regexp with russian lang

Question

I can\'t solve my problem with regexp.

Ok, when i type:

$string = preg_replace(\"#\\[name=([a-zA-Z0-9 .-]+)*]#\",\"$name_start $1 $name_end\",$string         


        

Answer 1

The common unicode script (supported since pcre 3.3) provides a test for the property Cyrillic.

e.g. replace all characters that are neither cyrillic nor (latin) digits:

$string = '1a2b3cйdцeуfкбxюy';
echo preg_replace('/[^0-9\p{Cyrillic}]/u', '*', $string);

You can find the documentation for that feature under http://www.pcre.org/pcre.txt "Unicode character properties".
And you have to specify the PCRE8 flag (u) as described at http://docs.php.net/reference.pcre.pattern.modifiers
