PHP Validate Email

Introduction

In a lot of projects you need to validate the emails given by the user. You should make sure the email address has a correct format.

For example user shouldn’t give you fakeemail.com  because this is not an email.

Validate Emails in PHP

There are 2 ways to validate the emails in php:

1- using regular expression

To review how to use regular expressions in php check PHP Regular Expressions.

2- using filters

The second solution is much easier and is the preferred way

Php has a lot of filters that you can validate and sanitize data with. In order to use them we need to use the function filter_var

It takes the value as the first argument and the filter as the second argument

The filter for validating emails is FILTER_VALIDATE_EMAIL

So let’s do it

$email = "test@example.com";
if (!filter_var($email,FILTER_VALIDATE_EMAIL)) {
   echo 'invalid email';
} else {
   echo 'email is correct';
}
// email is correct

And with invalid emails:

$email = "testexample.com";
if (!filter_var($email,FILTER_VALIDATE_EMAIL)) {
   echo 'invalid email';
} else {
   echo 'email is correct';
}
// invalid email
