Ok I am doing some ubb code for a forum I am getting this error:
Warning: Unknown modifier '/' in file.php on line 142
Line 142 is:
$msg = preg_replace("/[url](http://)?(.*?)[/url]/si", "<a href='12' target='_blank'>2</a>", $msg);
Any ideas what this means?
Ok I fixed the warning error by changing the line to this:
$msg = preg_replace("#/[url](http://)?(.*?)[/url]/si#", "<a href='12' target='_blank'>2</a>", $msg);
But now its not replacing it like it should. Any ideas?
You are using the slash as the delimiter for your regex. The engine will look for the first slash to end the expression.
Either choose a delimter that is not contained within your expression or escape the slashes.
Thanks andreasfriedrich I just figured that out now to tackle the next issue. Thanks again for the help.
Perhaps you would like to post an example of a string you want to perform the replacement on? That would be helpful to test your expression.
BTW I didnīt see that you already solved the first problem when I posted my reply and was just too lazy to edit it.
