Thank that was very helpful. your site made it to my favorite list.

array() in $pattern doesn't work here

Nice tool, good job :) One small remark though. If you try to use backreference it wont work as you'd expect, here is the code generated for these values: $pattern => /the (dog|rat|duck) is ill/ $replacement => A \${1} is running $subject => the dog is ill preg_replace('/the (dog|rat|duck) is ill/', 'A \\${1} is running', 'the dog is ill', -1, $count); It fails because the $replacement (i.e 'A \\${1} is running') is set between simple quotes and not double quotes, also because of the backslash added.

@butzi: Thank you. You are right. Works now perfect.

@Mira: Please take a look at the manual. The $pattern ist required to be encapsulated in some special characters (mostly @ or / is used). Anyway else you get the error message.

Great Tool But with: array('~([0-9]{4})_([0-9]{2})_([0-9]{2})__?([0-9]{2})_([0-9]{2})_([0-9]{2,3})(.*)~','~([0-9]{4})-([0-9]{2})-([0-9]{2}) ?([0-9]{2})[.]([0-9]{2})[.]([0-9]{2,3})(.*)~') I get ERROR: Delimiter must not be alphanumeric or backslash It comes from the {2,3} parts. About me this would be correct. Tested in real php. There no error happens. Mira

Very clean and clear website and no advertisement, nice! And thanks for supporting HTML in expressions, well done!
