[RESOLVED] regex url matching help

[jasondavis]

I want to have a regex code that will detect an external link that users post on my site and make it redirect through a redirect page, can someone give me a good regex code to match any possible URL variation

example of what should be match

<a href="http://www.url.com">text link</a>

will turn into

<a href="http://www.mydomain.com/p=http://www.url.com">text link</a>

and

<a href="http://www.url.com" target="_blank" class="bluelinkbold">text link</a>

will turn into

<a href="http://www.mydomain.com/p=http://www.url.com" target="_blank" class="bluelinkbold">text link</a>

and

<a href="http://www.url.com" target="_blank" class="bluelinkbold"><img src="path"></a>

will turn into

<a href="http://www.mydomain.com/p=http://www.url.com" target="_blank" class="bluelinkbold"><img src="path"></a>

Any help appreciated

Try this one:

https?://([-\w.]+)+(:\d+)?(/([\w/_.]*(\?\S+)?)?)?

hope this helps,

$str = <-- your html -->
$pattern = "#<a href=\"http://((.+?))\"#";

$output = preg_replace($pattern,'<a href="http://$1/p=http://www.url.com"',$str);

Best regards,
