Summary: Metacharacter \d in a regexp causes an error on some
Russian letters
-Status: Open
+Status: Bogus
Type: Bug
Package: *Regular Expressions
Operating System: Windows
PHP Version: 5.3.2
New Comment:
This is an encoding issue, rather than a bug in PHP itself: by
default, preg_match() works like most things in PHP and just treats
strings as a series of bytes. If ÐаÑилий is encoded in UTF-16,
there are multiple bytes in the range that are digits in ASCII, so
\d matches them.
preg_match() does have support for Unicode text when it's encoded
as UTF-8 via the /u modifier, so the right way to handle this would
be using iconv() or mb_convert_encoding() to convert the string to
UTF-8, then using a regex like
"/[\d...@\#\%\$\^&*\(\)\~\=\/\|\"\'\?\:\;\/]+/u" to force UTF-8
mode.

Description:
------------
Metacharacter \d in a regular expression causes an error on some Russian
letters
on OS Windows.
Example script:
$user_name_ru = "ÐаÑилий";
$regexp = "/[\d...@\#\%\$\^&*\(\)\~\=\/\|\"\'\?\:\;\/]+/";
if( preg_match( $regexp,$user_name_ru ) ) {
echo 'ERR';
} else {
echo 'OK';
}
preg_match() return true if word contains one or more characters 'й',
'г', 'в'.
If to delete metacharacter '\d' preg_match() returns false. If you are
using
php version 5.2.13 all works correctly.
