You can get all the terms into an array using preg_match_all:-
$str = "UNAVAILABLE More Info AVAILABLE More Info";
$regExp = "/(?:UN)?AVAILABLE|More Info/";
preg_match_all($regExp, $str, $regs);
$regs[0] will contain the matched terms - you should then be able to use
array functions to do whatever else you need to do - counting, positions,
etc
