To highlight words in multi-byte text:

<?php $s = '?????????'; $f = '??'; echo preg_replace('/('.$f.')/iu', '<b>$1</b>', $s); ?>

when trying to find a way to strip newline from a multibyte UTF-8 string i got to this function just to discover later that POSIX don't "do" newline so i can't strip them, examples of what i tried are : \r\n , \\r\\n , (\\r\\n) (\\r|\\n)

and got no result
so since i wanted something like mb_nl2br() that's simple i wrote this little recursive function for UTF-8:

<?php function mb_str_replace($find,$replace,&$str) { $i = mb_strpos($str,$find, 0,"UTF-8"); if ($index===false) {return;} $str = mb_substr($str, 0,$i).$replace.mb_substr($str, $i+mb_strlen($find,"UTF-8"),mb_strlen($str,"UTF-8")); $this->mb_str_replace($find,$replace,$str); } ?>

note: moderate unit tesing was done, changed to other encodings

Transliterator for cyrillic-to-latin letters for UTF chars:

<?php function do_translit($st) { $replacement = array( "??"=>"i","??"=>"c","??"=>"u","??"=>"k","??"=>"e","??"=>"n", "??"=>"g","??"=>"sh","??"=>"sh","??"=>"z","??"=>"x","??"=>"\'", "??"=>"f","??"=>"i","??"=>"v","??"=>"a","??"=>"p","??"=>"r", "??"=>"o","??"=>"l","??"=>"d","??"=>"zh","??"=>"ie","??"=>"e", "??"=>"ya","??"=>"ch","??"=>"c","??"=>"m","??"=>"i","??"=>"t", "??"=>"\'","??"=>"b","??"=>"yu", "??"=>"I","??"=>"C","??"=>"U","??"=>"K","??"=>"E","??"=>"N", "??"=>"G","??"=>"SH","??"=>"SH","??"=>"Z","??"=>"X","??"=>"\'", "??"=>"F","??"=>"I","??"=>"V","??"=>"A","??"=>"P","??"=>"R", "??"=>"O","??"=>"L","??"=>"D","??"=>"ZH","??"=>"IE","??"=>"E", "??"=>"YA","??"=>"CH","??"=>"C","??"=>"M","??"=>"I","??"=>"T", "??"=>"\'","??"=>"B","??"=>"YU", ); foreach($replacement as $i=>$u) { $st = mb_eregi_replace($i,$u,$st); } return $st; } ?>
