Question

我有这段代码，但它不断下载dashboard.php而不是../config.php

<?php
$filename = "../config.php";
function forceDownLoad($filename){

    header("Pragma: public");
    header("Expires: 0"); // set expiration time
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");
    header("Content-Disposition: attachment; filename=".basename($filename).";");
    header("Content-Transfer-Encoding: binary");
    header("Content-Length: ".filesize($filename));

    @readfile($filename);
    exit(0);
}
forceDownLoad();
?>

为什么要下载dashboard.php？我告诉他下载config.php并继续下载dashboard.php !!

Answer 1

您的功能需要参数$filename。您运行该函数时不会为其提供所需的参数（forceDownload();），这会使您的函数$fileName中出现NULL。因此，它只是抓住你的网站的根并下载它。如果你有PHP错误，你会看到函数调用中缺少参数的通知。

请改为尝试：

forceDownload($fileName);

下载config.php
