mb_ereg_replace — Replace regular expression with multibyte support

Описание

string mb_ereg_replace ( string $pattern , string $replacement , string $string [, string $option ] )

Scans string for matches to pattern , then replaces the matched text with replacement

Список параметров

pattern

The regular expression pattern.

Multibyte characters may be used in pattern .

replacement

The replacement text.

string

The string being checked.

option
Matching condition can be set by option parameter. If i is specified for this parameter, the case will be ignored. If x is specified, white space will be ignored. If m is specified, match will be executed in multiline mode and line break will be included in '.'. If p is specified, match will be executed in POSIX mode, line break will be considered as normal character. If e is specified, replacement string will be evaluated as PHP expression.

Возвращаемые значения

The resultant string on success, or FALSE on error.

Примечания

Замечание: The internal encoding or the character encoding specified by mb_regex_encoding() will be used as the character encoding for this function.

A simple mb_str_ireplace() implementation - a faster (?) replacement for non-regexp multi-byte string replacement:

<?php
function mb_str_ireplace($co$naCo$wCzym)
{
   
$wCzymM mb_strtolower($wCzym);
   
$coM    mb_strtolower($co);
   
$offset 0;
   
        while(!
is_bool($poz mb_strpos($wCzymM$coM$offset)))
    {
       
$offset $poz mb_strlen($naCo);
       
$wCzym mb_substr($wCzym0$poz). $naCo .mb_substr($wCzym$poz+mb_strlen($co));
       
$wCzymM mb_strtolower($wCzym);
    }
   
    return 
$wCzym;
}
?>

Are you looking for htmlentities() for multibyte strings? This might help you - it just replace <, >, ", '

<?php
/**
 *  Multibyte equivalent for htmlentities() [lite version :)]
 *
 * @param string $str
 * @param string $encoding
 * @return string
 **/
function mb_htmlentities($str$encoding 'utf-8') {
   
mb_regex_encoding($encoding);
   
$pattern = array('<''>''"''\'');
   
$replacement = array('&lt;''&gt;''&quot;''&#39;');
    for (
$i=0$i<sizeof($pattern); $i++) {
       
$str mb_ereg_replace($pattern[$i], $replacement[$i], $str);
    }
    return 
$str;
}
?>

Regarding the mb_str_ireplace() function: I benchmarked it against mb_eregi_replace() for single-character substitution, and it was significantly slower. Despite avoiding the ereg call, I think the while loop ends slowing you down too much for this to be practical.

well, if you just calculated the length of the find and replace strings once instead of on every loop, it would likely speed it up a lot.

'i' option does not work correctly with multibyte characters. The function does not locate/replace the multibyte string if it's different case then specified on multibyte needle which is in different case.

If you want to replace characters like "ä" or "ø" you can use mb_ereg_replace, but it is very slow. str_replace is much faster and also works with characters like "ä" or "ø"!

I think this has something to with the fact that str_replace works on byte level and does not care about characters.
I hope that can help.

<?php
$pattern 
"([あ-ん]+)[0-9]+";
$string mb_ereg_replace($pattern'「\\1」:\\0'$string);
?>

you can use \\n for capture group in replacement

I got a pretty nasty error while trying to parse table rows(all contents were set to UTF-8) from the database for a dictionary project. The idea was to get all the rows from the first table (that is a table with bulgarian phrase in the first field, and its translation in english, french and german in the next fields). I needed to index all the bulgarian words that are found in the table to make an intelligent search. And that is where my headache started.

First of all, even with mb_strtolower() a lot of cyrillic characters went corrupted (ex: 'т,ъ,у,ф,б,г,з,ж,' etc...). After an hour of different attempts I got such a solution:

<?php

mb_internal_encoding
("UTF-8");
mb_regex_encoding("UTF-8");

$rows $db->getRows();

$contents = array();
foreach (
$rows as $eachRow)
{
   
$cleared str_replace($commonWords' 'mb_strtolower(stripslashes($eachRow['bulgarian']), 'UTF-8' ));
    if (
trim($cleared) != ''$contents[] = trim($cleared);
}   

$list = array();
foreach (
$contents as $eachRow)
{
   
$exploded explode(' '$eachRow);
    foreach (
$exploded as $eachExpl)
    {
       
$eachExpl mb_ereg_replace('[^а-я ]',' '$eachExpl);
        if (
trim($eachExpl) != ''
            if (!
in_array($eachExpl$listtrue))    $list[] = trim($eachExpl);
    }
}

?>

To work properly I got to set all the internal encoding settings to UTF-8. Else the default Latin-1 got half my database with missing characters.

I am posting this solution just in case someone has encountered a similar problem. Hope it helps you in case you need something like that.

Unlike preg_replace, mb_ereg_replace doesn't use separators

Exemple with preg_replace :
<?php $data preg_replace("/[^A-Za-z0-9\.\-]/","",$data); ?>

Exemple with mb_ereg_replace :
<?php $data mb_ereg_replace("[^A-Za-z0-9\.\-]","",$data); ?>

You can use \\n for capture group in replacement.
And you can NOT use $n notation (unlike preg_replace function).

To selectively uppercase parts of a string via mb_eregi_replace

    $str = mb_eregi_replace('\b([0-9]{1,4}[a-z]{1,2})\b', "strtoupper
('\\1')", $str, 'e');

Full example, how to fix an address manually typed, uppercasing the first letter of a words and keeping uppercase roman numerals and the letters A,B,C after the house number):

function ucAddress($str) {
// first lowercase all and use the default ucwords
    $str = ucwords(strtolower($str));
// let's fix the default ucwords...
// uppercase letters after house number (was lowercased by the strtolower above)
    $str = mb_eregi_replace('\b([0-9]{1,4}[a-z]{1,2})\b', "strtoupper
('\\1')", $str, 'e');
// the same for roman numerals
    $str = mb_eregi_replace('\bM{0,4}(CM|CD|D?C{0,3})(XC|XL|L?X{0,3})(IX|IV|V?I{0,3})\b', "strtoupper('\\0')", $str, 'e');
    return $str;
}

Pluche's comment should REALLY be added to the documentation, preferably under the "$pattern" param description. It is crucial to using this function.

As trng mentioned before you can use \\n for replacement but NOT \\\\n as mentioned in preg_replace docs. So string definition will be like:
$str = '\\1';

If encoding of PHP script differs from encoding of string to be processed by mb_ereg_replace(), then you can't just write pattern in script. Both $pattern and $replacement must be converted to same encoding as string to be processed. In this example script is in UTF-8, file to be processed is in UTF-16LE encoding:

<?php
$file_encoding 
'UTF-16LE';
mb_regex_encoding$file_encoding );

$pattern     "aaa";
$replacement "AAA";
$pattern_encoded     mb_convert_encoding$pattern,     $file_encoding'UTF-8' );
$replacement_encoded mb_convert_encoding$replacement$file_encoding'UTF-8' );

$result mb_ereg_replace$pattern_encoded$replacement_encodedfile_get_contents('UTF-16LE.txt') );
file_put_contents('UTF-16LE-updated.txt'$result);
?>

Since PHP 5.4, to make uppercase ou lowercase characters, or rewrite some uris, without to take care about initial encoding, the transliteration is easier (and probably the best way): see http://php.net/manual/fr/transliterator.transliterate.php and http://userguide.icu-project.org/transforms/general

For example (with create) (french text: replace all accuentued -éèàîïùç...- chars with ascii chars):
<?php
$transliterator 
Transliterator::create("NFD; [:Nonspacing Mark:] Remove; NFC;");
echo 
$transliterator->transliterate("Héhé, ça marche !");
?>
// Result: « Hehe, ca marche ! »

To rewrite a phrase in URI (with createFromRules):
<?php
$transliterator 
Transliterator::createFromRules("::Latin-ASCII; ::Lower; [^[:L:][:N:]]+ > '-';");
echo 
trim($transliterator->transliterate("Héhé, ça marche !"), '-');
?>
// Result : « hehe-ca-marche »

Notations to reference captures in the replacement string:

<?php

// (1) \\number notation: (1 to 9, not greater than 9)
echo mb_ereg_replace('(\S*) (\S*) (\S*)''\\1 jam, \\2 juice, \\3 squash''apple orange lemon').'<br>'// apple jam, orange juice, lemon squash

// (2) \k<number> notation: (also greater than 9) (also as \k'number')
echo mb_ereg_replace('(\S*) (\S*) (\S*)''\k<1> jam, \k<2> juice, \k<3> squash''apple orange lemon').'<br>'// (same as above)

// (3) \k<word> notation: (also as \k'word')
echo mb_ereg_replace('(?<word1>\S*) (?<word2>\S*) (?<word3>\S*)''\k<word1> jam, \k<word2> juice, \k<word3> squash''apple orange lemon').'<br>'// (same as above)

// Note non-named-subpatterns like "(\S*)" should not be used with named-subpatterns like "(?<word>..)" because non-named-subpatterns cannot be captured when named-subpatterns exist.
