Regex For Email

[cancer10]

Hi PPL,

I wrote a regex to verify an email address

if(!preg_match("^[a-z0-9]+@{1}[a-z0-9-]+\.{1}[a-z]{2,4}\.?[a-z]{0,2}$",$myemail))
echo "Invalid Email";

Please take a look and tell me if this will work for all type of emails, For example:

abc@domain.co.uk
OR
abc@domain.info
OR
abc@domain.com

and other emails also...


Thanx

I can't seem to get your code to work for abc@domain.info. I want to add that I do not know much about regex or PCRE, but I went to http://regexadvice.com/forums/thread/46502.aspx and found the following code that seems to work for all emails.

<?php
$test='abc@domain.info';
if(preg_match('/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/', 
        $test)) {echo "YES";}
else {echo "NO";}
?>

I altered it just slightly to recognize abc@domain.info. Let me know if you find any email address that does not work for that code.

Thanx mate for your help

Doh! I forgot to make the tiny change to allow abc@domain.info to work. Here is what the code should look like:

<?php
$test='abc@domain.info';
if(preg_match('/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/', 
        $test)) {echo "YES";}
else {echo "NO";}
?>

please disregard my earlier post.
