Could anyone explain to me why this is returning TRUE? There are 7 z's yet it should be returning FALSE because I've set a max limit of 6 in the regex.
preg_match('/z{4,6}/', "zzzzzzz")

That is because your string includes a substring of 4 to 6 'z's. If you want the match to be against your whole string, you have to put in the anchors in your regex.
/^z{4,6}$/
or
/\Az{4,6}\z/

@Chris: to clarify, ^ and $ are start and end of string respectively (or newline if using modifiers but lets not complicate things). So the regex here says "start of string, followed by 4 to 6 z's followed by end of string"
