I didn't fully test this; but it should get you started.

$types= array('http', 'ftp', 'https', 'mms', 'irc');

$pattern= "%<a\040href\040*=['"]$types://((www.)*[\w/\.]+)['"]>.+</a>%i"; // the "i" makes it non case sensitive

if(preg_match($pattern, $URL_str, $match)){

$URL= match[1];
}

else{

User did not enter a complete link; do the simple thing
}
