How to validate an email address in PHP ?
In this article, we will learn to validate an email with PHP regular expression. We will learn different methods to validate email address in PHP.
Method1
The function preg_match() checks the input matching with patterns using regular expressions.
Example
<?php
function checkemail($str) {
return (!preg_match("/^([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6}$/ix", $str)) ? FALSE : TRUE;
}
if(!checkemail("alex@tutorialspoint.com")){
echo "Invalid email address.";
}
else{
echo "Valid email address.";
}
?>Output
Valid email address.
In the above example PHP preg_match() function has been used to search string for a pattern and PHP ternary operator has been used to return the true or false value based on the preg_match return.
Method 2
We will discuss email validation using filter_var() method.
Example
<?php
$email = "pattrick@tutorialspoint.com";
// Validate email
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo("$email is a valid email address");
}
else{
echo("$email is not a valid email address");
}
?>Output
pattrick@tutorialspoint.com is a valid email address
