[SOLVED] Call a function while using preg_replace is it posible?

[thehigherentity]

Im trying to update my BBCode function so it will check links and emails have the current beginnings eg mailto:, http:// etc

What I would like to know is how i can add a function into the following so the $1 is checked my my fix_url() function.

 

$str = ' My wbsite '; // my link

$str = preg_replace('/\[url\=(.*?)\](.*?)\[\/url\]/is', '<a href="$1">$2</a>', $str);

 

I have tried changing the code to the following and many versions of it with no luck!

 

$str = ' My wbsite '; // my link

$str = preg_replace('/\[url\=(.*?)\](.*?)\[\/url\]/is', '<a href="'.fix_url('$1').'">$2</a>', $str);

 

If It cant be done this way could someone please point me in the right direction to another way I could do the same type of thing.

 

Thanks in advance

It's done by this function.  There's some examples in the comments on that page.
