curl_setopt_array

(PHP 5 >= 5.1.3)

curl_setopt_arraySet multiple options for a cURL transfer

Description

bool curl_setopt_array ( resource $ch , array $options )

Sets multiple options for a cURL session. This function is useful for setting a large amount of cURL options without repetitively calling curl_setopt().

Parameters

ch

A cURL handle returned by curl_init().

options

An array specifying which options to set and their values. The keys should be valid curl_setopt() constants or their integer equivalents.

Return Values

Returns TRUE if all options were successfully set. If an option could not be successfully set, FALSE is immediately returned, ignoring any future options in the options array.

Examples

Example #1 Initializing a new cURL session and fetching a web page

<?php
// create a new cURL resource
$ch curl_init();

// set URL and other appropriate options
$options = array(CURLOPT_URL => 'http://www.example.com/',
                 
CURLOPT_HEADER => false
                
);

curl_setopt_array($ch$options);

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
?>

Prior to PHP 5.1.3 this function can be simulated with:

Example #2 Our own implementation of curl_setopt_array()

<?php
if (!function_exists('curl_setopt_array')) {
   function 
curl_setopt_array(&$ch$curl_options)
   {
       foreach (
$curl_options as $option => $value) {
           if (!
curl_setopt($ch$option$value)) {
               return 
false;
           } 
       }
       return 
true;
   }
}
?>

Notes

Note:

As with curl_setopt(), passing an array to CURLOPT_POST will encode the data as multipart/form-data, while passing a URL-encoded string will encode the data as application/x-www-form-urlencoded.

In case that you need to read SSL page content from https with curl, this function can help you:

<?php

function get_web_page( $url,$curl_data )
{
   
$options = array(
       
CURLOPT_RETURNTRANSFER => true,         // return web page
       
CURLOPT_HEADER         => false,        // don't return headers
       
CURLOPT_FOLLOWLOCATION => true,         // follow redirects
       
CURLOPT_ENCODING       => "",           // handle all encodings
       
CURLOPT_USERAGENT      => "spider",     // who am i
       
CURLOPT_AUTOREFERER    => true,         // set referer on redirect
       
CURLOPT_CONNECTTIMEOUT => 120,          // timeout on connect
       
CURLOPT_TIMEOUT        => 120,          // timeout on response
       
CURLOPT_MAXREDIRS      => 10,           // stop after 10 redirects
       
CURLOPT_POST            => 1,            // i am sending post data
          
CURLOPT_POSTFIELDS     => $curl_data,    // this are my post vars
       
CURLOPT_SSL_VERIFYHOST => 0,            // don't verify ssl
       
CURLOPT_SSL_VERIFYPEER => false,        //
       
CURLOPT_VERBOSE        => 1                //
   
);

   
$ch      = curl_init($url);
   
curl_setopt_array($ch,$options);
   
$content = curl_exec($ch);
   
$err     = curl_errno($ch);
   
$errmsg  = curl_error($ch) ;
   
$header  = curl_getinfo($ch);
   
curl_close($ch);

 
//  $header['errno']   = $err;
  //  $header['errmsg']  = $errmsg;
  //  $header['content'] = $content;
   
return $header;
}

$curl_data = "var1=60&var2=test";
$url = "https://www.example.com";
$response = get_web_page($url,$curl_data);

print
'<pre>';
print_r($response);

Starting in PHP 5.2.0, CURLOPT_FOLLOWLOCATION can't be set via curl_setopt_array() (or curl_setopt()) when either safe_mode is enabled or open_basedir is set.  In these cases, the order of CURLOPT_* settings in the array can be important.

You can use CURLOPT_HEADERFUNCTION  with a callback inside an object.  This makes is it easy to capture the headers for later use.  For example:

<?php
class Test
{
    public
$headers;

   
//...

   
public function exec($opts)
    {
       
$this->headers = array();
       
$opts[CURLOPT_HEADERFUNCTION] = array($this, '_setHeader');
       
$ch = curl_init();
       
curl_setopt_array($ch, $opts);
        return
curl_exec($ch);
    }

    private function
_setHeader($ch, $header)
    {
       
$this->headers[] = $header;
        return
strlen($header);
    }

   
}

$test = new Test();
$opts = array(
  
//... your curl opts here
);
$data = $test->exec($opts);
print_r($test->headers);
?>

...something like that

(This works in php v. 5.1.4)

it should be noted that when using CURLOPT_POSTFIELDS in a loop, CURLOPT_POSTFIELDS appends to the sting. You can use unset() if you don't want this sort of behavior.

<?php
//this will append postfields

while(true) {
   
$options = array(CURLOPT_POSTFIELDS => 'foo=bar&foo2=bar');
   
$ch = curl_init("http://www.example.com");
   
curl_setopt_array($ch, $options);
   
curl_exec($ch);
   
curl_close($ch);
}

//this will NOT append postfields
while(true) {
   
$options = array(CURLOPT_POSTFIELDS => 'foo=bar&foo2=bar');
   
$ch = curl_init("http://www.example.com");
   
curl_setopt_array($ch, $options);
   
curl_exec($ch);
   
curl_close($ch);
    unset(
$options[CURLOPT_POSTFIELDS]);
}
?>

There is no CURLOPT_MAXFILESIZE in the PHP module but it's function only works with Content-Length headers anyway.  There are two ways of checking download sizes, one is after the download is complete using filesize(), the other is as the download is running allowing you to terminate before wasting time and disk space.

<?php
$GLOBALS
['file_size'] = 0;
$GLOBALS['max_file_size'] = 1024 * 1024;
function
on_curl_header($ch, $header)
{
   
$trimmed = rtrim($header);   
    if (
preg_match('/^Content-Length: (\d+)$/', $trimmed, $matches))
    {
       
$file_size = $matches[1];
        if (
$file_size > $GLOBALS['max_file_size']) {
           
// handle error here.
       
}
    }
    return
strlen($header);
}

function
on_curl_write($ch, $data)
{
   
$bytes = strlen($data);
   
$GLOBALS['file_size'] += $bytes;
    if (
$GLOBALS['file_size'] > $GLOBALS['max_file_size']) {
       
// handle error here.
   
}
    return
$bytes;
}

$ch = curl_init();
$options = array(CURLOPT_URL        => 'http://www.php.net/',
        
CURLOPT_HEADER        => false,
        
CURLOPT_HEADERFUNCTION    => 'on_curl_header',
        
CURLOPT_WRITEFUNCTION    => 'on_curl_write');
curl_setopt_array($ch, $options);
curl_exec($ch);
// ...
?>
