convert url to links from string except if they are in an attribute of an html tag

Question

I am trying to convert, from a textarea input ($_POST[\'content\']), all urls to link.

$content = preg_replace(\'!(\\s|^)((https?://)+[a-z0-9_./

This has been done hundreds of times over before. On this page either m-buettner and glavić work fine although I like glivic's shorter expression.

Here's a good php resource to do it: http://code.iamcal.com/php/lib_autolink/
