regular expressions - amending urls

[chriso20]

Hey,

 

Quick question -

 

How can i preg_replace (or whatever i need) these strings:

 

<a href="http://www.google.com">

<a href='www.anothersite.co.uk'>

<a href=whatever.net>

 

so they're replaced with:

 

<a href="mysite.com?url=http://www.google.com">

<a href="mysite.com?url=http://www.anothersite.co.uk">

<a href="mysite.com?url=http://www.whatever.net">

 

 

Thanks in advance!

As long as they are always <a href=  a simple str_replace will work:

 

$string = '<a href="http://www.site.com">Site.com</a>';
$string = str_replace('<a href="', '<a href="http://www.mysite.com/?url=', $string); 

echo $string;
