] => 2.1.9
  [T1Lib Support] => enabled
  [GIF Read Support] => enabled
  [GIF Create Support] => enabled
  [JPG Support] => enabled
  [PNG Support] => enabled
  [WBMP Support] => enabled
  [XBM Support] => enabled
)

[date] => Array (
  [date/time support] => enabled
  [Timezone Database Version] => 2005.14
  [Timezone Database] => internal
  [Default timezone] => America/Los_Angeles
  [Directive] => Array (
     [0] => Local Value
     [1] => Master Value
  )
  [date.timezone] => Array (
     [0] => no value
     [1] => no value
  )
)


<?php
/** get a module setting */
function getModuleSetting($pModuleName,$pSetting) {
$vModules = parsePHPModules();
return
$vModules[$pModuleName][$pSetting];
}
?>

Example: getModuleSetting('gd','GD Version'); returns "bundled (2.0.28 compatible)"

This is a slight modification to the previous code by "code at adspeed dot com" that extracts the PHP modules as an array. I used it on PHP 4.1.2 and it failed as the <h2> tags also had an align="center". So this update changes the regex for those tags:

<?php

/* parse php modules from phpinfo */

function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();

$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2[^>]*>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for (
$i=1;$i<count($vTmp);$i++) {
  if (
preg_match('/<h2[^>]*>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
  
$vName = trim($vMat[1]);
  
$vTmp2 = explode("\n",$vTmp[$i+1]);
   foreach (
$vTmp2 AS $vOne) {
  
$vPat = '<info>([^<]+)<\/info>';
  
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
  
$vPat2 = "/$vPat\s*$vPat/";
   if (
preg_match($vPat3,$vOne,$vMat)) { // 3cols
    
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
   } elseif (
preg_match($vPat2,$vOne,$vMat)) { // 2cols
    
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
   }
   }
  }
}
return
$vModules;
}
?>

Building on SimonD's elegant example to hide the logged-in username and password, which otherwise appear in plain text, the following should work for PHP 5.4+:

<?php
   
// start output buffering
   
ob_start();

   
// send phpinfo content
   
phpinfo();

   
// get phpinfo content
   
$html = ob_get_contents();

   
// flush the output buffer
   
ob_end_clean();

   
// remove auth data
   
if ( isset( $_SERVER[ 'PHP_AUTH_USER' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_USER' ], '[ protected ]' , $html);
    if ( isset(
$_SERVER[ 'PHP_AUTH_PW' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_PW' ], '[ protected ]' , $html);

    echo
$html;
?>

To remove additional items, just add them as above.
