Question

以下是我在WAMP 2.5上运行的代码。在MAMP上工作正常，但在WAMP上，它一直给出undefined变量错误。例如，$dbhandle是未定义的错误，因为我已经在第49行之前明确定义了它。我感觉PHP解释器没有按顺序访问文件。它直接读取html和/html之间的内容，而不是从顶部读取。

<?
    ini_set('display_errors',0);
    ini_set('display_startup_errors',0);
    error_reporting(E_ALL);

    include_once 'config.php';
    $username = "";
    $password = "";
    $dbhandle = null;
    $row = null;

    $username = $config['user'];
    $password = $config['password'];
    $hostname = $config['server'];
    $db = $config['db'];
    //connection to the database
    $dbhandle = mysql_connect($hostname, $username, $password)or die(mysql_error($dbhandle));

    $selected = mysql_select_db($db,$dbhandle)or die(mysql_error($dbhandle));

    if(isset($_GET['id']))
    {
        $id = intval($_GET['id']);
        $query = "Delete from posts WHERE sb_id = $id";
        $result = mysql_query($query, $dbhandle) or die(mysql_errno($dbhandle));

        $query = "Delete from comments WHERE post_id = $id";
        $result = mysql_query($query, $dbhandle) or die(mysql_errno($dbhandle));
        header("Location: index.php");
    }
?>
