How to fix an error in the authorization file?

Question

PHP

Where is the mistake? Please explain, I'm dumb.

<?php 



    $host = "localhost";
    $admin = "root";
    $password = "root";
    $database = "bigrtm";

    $login = $_POST['login'];
    $name = $_POST['name'];
    $email = $_POST['email'];
    $psw = $_POST['psw'];
    $tpwd = $_POST['tpwd'];
    $info = $_POST['info'];


?>




<?php 

if (strlen($login) > 80){
    die();
} 

if (strlen($login) < 7){
    die();
} 

if (strlen($name) > 50){
    die();
} 

if (strlen($name) < 3){
    die();
} 
if (strlen($email) > 400){

    die();
} 

if (strlen($email) < 5){
    die();
} 

if (strlen($psw) > 32){
    die();
} 

if (strlen($tpwd) > 32){
    die(); 
} 

if (strlen($info) > 1000){
    die();
} 

if ($psw != $tpwd ){
    die();
}
?>

<?php 
    $hash_md = md5($psw);
    $date_r = date("Y года, M d, в H:i");
    $date_int = date("YmdHis");
    $cnnect_database0 = new mysqli($host, $admin, $password, $database);
    $query_database0 = $cnnect_database0->query("INSERT INTO `users` (`login`, `name`, `email`, `password`, `info`, `date`, ) VALUES('$login', '$name', '$email', '$hash_md', '$info') ");
?>


<?php 

mysqli_connect_error();

setcookie('login', $login, time() + 3600 * 24 * 30, "/");
setcookie('name', $name, time() + 3600 * 24 * 30, "/");
setcookie('pass', $psw, time() + 3600 * 24 * 30, "/");
?>

Answer 1

type the text of the error in the browser and get about a million responses

Answer 2

Apparently you are trying to set cookie headers at the moment when the server response body has already been formed and, accordingly, the headers have also already been formed.
