MAMP：PHP 文件中的 HTTP 错误 500

Question

尝试执行 php 文件时，本地 MAMP 服务器上出现 HTTP 错误 500。

我的所有其他页面都会运行，但是这个页面不会运行，所以我想这可能与 php 设置有关？

<?php 

// User.class.php

require_once 'DB.class.php';

class User {

    public $id;
    public $username;
    public $hashedPassword;
    public $email;
    public $joinDate;

    // Takes an associative array with the DB row as an argument.

    function __construct($data) {

        $this->id = (isset($data['id'])) ? $data['id'] : "";
        $this->username = (isset($data['username'])) ? $data['username'] : "";
        $this->hashedPassword = (isset($data['password'])) ? $data['password'] : "";
        $this->email = (isset($data['email'])) ? $data['email'] : "";
        $this->joinDate = (isset($data['join_date'])) ? $data['join_date'] : "";

    }

    public function save($isNewUser = false) {

        $db = new DB();

        // Update already registered user.
        if (!$isNewUser) {

            $data = array(
                "username" => "'$this->username'";
                "password" => "'$this->hashedPassword'";
                "email" => "'$this->email'";
            );

            $db->update($data, 'users', 'id = '.$this->id);

        }

        // Register new user.
        else {

            $data = array(
                "username" => "'$this->username'";
                "password" => "'$this->hashedPassword'";
                "email" => "'$this->email'";
                "join_date" => "'".date("Y-m-d H:i:s", time())."'"
            );

            $this->id = $db->insert($data, 'users');
            $this->joinDate = time();

        }

        return true;    

    }

}

?>

Answer 1

也许是因为数组值以分号结尾，而它应该是逗号：

$data = array(
                "username" => "'$this->username'";
                "password" => "'$this->hashedPassword'";
                "email" => "'$this->email'";
                "join_date" => "'".date("Y-m-d H:i:s", time())."'"
            );

应该是：

$data = array(
                "username" => $this->username,
                "password" => $this->hashedPassword,
                "email" => $this->email,
                "join_date" => date("Y-m-d H:i:s", time())
            );

Answer 2

带有分号的数组应该会导致 PHP 中出现致命错误，而不是 500 内部服务器错误。
