It'll be easier if you catch the matches with preg_match and assemble
what you need out of that:

http://php.net/manual/en/function.preg-match.php

Note that square brackets will need to be escaped as those signify
character groups in a regex.

$regex = '/\[(.*?)\]/';

preg_match($regex,'[url=Name_of_URL]Name_of_URL[/url]',$matches);

echo $matches[1]; prints Name of URL
