Question

I’ve got a PHP warning message below

Warning: preg_replace() [function.preg-replace]: Compilation failed:
POSIX collating elements are not supported at offset 71 in
**/bbcode.php on line 244

here is in line 244 of bbcode.php

$config['text'] = preg_replace('#(^|[ \t\r\n"“\'])(?i)\b((?:[a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:\'".,<>?«»“”‘’]))#ui', '$1[url]$2[/url]', $config['text']);

Any suggestion to avoid this warning ?
(without editing anything in server config)

I use
PHP Version 5.2.17 and Apache 2.0

Thanks in Advanced.

Apparently, it’s assuming you meant this sequence:

[.]|[a-z0-9.\-]+[.]

…as a collating element (ref) because of the [. and .]. Try using \. to escape the dots instead of [.].
