Is there a php library for email address validation?

How I can write php script that test e-mail address is input correctly and verify that the input begins with a series of character followed by the @ character, another series of character and a final series of characters.

The filter_var() function, using the FILTER_VALIDATE_EMAIL filter, should do exactly what you want -- no need to re-invent the wheel ;-)

Use the PHP function filter_var() with the FILTER_VALIDATE_EMAIL flag to validate the email address:

$emailValid = filter_var($email, FILTER_VALIDATE_EMAIL);

if($emailValid) {
  echo "Email is valid";
} else {
  echo "Email is INVALID";
}

I mostly use filter_var for this, but a fellow github'r notified me that this function is flawed.

He recommended to use the rather more complex validator at http://www.dominicsayers.com/isemail/.

Good luck!

if(preg_match("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$",$email){
$inputcorrectly = true; // Or whatever
}

-1: Don't use regular expressions to validate email addresses. The RFC email syntax is way to complicated for a regular expression to handle properly. – Andrew Moore Mar 12 '11 at 21:33

@AndrewMoore: You do realize that FILTER_VALIDATE_EMAIL uses a regex? – mario Mar 12 '11 at 21:48
