PHP验证无效

Question

My php code is not working. It is showing wrong messages. For example if I fill the email address longer than 10 characters, then it still shows that my field is empty.

<?php
    $errors = array();

    if (isset($_POST['submit'])) {
        $name  = htmlentities(mysql_real_escape_string($_POST['name']));
        $email = htmlentities(mysql_real_escape_string($_POST['email']));
        $ip    = $_SERVER['REMOTE_ADDR'];

        if (strlen($email) > 10) {
            echo 'ok';  
        } 
        else {
            echo 'empty';
        }
    }
?>

Answer 1

if you want to validate if the email address is 10 or under 10 -> error then u should use

if(strlen($email)<=10) {
echo 'ok';  
} else {
echo 'empty';
}

but there are other email validators that are better

if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
    // invalid emailaddress
}

because what is my email is [e-mail] then it will validate false but if thats my email adress then i have a problem
