Question

您好我是一个php新手，我目前正在关注如何制作库存管理系统的教程，我仍在登录界面。因为我是php的新手，所以我不太了解它。我希望有专家可以帮我解决这个问题。这是代码

<?php

require_once 'php-action/db_connect.php';

session_start();

$errors = array();

if($_POST) {
    $username = $_POST['username'];
    $password = $_POST['password'];

    if(empty($usernmame) || empty($password)){
        if($username == ""){
            $error[] = "Username is required";
        }

    if($password = ""){
            $error[] = "Password is required";
    }
  }else {
      $sql = "SELECT * FROM users WHERE username = '$username'";
      $result = $connect->query($sql);

      if($result->num_rows == 1){
          $password = md5($password)

          $errors[] = "Username does not exist";
          // exits
          $mainsql = "SELECT * FROM users WHERE username = '$username' AND 
password ='$password";
          $mainResult = $connect->query($mainSql);

          if($mainResult->num_rows == 1){
              $value = $mainResult->fetch_assoc();
              $user_id = $value['user_id'];
            //set session 
            $_SESSION['user_id'] = $user_id;


   header('location:http://localhost/test/stock_system/dashboard.php');
          }  else{
              $errors[] = "incorrect username/password combination";

          }
          }else{
              $errors[] = "Username does not exist";
          }


  } 



}

，错误在此行

$errors[] = "Username does not exist";

如果脚本有点混乱，任何帮助都表示赞赏和抱歉我顺便使用php 5 谢谢

Answer 1

这是语法错误。你错过了一个分号。

      $password = md5($password)  <---  You missed a semicolon here

      $errors[] = "Username does not exist";

如何在第28行的C：\ xampp \ htdocs \“test \ stock_system \ index.php”中解决“解析错误：语法错误，意外'$ errors'（T_VARIABLE）”？
