Doesn't alert the user?

Question

PHP

Does not authorize the user on the site. I'm doing a very simple blog (just for myself). When I click login, I get a white screen. Here is the code. Doesn't see any errors.

<?php 

        $data = $_POST;

        if (isset($data["do_login"])) {
          $errors = array();

          $users_log = mysqli_query($db_connect, "SELECT * FROM `users` WHERE `name` = '" . $data["login"] . "'");

          if ( $data['login'] == $users_log["name"]) {
            if (passwor_verify($data['password'], $users_log["pass"]) ) {
              # code...
            } else {
              $errors[] = "Пароль не правильний";
            }
          } else {
            $errors[] = "Користувач з таким именем не знайдений";
          }
          echo "<div style='color:red;'>" .	array_shift($errors) . "</div> <hr>";
        }

        ?>

Good afternoon.
You already ask the second question and write that there are no errors. But you get a white screen.
So maybe you should look into the server logs, the browser console, turn on error output to the browser? Raise, finally, the level of displayed errors.
It also does not hurt to arrange checks in the code.
There, you look, and the error will come out and you will figure out your problem yourself ...
ps
You can start with what is wrong here.

$data = $_POST;
        if (isset($data["do_login"])) {

It would be more correct

if (isset($_POST)) {
    $data = $_POST;
    // остальной Ваш код
}

I changed your code a bit and tried to run it.

$users_log = mysqli_query($mysqli, "SELECT * FROM `users` WHERE `username` = 'administrator'");

if ($users_log["username"] == 'administrator') {
  if (passwor_verify($data['password'], $users_log["pass"]) ) {
  # code...
  } else {
    $errors[] = "Пароль не правильний";
  }
} else {
  $errors[] = "Користувач з таким именем не знайдений";
}
echo "<div style='color:red;'>" .	array_shift($errors) . "</div> <hr>";

And as a result, something appeared that you do not want to adjust in any way!
Here is the documentation , read it and do it right.

Answer 2

Or maybe the data is not the same? MB action is not the same. Or method is not equal to post. And the mb names are specified in the id, and not in the name attributes of the inputs, which also happens <form>...</form>

Answer 3

if (passwor_verify($data['password'], $users_log["pass"]) ) {
              # code...
            }

'passwor_verify' misspelling in function name, password_verify
