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);  $user = mysqli_fetch_assoc($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');  } ?>解析错误：第 25 行 C:\xampp\htdocs\tlsproject\server.php 中的语法错误，意外的 '}'

Answer 1

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");}

  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");}

Answer 2

<?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');

  }

 ?>

注意当代码在 IF 语句所在的同一行时不需要 {}
