each part of this regex works alone but when i string them together it does not match a url with http or www followed by one of the listed TLDs.

(preg_match('/http\:\/\/(www\.)?[a-z](\.com|\.org|\.net|\.mil|\.edu|\.COM|\.ORG|\.NET|\.MIL|\.EDU)$/', $bandUrl))

    You probably left out the + after [a-z] (which btw is not correct to match all valid URLs). And instead of listing both uppercase and lowercase .TLDs, you could use the /i flag:

    preg_match('/http\:\/\/(www\.)?[a-z]+(\.com|\.org|\.net|\.mil|\.edu$/i',

    Btw, as alternative you could use filter_var($url, FILTER_VALIDATE_URL) for testing.
