email validation

[AV1611]

can anyone improve this?

 

aaa@bbb is valid...

 

  if( !preg_match( "/^([a-zA-Z0-9])+([a-zA-Z0-9\._-])*@([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)+$/", $email))

if (!preg_match('/^[-_a-z0-9\'+*$^&%=~!?{}]++(?:\.[-_a-z0-9\'+*$^&%=~!?{}]+)*+@(??![-.])[-a-z0-9.]+(?<![-.])\.[a-z]{2,6}|\d{1,3}(?:\.\d{1,3}){3})(?::\d++)?$/iD', $email))

 

That should do the trick.  Also, there's an ongoing topic already:  http://www.phpfreaks.com/forums/index.php/topic,192839.0.html
