Question

解析错误：第 25 行 C:\xampp\htdocs\tlsproject\server.php 中的语法错误，意外的 '}'

看了一遍又一遍，还是没找到错误

<?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);

错误在这里兄弟，大括号后的分号（;）...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")};改成这个if(empty($username)) {array_push($errors, "Username is required");}&nbsp; if(empty($email)) {array_push($errors, "Email is required");}&nbsp; if(empty($password_1)) {array_push($errors, "Password is required");}&nbsp; if($password_1 != $password_2) {array_push($errors, "Passwords do not match");}
