FILTER_VALIDATE_EMAIL on localhost emails will fail except when
used in conjunction with a subdomain such as www.localhost
FYI Sub domains generally are setup outside of the scope of php configurations.
Using the following code:
<?php
$email = "user@localhost";
echo "PHP Version: ".phpversion().'<br>';
if(filter_var($email, FILTER_VALIDATE_EMAIL)){
echo $email.'<br>';
var_dump(filter_var($email, FILTER_VALIDATE_EMAIL));
}else{
var_dump(filter_var($email, FILTER_VALIDATE_EMAIL));
}
?>
Returns:
PHP Version: 5.5.29 //On MY server
bool(false)
While the following code:
<?php
$email = "user@www.localhost"; //Note the added subdomain www
echo "PHP Version: ".phpversion().'<br>';
if(filter_var($email, FILTER_VALIDATE_EMAIL)){
echo $email.'<br>';
var_dump(filter_var($email, FILTER_VALIDATE_EMAIL));
}else{
var_dump(filter_var($email, FILTER_VALIDATE_EMAIL));
}
?>
Returns:
PHP Version: 5.5.29 //On MY server
user@www.localhost
string(18) "user@www.localhost"
