Re: [PHP] Replace credit card numbers with X ???
In addition to what was mentioned already, using ereg_replace, if you're pulling the CC# string out of a database of off of some POST data or something, just use a substr() function to pull the last 4 digits and prepend a bunch of X's. $ccnum = 342342522342342; # fake CC #, prob not even correct # of digits :) $maskedccnum = XXX . substr($ccnum,strlen($ccnum)-5,4); If you're trying to do it in a form, realtime as the user enters it, you'd have to use some funky javascript or do something with a password form type or something. But sounds like you want it like when you display an invoice afterwards or display a Would you like to use this CC that's already on file? type thing without exposing the whole CC#. -TG = = = Original message = = = Hello, 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.

[/snip] ROFLMMFAO! It's all been discussed before Joe! http://www.php.net/ereg_replace 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 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
