Email format validation

[achintha]

Hi, I need simple function to validate email address format.

 

I have found follwoing function form google.

 

function isemail($email){
return (bool)ereg("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email);
}

 

It's working fine with php < 5.2. But when I'm using with PHP 5.3

is says

Deprecated: Function ereg() is deprecated in C:\wamp\www\*******\includes\functions.php on line 28

 

Is any solution to this without error disable?

 

Thanks

You can use filter_var for this, with the FILTER_VALIDATE_EMAIL filter. Make sure you check out the types of filters as well though.

 

If you want a more portable solution though, this article from Linux Journal is a good read.

ProjectFear's solution is fine, but with respect to the error, you should be using preg_match() instead of ereg().
