一遍又一遍地看，但仍然找不到错误

  $errors = array();

Answer 1

错误在这里兄弟，括号后的semicolon(;(...

if(empty($username)) {array_push($errors, "Username is required")};
if(empty($email)) {array_push($errors, "Email is required")};
if(empty($password_1)) {array_push($errors, "Password is required")};
if($password_1 != $password_2) {array_push($errors, "Passwords do not match")};

将其更改为此

if(empty($username)) {array_push($errors, "Username is required");}
  if(empty($email)) {array_push($errors, "Email is required");}
  if(empty($password_1)) {array_push($errors, "Password is required");}
  if($password_1 != $password_2) {array_push($errors, "Passwords do not match");}

<?php
  session_start();
  //initializare variabile
  $username = "";
  $email = "";
  $errors = array();
  //conectare la baza de datefmt_create
  $db = mysqli_connect('localhost','root','','project') or die("Could not connect to database");
  //Inregistrare user
  $username = mysqli_real_escape_string($db, $_POST['username']);
  $email = mysqli_real_escape_string($db, $_POST['email']);
  $password_1 = mysqli_real_escape_string($db, $_POST['password_1']);
  $password_2 = mysqli_real_escape_string($db, $_POST['password_2']);
  //Validare
  if(empty($username)) array_push($errors, "Username is required");
  if(empty($email)) array_push($errors, "Email is required");
  if(empty($password_1)) array_push($errors, "Password is required");
  if($password_1 != $password_2) array_push($errors, "Passwords do not match");
  //Unicitate username
  $user_check_query = "SELECT * FROM user WHERE username = '$username' or email = '$email' LIMIT 1";
  $results = mysqli_query($db, $user_check_query);
  $user = mysqli_fetch_assoc($result);
  if($user)
  {
    if($user['username'] === $username) array_push($errors, "Username already exists");
    if($user['email'] === $email) array_push($errors, "This email is already being used");
  }
  //Inregistrare user
  if(count($errors) == 0){
    $password = md5(password_1); // encriptare parola
    $query = "INSERT INTO user (username, email, password) VALUES ('$username', '$email', '$password')";
    mysqli_query($db,$query);
    $_SESSION['username'] = $username;
    $_SESSION['success'] = "You are now logged in";
    header('location: index.php');
  }

注意无需{}当代码在同一行中，如果语句为
