PHP: remove `http://` from link title

Question

I have a string that looks like:

$string = \'http://google.com\';

How can I remove the http:

Answer 1

Without using a full blown parser, this may do the trick for most situations...

$str = 'http://google.com';

$regex = '/(?google.com"

It uses a negative lookbehind to make sure there is no href=" or href=' preceding it.

See it on IDEone.

It also takes into account people who delimit their attribute values with '.
