PHP : How To Validating Email Address

On this occasion, I will give some examples to validate email address with php.
Example 1

$email = $_POST['email_address'];
filter_var($email, FILTER_VALIDATE_EMAIL);

This function will returns the filtered data, or FALSE if the filter fails.

Example 2

<?php
var_dump(filter_var('bob@example.com', FILTER_VALIDATE_EMAIL));
var_dump(filter_var('http://example.com', FILTER_VALIDATE_URL, FILTER_FLAG_PATH_REQUIRED));
?>

The above example will output:

string(15) "bob@example.com"
bool(false)

Example 3

<?php
$email = $_POST['email_address'];
$valid_email = filter_var($email, FILTER_VALIDATE_EMAIL);
if($valid_email===false){
// TODO - When email address is invalid
} else {
// TODO - When email address is valid
}
?>
