Good Email Validator for PHP

Anon

if(!(ereg("^{[a-zA-Z0-9]+@[a-zA-Z0-9]+.[a-zA-Z0-9]+",} $emailAddress)))
{
print("<center>ERROR: Missing Information</center> Please hit your\"back\" button and provide a valid \"Email Address\" in the form of someone@somewhere.some_extension, containing only numbers or letters.");
$errorOn = 1;
}

if(!(ereg("^{[a-zA-Z0-9]+@[a-zA-Z0-9]+.[a-zA-Z0-9]+$",} $emailAddress)))

print("invalid email... yadda... ");

One amendment: placing the $ on the end. After much testing, this is pretty foolproff from what I can see, and surprisingly simple compared to some of the validators i've seen here.

ok, that's the bad version and now you are looking for a good version I guess?

It's simple because it is not complete. :-)
the part before the @ can hold more than just numbers and letters, and the toplevel domain must be at least two characters.

if(!(ereg("^{[-.a-zA-Z0-9]+@[-.a-zA-Z0-9]+.[a-zA-Z]{2,}$",} $emailAddress)))

OK, Vince. If you know something, why intentionally waste the time of everyone that clicks on these messages to get some info? Are you some kind of smart ass?
:-)

Well, this has solved part of the problem. Come to think of it, there are dashes and dots in many mail server names.

So just what characters are allowed. Why don't you let us all know.

I understand that you are slightly miffed at my response, and my reply probably wasn't the most polite one I ever made, but then again your post was just a regexp, which does not explain a lot.

From a timewasting point of view, you are wasting much more time than I.

If you did a search before you posted (or even before you began working on your regexp) you would have found threads like this:

and this

and code snippets like this:

And what's more, if you start to design a regexp to verify email adresses I would assume that you first get more information about which characters are allowed inside an email address, instead of taking just a few email adresses that you know are valid.

so you see, I'm not such a smartass, I just take more time to look for information than you.

1) You are a smartass.

2) How do you know how much time I take to look for information? Talk about not doing research before you put your boney fingers on your keyboard to tap out your tripe. Do you have some sort of magely cyber-tracking wizbang-em-up gadget in your pocket that automatically explodes into a post-modern all-in-one super-probe to do everything but wash my mother's underwear?

3) I do sincerely hope you feel better about yourself now Vince old boy. You might have noticed i didn't even bother to respond to your smartest post, which was nothing if not a galactic waste of time for everyone (who isn't rapturously inveigled by the thought of joining in your obvious propensity for computerized circle jerking).

4) What's the matter, can't handle your woman? I think you better learn before you really waste someone's time. Fortunately for me, I love twerps like you. I don't even have to take the time you do and you're still a two-faced, passive-aggressive, subversively sadistic, fascist pharisee of a little b*tch on a crusade to pump out your endless turdlets of technobabble into every hole you can jab your filthy little digits into all in a pitifully ineffectual attempt to stay your blatant and torturously nebular self-loathing...

Enjoie!

lol

well at least you are in touch with your anger!

and all that because you were too lazy to do proper research... sad really.

Ahhhhhhhhhhhhhhhhh.

Yes, yet more assumptions from Mr. Gadget. How refreshing is your dipsh%t mentality in a world full of shallow techno-droids. What a wonder of information-assimilation you are. Say, you might want to take a fresh gander at that little manual you chucked in the dustbin amidst such a fleeting moment of arrogance that you didn't even realize your ever-taunting lack of appreciation for yourself and life was putting you in a very clever and perpetual state of insateable self-eulogy such that the motion of your hand was but a sheer act of having to know there was nothing in that manual you didn't already know.

So you see, Vince, mon ami, what is sad? It is the fact that you just read more truth about yourself in my last post than you'll probably ever have the fortune of stumbling across again in all your days of mediocrity, and you still can't do one thing to impress me despite all your simple ego-boost.

The truth can not be undone, contrary to every modern convention. It can only be tinkered with and wire-wrapped until it's a really-super-big-assed bomb just sittin' there in your lap.

So go chase down that dustman and beg him for that manual, cause your all-in-one super-probe is a little outa your league old friend.

Sure Vince. I'm so in touch with my anger you can't even hide yours under all your Himalayan claptrap of coy "I'm a great guy" crap.

Love yah!
