Email Validation

[siri]

he following code snippet always displays invalid.Here is the code snippet I used for email Validation:if(isset($_POST['submit'])){if(!eregi('^[a-zA-Z0-9-\_.]+@[a-zA-Z0-9-\_.]+\.[a-zA-Z0-9.]{2,5}$',$email)){$msg="Invalid";}else{$msg="Valid";}}Please let me know where exactly I am going wrong

I just did some Googling and found a simpler Reg Ex syntax:

^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$

Matches: joe@aol.com|||joe@wrox.co.uk|||joe@domain.infoNon-Matches: a@b|||notanemail|||joe@@.Try that

It's not working .Can anyone tell me what's the mistake in my code

Try just using ereg instead of eregi. Encapsulation wont matter in an email input. Try outputting the answer in print so you see what your dealing with.

The pattern Xenon posted is not completely accurate, for example it incorrectly matches this:.......@........--Here is a discussion about validating email addresses in PHP4:http://www.zend.com/zend/spotlight/ev12apr.phpThis is the pattern they use:

^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$
