我的网页收到致命错误输出。这是错误：

致命错误：/Users/aaronwilson/Desktop/testing_server/ATOM_CMS/config/setup.php:14 中的消息 'SQLSTATE[HY000] [2005] Unknown MySQL server host '$host' (20)' 中未捕获的异常 'PDOException' 堆栈跟踪：#0 /Users/aaronwilson/Desktop/testing_server/ATOM_CMS/config/setup.php(14): PDO->__construct('mysql:host=$hos...', 'atomcmsadmin', ' ** ') #1 /Users/aaronwilson/Desktop/testing_server/ATOM_CMS/config/setup.php(22): dbConnect('atomcmsadmin', ' ** ', 'localhost', 'Atom_CMS') #2 /Users/aaronwilson/Desktop/ testing_server/ATOM_CMS/index.php(2): include('/Users/aaronwil...') #3 {main} 在第 14 行的 /Users/aaronwilson/Desktop/testing_server/ATOM_CMS/config/setup.php 中抛出

这是在我的 Setup.php 页面上触发错误的代码：

<?php ## Setup Document

// host(or location of the database), username, password, database name
//Variables for connecting to your database.
//These variable values come from your hosting account.

error_reporting(E_ALL);
ini_set('display_errors', 1);
require('functions/sandbox.php');

$host = "localhost";
$user = "atomcmsadmin";
$pass = "*******";
$dbname = "Atom_CMS";

//Connecting to your database

function dbConnect($user, $pass, $host, $dbname) {
$dbc = new PDO('mysql:host=$host;dbname=$dbname', $user, $pass);

try {
    global $dbc;
    }
catch (PDOException $e) {
    echo $e->getMessage();
}
}
if (dbConnect($user, $pass, $host, $dbname)) {
print('worked');
}

if ($_GET ['page'] == '') {
$pg = 'home';} 
else {
$pg = $_GET ['page']; }
$page_title = get_title($dbc, $pg);
?>

任何建议，将不胜感激.. ：）

在这一行：

$dbc = new PDO('mysql:host=$host;dbname=$dbname', $user, $pass);

您使用了单引号。PHP 不会扩展使用单引号的字符串中的变量，因此 PDO 将主机名视为$host.

尝试

$dbc = new PDO("mysql:host=$host;dbname=$dbname", $user, $pass);
               ^                               ^ // note double quotes.
