Question

编辑：已解决

我正在尝试从单独的文件传递一些mysql连接的变量。但是，它们似乎只是以字符串形式出现而不是变量。

connect.php：

<?php
    function connect(){
        require ($_SERVER['DOCUMENT_ROOT'].'/db-connect.php');
        $conn1 = new mysqli($servername, $username, $password, $dbname);
        if ($conn1->connect_error) {
            die("Connection failed: " . $conn1->connect_error);
            }
            echo $conn1->host_info . "\n";
    }
    connect();
?>

DB-connect.php：

<?php
$servername = "localhost";
$username = "-";
$password = "--";
$dbname = "---";
?>

消息传来：

$servername = "localhost"; $username = "-"; $password = "--"; $dbname = "---";Connection failed: Access denied for user '-'@'localhost' (using password: NO)

注释：最后的$ password与db-connect.php文件中的密码不同。这是我第一次尝试时使用的旧密码。此外，用户' - '@'localhost'是旧用户，而不是来自$ username的用户。

请提出任何想法，谢谢？马特

也许这种方式对你来说可能更好。

<?php

require ($_SERVER['DOCUMENT_ROOT'].'/db-connect.php');

   function connect(){

   global $servername, $username, $password, $dbname;

        $conn1 = new mysqli($servername, $username, $password, $dbname);
        if ($conn1->connect_error) {
            die("Connection failed: " . $conn1->connect_error);
            }
            echo $conn1->host_info . "\n";
    }
    connect();

?>

PHP include / require变量未传递
