Talking I'm a nitpicker; Coding mistake in article 106

In this article it has an example of an e-mail validator.
PHP Code:
<?php 

function validateEmail($email

return 
ereg("^[a-zA-Z]+@[a-zA-Z]+\.[a-zA-Z]+$"$email); 


echo 
validateEmail("mitchell@devarticles.com"); 

?>

That's bad code! What if someone has a number in their e-mail adress? Or an underscore? It would say their e-mail is invalid. I hope no one used this. Here's the real code:
PHP Code:
<?php 

function validateEmail($email

return 
ereg("^[a-zA-Z0-9_]+@[a-zA-Z0-9_]+\.[a-zA-Z0-9_]+$"$email); 


echo 
validateEmail("mitchell@devarticles.com"); 

?>


I hope this isn't a waste of time, as in someone pointed this out already.

BTW: Mytch, you're doing a great job with the site

Hey,
Thanks for pointing that out, but the whole point of that was to get the readers familiar with regexp's.... not to actually validate ALL email addresses...it was to show how patterns work, but thanks for picking it out anyway.

If you really want to get picky, you can download php classes, which validate email addresses, and they work really well, if you want to validate emails, i sugest that you look for one of these classes, their really good
