Hi. I have problem with preg_replace_callback. It seems that my pattern is bad, but I can't find any error. Pattern : \[\s*((\d|\w|_)+)\s*\] this pattern is intended to find strings like "[field]", "[ fi12_eld]"... but every time I get warning message "Warning: preg_replace_callback(): Delimiter must not be alphanumeric or backslash in test.php on line 100"

$pattern= "%\[[\s\w]+\]%";
