Digg mb_ereg_replace
Replace regular expression with multibyte support
(PHP 4 >= 4.2.0, PHP 5)
mb_ereg_replace() scans
string for matches to
pattern, then replaces the matched text
with replacement and returns the result
string or
Matching condition can be set by option
parameter. If The internal encoding or the character encoding specified in mb_regex_encoding() will be used as character encoding. See also: mb_regex_encoding(), mb_eregi_replace(). Code Examples / Notes » mb_ereg_replacesqueegee
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.

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.

Are you looking for htmlentities() for multibyte strings? This might help you - it just replace <, >, ", ' /** * 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('<', '>', '"', '\''); $replacement = array('<', '>', '"', '''); for ($i=0; $i<sizeof($pattern); $i++) { $str = mb_ereg_replace($pattern[$i], $replacement[$i], $str); } return $str; } faxe
A simple mb_str_ireplace() implementation - a faster (?) replacement for non-regexp multi-byte string replacement: [code] function mb_str_ireplace($co, $naCo, $wCzym) { $wCzymM = mb_strtolower($wCzym); $coM = mb_strtolower($co); $offset = 0; while(($poz = mb_strpos($wCzymM, $coM, $offset)) !== false) { $offset = $poz + mb_strlen($naCo); $wCzym = mb_substr($wCzym, 0, $poz). $naCo .mb_substr($wCzym, $poz+mb_strlen($co)); $wCzymM = mb_strtolower($wCzym); } return $wCzym; }[/code] 04-dec-2006 04:36
'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.
