[snip] I need to replace all the numbers of a credit card except for the last 4 with an 'X' ... can't seem to locate the string function for this... can someone point me in the right direction here to what php item i should be using.

<not-too-serious> wtf :-), I can't find any particular mention of his problem on that page (and I know how to use the CTRL+f keycombo in firefox, thanks for asking :-). regardless of whether ereg_replace() would satisfy his needs pointing him at that page without explaination is a bit stupid - the guy obviously doesn't have even half a clue with regards to string manipulation - therefore I think its safe to assume that regexps are a bit out of his league. but then again if he is working with (_other_peoples_) creditcard numbers he should probably: a, know this shit. or b, be capable of finding the answer in the manual. n'est pas? anyway I had fun remembering exactly what ROFLMMFAO meant :-), and the tinge of RTFM at Joe was probably justified - and even if it wasn't I condone it :-) is it fair game to throw someone an RTFM after you have helped them? </not-too-serious>
