You can use some delimiter other than slashes to specify a regex, such as "!/!" to match any slash. Note that I'm using ! instead of / to delimit my regex.

here is many things which are to strips like **slashes /** **dots .** and **comloms :** – user1752627 Feb 20 '13 at 05:51
Use a character class to include or exclude entire ranges of characters, such as `/[^a-zA-Z0-9 ]/` to strip anything but alphanumeric or space. – Ian McMahon Feb 20 '13 at 05:53

Use preg_quote() function to escape regular expression characters try$preg_wurl = '/^'.preg_quote($url, '/').'/i';
