I have a class that uses PHP's ereg() which is deprecated. Looking on PHP.net I thought I could just get away and change to preg_match()

Ama normal ifadeler hataları almak ya da başarısız!

İşte iki örnek:

function input_login() {
    if (ereg("[^-_@\.A-Za-z0-9]", $input_value)) { // WORKS
    // if (preg_match("[^-_@\.A-Za-z0-9]", $input_value)) { // FAILS
        echo "is NOT alphanumeric with characters - _ @ . allowed";
    }
}

// validate email
function validate_email($email) {
    // return eregi("^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$", $email); // FAILS
}
