Just experimented with this regex

if ( '/www\.|http:|https:\/\/[a-z0-9_]+([\-\.]{1}[a-z_0-9]+)*\.[_a-z]{2,5}'.'((:[0-9]{1,5})?\/.*)?$/i' $value)){
$result->invalidate( $tag, “Avoid URLs & Links” );

and got PHP Parse error: syntax error, unexpected ‘$value’ (T_VARIABLE)

Will keep digging but some help would be greatly appreciated.
