mb_convert_encoding

(PHP 4 >= 4.0.6, PHP 5, PHP 7, PHP 8)

mb_convert_encoding — Convert a string from one character encoding to another

Description

Converts string from from_encoding, or the current internal encoding, to to_encoding. If string is an array, all its string values will be converted recursively.

Parameters

string

The string or array to be converted.

to_encoding

The desired encoding of the result.

from_encoding

The current encoding used to interpret string. Multiple encodings may be specified as an array or comma separated list, in which case the correct encoding will be guessed using the same algorithm as mb_detect_encoding().

If from_encoding is omitted or null, the mbstring.internal_encoding setting will be used if set, otherwise the default_charset setting.

See supported encodings for valid values of to_encoding and from_encoding.

Return Values

The encoded string or array on success, or false on failure.

Errors/Exceptions

As of PHP 8.0.0, a ValueError is thrown if the value of to_encoding or from_encoding is an invalid encoding. Prior to PHP 8.0.0, a E_WARNING was emitted instead.

Changelog

Version	Description
8.2.0	mb_convert_encoding() will no longer return the following non text encodings: `"Base64"`, `"QPrint"`, `"UUencode"`, `"HTML entities"`, `"7 bit"` and `"8 bit"`.
8.0.0	mb_convert_encoding() will now throw a ValueError when `to_encoding` is passed an invalid encoding.
8.0.0	mb_convert_encoding() will now throw a ValueError when `from_encoding` is passed an invalid encoding.
8.0.0	`from_encoding` is nullable now.
7.2.0	This function now also accepts an array as `string`. Formerly, only strings have been supported.

Examples

Example #1 mb_convert_encoding() example

<?php
/* Convert internal character encoding to SJIS */
$str = mb_convert_encoding($str, "SJIS");

/* Convert EUC-JP to UTF-7 */
$str = mb_convert_encoding($str, "UTF-7", "EUC-JP");

/* Auto detect encoding from JIS, eucjp-win, sjis-win, then convert str to UCS-2LE */
$str = mb_convert_encoding($str, "UCS-2LE", "JIS, eucjp-win, sjis-win");

/* If mbstring.language is "Japanese", "auto" is expanded to "ASCII,JIS,UTF-8,EUC-JP,SJIS" */
$str = mb_convert_encoding($str, "EUC-JP", "auto");
?>

For my last project I needed to convert several CSV files from Windows-1250 to UTF-8, and after several days of searching around I found a function that is partially solved my problem, but it still has not transformed all the characters. So I made this:

function w1250_to_utf8($text) {
    // map based on:
    // http://konfiguracja.c0.pl/iso02vscp1250en.html
    // http://konfiguracja.c0.pl/webpl/index_en.html#examp
    // http://www.htmlentities.com/html/entities/
    $map = array(
        chr(0x8A) => chr(0xA9),
        chr(0x8C) => chr(0xA6),
        chr(0x8D) => chr(0xAB),
        chr(0x8E) => chr(0xAE),
        chr(0x8F) => chr(0xAC),
        chr(0x9C) => chr(0xB6),
        chr(0x9D) => chr(0xBB),
        chr(0xA1) => chr(0xB7),
        chr(0xA5) => chr(0xA1),
        chr(0xBC) => chr(0xA5),
        chr(0x9F) => chr(0xBC),
        chr(0xB9) => chr(0xB1),
        chr(0x9A) => chr(0xB9),
        chr(0xBE) => chr(0xB5),
        chr(0x9E) => chr(0xBE),
        chr(0x80) => '&euro;',
        chr(0x82) => '&sbquo;',
        chr(0x84) => '&bdquo;',
        chr(0x85) => '&hellip;',
        chr(0x86) => '&dagger;',
        chr(0x87) => '&Dagger;',

        chr(0xB5) => '&micro;',
        chr(0xB6) => '&para;',
        chr(0xB7) => '&middot;',
        chr(0xBB) => '&raquo;',
    );
    return html_entity_decode(mb_convert_encoding(strtr($text, $map), 'UTF-8', 'ISO-8859-2'), ENT_QUOTES, 'UTF-8');
}

If you have what looks like ISO-8859-1, but it includes "smart quotes" courtesy of Microsoft software, or people cutting and pasting content from Microsoft software, then what you're actually dealing with is probably Windows-1252. Try this:

<?php
$cleanText = mb_convert_encoding($text, 'UTF-8', 'Windows-1252');
?>

The annoying part is that the auto detection (ie: the mb_detect_encoding function) will often think Windows-1252 is ISO-8859-1. Close, but no cigar. This is critical if you're then trying to do unserialize on the resulting text, because the byte count of the string needs to be perfect.

I've been trying to find the charset of a norwegian (with a lot of ø, æ, å) txt file written on a Mac, i've found it in this way:



<?php

$text = "A strange string to pass, maybe with some ø, æ, å characters.";



foreach(mb_list_encodings() as $chr){

        echo mb_convert_encoding($text, 'UTF-8', $chr)." : ".$chr."<br>";    

 } 

?>



The line that looks good, gives you the encoding it was written in.



Hope can help someone

Hey guys. For everybody who's looking for a function that is converting an iso-string to utf8 or an utf8-string to iso, here's your solution:

public function encodeToUtf8($string) {
     return mb_convert_encoding($string, "UTF-8", mb_detect_encoding($string, "UTF-8, ISO-8859-1, ISO-8859-15", true));
}

public function encodeToIso($string) {
     return mb_convert_encoding($string, "ISO-8859-1", mb_detect_encoding($string, "UTF-8, ISO-8859-1, ISO-8859-15", true));
}

For me these functions are working fine. Give it a try

Text-encoding HTML-ENTITIES will be deprecated as of PHP 8.2.

To convert all non-ASCII characters into entities (to produce pure 7-bit HTML output), I was using:

<?php
echo mb_convert_encoding( htmlspecialchars( $text, ENT_QUOTES, 'UTF-8' ), 'HTML-ENTITIES', 'UTF-8' );
?>

I can get the identical result with:

<?php
echo mb_encode_numericentity( htmlentities( $text, ENT_QUOTES, 'UTF-8' ), [0x80, 0x10FFFF, 0, ~0], 'UTF-8' );
?>

The output contains well-known named entities for some often used characters and numeric entities for the rest.

aaron, to discard unsupported characters instead of printing a ?, you might as well simply set the configuration directive:

mbstring.substitute_character = "none"

in your php.ini. Be sure to include the quotes around none. Or at run-time with

<?php
ini_set('mbstring.substitute_character', "none");
?>

My solution below was slightly incorrect, so here is the correct version (I posted at the end of a long day, never a good idea!)

Again, this is a quick and dirty solution to stop mb_convert_encoding from filling your string with question marks whenever it encounters an illegal character for the target encoding. 

<?php
function convert_to ( $source, $target_encoding )
    {
    // detect the character encoding of the incoming file
    $encoding = mb_detect_encoding( $source, "auto" );
       
    // escape all of the question marks so we can remove artifacts from
    // the unicode conversion process
    $target = str_replace( "?", "[question_mark]", $source );
       
    // convert the string to the target encoding
    $target = mb_convert_encoding( $target, $target_encoding, $encoding);
       
    // remove any question marks that have been introduced because of illegal characters
    $target = str_replace( "?", "", $target );
       
    // replace the token string "[question_mark]" with the symbol "?"
    $target = str_replace( "[question_mark]", "?", $target );
   
    return $target;
    }
?>

Hope this helps someone! (Admins should feel free to delete my previous, incorrect, post for clarity)

many people below talk about using 

<?php

    mb_convert_encode($s,'HTML-ENTITIES','UTF-8');

?>

to convert non-ascii code into html-readable stuff.  Due to my webserver being out of my control, I was unable to set the database character set, and whenever PHP made a copy of my $s variable that it had pulled out of the database, it would convert it to nasty latin1 automatically and not leave it in it's beautiful UTF-8 glory.



So [insert korean characters here] turned into ?????.



I found myself needing to pass by reference (which of course is deprecated/nonexistent in recent versions of PHP)

so instead of

<?php

    mb_convert_encode(&$s,'HTML-ENTITIES','UTF-8');

?>

which worked perfectly until I upgraded, so I had to use

<?php

    call_user_func_array('mb_convert_encoding', array(&$s,'HTML-ENTITIES','UTF-8'));

?>



Hope it helps someone else out

To add to the Flash conversion comment below, here's how I convert back from what I've stored in a database after converting from Flash HTML text field output, in order to load it back into a Flash HTML text field:

function htmltoflash($htmlstr)
{
  return str_replace("&lt;br /&gt;","\n",
    str_replace("<","&lt;",
      str_replace(">","&gt;",
        mb_convert_encoding(html_entity_decode($htmlstr),
        "UTF-8","ISO-8859-1"))));
}

If you are trying to generate a CSV (with extended chars) to be opened at Exel for Mac, the only that worked for me was:

<?php mb_convert_encoding( $CSV, 'Windows-1252', 'UTF-8'); ?>



I also tried this:



<?php

//Separado OK, chars MAL

iconv('MACINTOSH', 'UTF8', $CSV);

//Separado MAL, chars OK

chr(255).chr(254).mb_convert_encoding( $CSV, 'UCS-2LE', 'UTF-8');

?>



But the first one didn't show extended chars correctly, and the second one, did't separe fields correctly

It appears that when dealing with an unknown "from encoding" the function will both throw an E_WARNING and proceed to convert the string from ISO-8859-1 to the "to encoding".

When you need to convert from HTML-ENTITIES, but your UTF-8 string is partially broken (not all chars in UTF-8) - in this case passing string to mb_convert_encoding($string, 'UTF-8', 'HTML-ENTITIES'); - corrupts chars in string even more. In this case you need to replace html entities gradually to preserve character good encoding. I wrote such closure for this job :
<?php
$decode_entities = function($string) {
        preg_match_all("/&#?\w+;/", $string, $entities, PREG_SET_ORDER);
        $entities = array_unique(array_column($entities, 0));
        foreach ($entities as $entity) {
            $decoded = mb_convert_encoding($entity, 'UTF-8', 'HTML-ENTITIES');
            $string = str_replace($entity, $decoded, $string);
        }
        return $string;
    };
?>

Note that `mb_convert_encoding($val, 'HTML-ENTITIES')` does not escape '\'', '"', '<', '>', or '&'.

Clean a string for use as filename by simply replacing all unwanted characters with underscore (ASCII converts to 7bit). It removes slightly more chars than necessary. Hope its useful. 

$fileName = 'Test:!"$%&/()=ÖÄÜöäü<<';
echo strtr(mb_convert_encoding($fileName,'ASCII'), 
    ' ,;:?*#!§$%&/(){}<>=`´|\\\'"',

Why did you use the php html encode functions? mbstring has it's own Encoding which is (as far as I tested it) much more usefull:

HTML-ENTITIES

Example:

$text = mb_convert_encoding($text, 'HTML-ENTITIES', "UTF-8");

If you are attempting to convert "UTF-8" text to "ISO-8859-1" and the result is always returning in "ASCII", place the following line of code before the mb_convert_encoding:

mb_detect_order(array('UTF-8', 'ISO-8859-1'));

It is necessary to force a specific search order for the conversion to work

For those wanting to convert from $set to MacRoman, use iconv():

<?php

$string = iconv('UTF-8', 'macintosh', $string);

?>

('macintosh' is the IANA name for the MacRoman character set.)

As an alternative to Johannes's suggestion for converting strings from other character sets to a 7bit representation while not just deleting latin diacritics, you might try this:

<?php
$text = iconv($from_enc, 'US-ASCII//TRANSLIT', $text);
?>

The only disadvantage is that it does not convert "ä" to "ae", but it handles punctuation and other special characters better.

When converting Japanese strings to ISO-2022-JP or JIS on PHP >= 5.2.1, you can use "ISO-2022-JP-MS" instead of them.
Kishu-Izon (platform dependent) characters are converted correctly with the encoding, as same as with eucJP-win or with SJIS-win.

be careful when converting from iso-8859-1 to utf-8.

even if you explicitly specify the character encoding of a page as iso-8859-1(via headers and strict xml defs), windows 2000 will ignore that and interpret it as whatever character set it has natively installed. 

for example, i wrote char #128 into a page, with char encoding iso-8859-1, and it displayed in internet explorer (& mozilla) as a euro symbol.

it should have displayed a box, denoting that char #128 is undefined in iso-8859-1. The problem was it was displaying in "Windows: western europe" (my native character set).

this led to confusion when i tried to convert this euro to UTF-8 via mb_convert_encoding()  

IE displays UTF-8 correctly- and because PHP correctly converted #128 into a box in UTF-8, IE would show a box.

so all i saw was mb_convert_encoding() converting a euro symbol into a box. It took me a long time to figure out what was going on.

For the php-noobs (like me) - working with flash and php.

Here's a simple snippet of code that worked great for me, getting php to show special Danish characters, from a Flash email form:

<?php
// Name Escape
$escName = mb_convert_encoding($_POST["Name"], "ISO-8859-1", "UTF-8");

// message escape
$escMessage = mb_convert_encoding($_POST["Message"], "ISO-8859-1", "UTF-8");

// Headers.. and so on...
?>

rodrigo at bb2 dot co dot jp wrote that inconv works better than mb_convert_encoding, I find that when converting from uft8 to shift_jis 
$conv_str = mb_convert_encoding($str,$toCS,$fromCS); 
works while
$conv_str = iconv($fromCS,$toCS.'//IGNORE',$str); 
removes tildes from $str.

If you want to convert japanese to ISO-2022-JP it is highly recommended to use ISO-2022-JP-MS as the target encoding instead. This includes the extended character set and avoids ? in the text. For example the often used "1 in a circle" ① will be correctly converted then.

For those who can´t use mb_convert_encoding() to convert from one charset to another as a metter of lower version of php, try iconv().

I had this problem converting to japanese charset:

$txt=mb_convert_encoding($txt,'SJIS',$this->encode);

And I could fix it by using this:

$txt = iconv('UTF-8', 'SJIS', $txt);

Maybe it´s helpfull for someone else! ;)

I\&#039;d like to share some code to convert latin diacritics to their

traditional 7bit representation, like, for example,



- &agrave;,&ccedil;,&eacute;,&icirc;,... to a,c,e,i,...

- &szlig; to ss

- &auml;,&Auml;,... to ae,Ae,...

- &euml;,... to e,...



(mb_convert \&quot;7bit\&quot; would simply delete any offending characters). 



I might have missed on your country\&#039;s typographic 

conventions--correct me then. 

&lt;?php

/**

 * @args string $text line of encoded text

 *       string $from_enc (encoding type of $text, e.g. UTF-8, ISO-8859-1)

 *

 * @returns 7bit representation

 */

function to7bit($text,$from_enc) {

    $text = mb_convert_encoding($text,\&#039;HTML-ENTITIES\&#039;,$from_enc);

    $text = preg_replace(

        array(\&#039;/&szlig;/\&#039;,\&#039;/&amp;(..)lig;/\&#039;,

             \&#039;/&amp;([aouAOU])uml;/\&#039;,\&#039;/&amp;(.)[^;]*;/\&#039;),

        array(\&#039;ss\&#039;,\&quot;$1\&quot;,\&quot;$1\&quot;.\&#039;e\&#039;,\&quot;$1\&quot;),

        $text);

    return $text;

}   

?&gt;



Enjoy :-)

An addendum to my &quot;to7bit&quot; function referenced below in the notes. 

The function is supposed to solve the problem that some languages require a different 7bit rendering of special (umlauted) characters for sorting or other applications. For example, the German &szlig; ligature is usually written &quot;ss&quot; in 7bit context. Dutch &yuml; is typically rendered &quot;ij&quot; (not &quot;y&quot;). 



The original function works well with word (alphabet) character entities and I&#039;ve seen it used in many places. But non-word entities cause funny results:

E.g., &quot;&copy;&quot; is rendered as &quot;c&quot;, &quot;&shy;&quot; as &quot;s&quot; and &quot;&amp;rquo;&quot; as &quot;r&quot;. 

The following version fixes this by converting non-alphanumeric characters (also chains thereof) to &#039;_&#039;.



&lt;?php

/**

 * @args string $text line of encoded text

 *       string $from_enc (encoding type of $text, e.g. UTF-8, ISO-8859-1)

 *

 * @returns 7bit representation

 */

function to7bit($text,$from_enc) {

    $text = preg_replace(/W+/,&#039;_&#039;,$text);

    $text = mb_convert_encoding($text,&#039;HTML-ENTITIES&#039;,$from_enc);

    $text = preg_replace(

        array(&#039;/&szlig;/&#039;,&#039;/&amp;(..)lig;/&#039;,

             &#039;/&amp;([aouAOU])uml;/&#039;,&#039;/&yuml;/&#039;,&#039;/&amp;(.)[^;]*;/&#039;),

        array(&#039;ss&#039;,&quot;$1&quot;,&quot;$1&quot;.&#039;e&#039;,&#039;ij&#039;,&quot;$1&quot;),

        $text);

    return $text;

}  

?&gt;



Enjoy again,

Johannes

Here's a tip for anyone using Flash and PHP for storing HTML output submitted from a Flash text field in a database or whatever.

Flash submits its HTML special characters in UTF-8, so you can use the following function to convert those into HTML entity characters:

function utf8html($utf8str)
{
  return htmlentities(mb_convert_encoding($utf8str,"ISO-8859-1","UTF-8"));
}
