Email Address







In this article, we show how to validate an email address using PHP.

This is to make sure that the email that a user enters into an email text box is actually a valid email address.

PHP has a built-in function, filter_var() function, to check for email validation.

PHP Code

The PHP code to validate an email is shown below.

We create a variable named $email. We set to an example email.

We then create an if statement that if the filter_var() function with the $email as one of its parameters is true (not false), then it is a valid email address. Otherwise, it's an invalid email address.

It's really easy to validate an email address in PHP because it has a built-in function that checks for validation.
