PHP5 Email Validation

By Bill on February 10, 2009 in PHP

In prior version of PHP you had to use some regex solution to validate an email address, now in PHP5 it’s as simple as:

function isValidEmail($email){
 return filter_var(filter_var($email, FILTER_SANITIZE_EMAIL), FILTER_VALIDATE_EMAIL);
}

if(isValidEmail('email@domain.com')){
//valid
} else {
//not valid
}

function isValidEmail($email){

return filter_var(filter_var($email, FILTER_SANITIZE_EMAIL), FILTER_VALIDATE_EMAIL);

}

if(isValidEmail('[email protected]')){

//valid

} else {

//not valid

}

I’ve been using PHP5 ever since it was released but didn’t look into the PECL Filter extension until recently. Pretty handy.

Please note that I also added the FILTER_SANITIZE_EMAIL filter which removes all illegal e-mail characters from a string. This is not needed if you only want to validate and not clean the input. 🙂
