数据库连接问题

Question

我无法连接到我的数据库，我不明白为什么。

我在php检查器中运行我的php没有错误。

我正在观看在线课程并按照信中的说明进行操作，但当我尝试测试并查看它是否有效时，我收到了“http 500错误”。

继承我的PHP：

<?php

//STEP 1. Declare params of user information
$email = htmlentities($_REQUEST["email"]);
$password = htmlentities($_REQUEST["password"]);

$test = "test";

if (empty($email) || empty($password)) {

    $returnArray["status"] = "400";
    $returnArray["message"] = "Missing required information";
    echo json_encode($returnArray);
    return;
    }

//secure password
$salt = openssl_random_pseudo_bytes(20);
$secured_password = sha1($password . $salt);

//build connection
//secure way to build connection
$file = parse_ini_file("../caps.ini");

//store in php var info from ini var
$host = trim($file["dbhost"]);
$user = trim($file["dbuser"]);
$pass = trim($file["dbpass"]);
$name = trim($file["dbname"]);


// include access.php to call func from access.php file 
require("secure/access.php");
$access = new access($host, $user, $pass, $name);
$access->connect();

?>

这是我在文本编辑器中创建的caps.ini文件，我在这里省略了这些信息：

; Connection information
[section]
dbhost = omitted
dbuser = omitted
dbpass = omitted
dbname = omitted

最后这是我的php文件，我引用了我的连接函数：

<?php

//Declare class to access this php file
class access {

    //connection global variables
    var $host = null;
    var $user = null;
    var $pass = null;
    var $name = null;
    var $conn = null;
    var $result = null;

    // constructing class
    function __construct($dbhost, $dbuser, $dbpass, $dbname) {

    $this->host = $dbhost;
    $this->user = $dbuser;
    $this->pass = $dbpass;
    $this->name = $dbname;

    }

    // Connection Function
    public function connect() {

        //establish connection and store it in $conn
        $this->conn = new msqli($this->host, $this->user, $this->pass, $this->name);

        //if error
        if (mysqli_connect_errno()) {
            echo 'Could not connect to database';
        } else {
            echo "Connected";
        }
        //support all languages
        $this->conn->set_charset("utf8");

    }

    //disconnection function
    public function disconnect() {

        if ($this->conn != null) {
        $this->conn->close();
        }

    }


}

这也是我的文件夹结构：

Answer 1

我的假设是围绕msqli与mysqli

的错误

$this->conn = new msqli($this->host, $this->user, $this->pass, $this->name);

应该是

$this->conn = new mysqli($this->host, $this->user, $this->pass, $this->name);
