下载 zip 文件 php

Question

所以我一直在尝试从我的 WAMP 服务器创建和下载一个 .zip 文件，以便在我正在处理的私有开发服务器上使用，并且在尝试下载我的 .zip 文件时似乎遇到了一些重大问题已经创造出来了。

代码似乎按预期工作。它查看包含我要下载的文件的文件夹，并将它们添加到我的拉链类使用的数组中（靠近底部的函数调用）。

当我运行此代码时，会在服务器上创建 .zip 文件；我可以看到它在那里，打开它，看到文件已添加到 .zip 中。我也可以将压缩文件夹从我的本地 wamp 服务器中拖出来，然后从我的客户端机器中提取出来。 问题是当我尝试下载压缩文件时。它似乎下载了文件，但是当我打开它时，会出现一个 Windows 框，上面写着“Windows 无法打开文件夹，压缩（压缩）文件夹 /path&name/ 无效”，但它在服务器端运行良好。

我也尝试使用此方案来下载和查看单个文件（非压缩文件），它们总是以随机文本的形式出现，这让我相信它与从服务器向服务器提供下载有关客户端机器。

我也尝试在我的实时服务器上运行此代码。尝试查看时也会发生同样的事情，除了（在 chrome 中）一条消息说“/filename/ 不经常下载并且可能很危险”。

我已经检查了 stackoverflow 上的各种帖子以获取解决方案，但似乎没有帮助。

<?php

require_once 'zipper.php';
$dir_path = "files/";

$arrFiles = array(); //Array Of files to be compressed into zip

if(is_dir($dir_path)){
    $files = scandir($dir_path); //create and array that stores all dir files.directories including '.' and '..'
    foreach($files as $newFile){ //Loop through the files
        if($newFile != '.' && $newFile != '..'){ //If the current found is NOT . or ..
            echo "$newFile<br>";
            $newFile = $dir_path . $newFile; 
            $arrFiles[] = $newFile; //add to the array of files to compress/zip
        }
    }
}

//print_r($dir_path."name.zip");

$zipper = new Zipper; //create the zipper object (contains functions for preparing the .ZIP)
$zipper->add($arrFiles); //add files to Zipper ZIP array

$filename = "myFile.zip";
$filepath = $dir_path.$filename; //Path to the new .zip with the ZIP name included in the path
echo $filepath;
echo "<br>";

$zipper->store($filepath); //create the ZIP & store for download

header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Cache-Control: private",false);
    header("Content-Type: application/zip");
    header("Content-Disposition: attachment; 
    filename=".basename($filepath).";" );
    header("Content-Transfer-Encoding: binary");
    header("Content-Length: ".filesize($filepath));
    readfile("$filepath");
?>

下面是我使用的“zipper.php”文件。

<?php
class Zipper{
private $_files = array(), $_zip;

public function __construct(){
    $this->_zip = new ZipArchive;
}

public function add($input){
    if(is_array($input)){
        $this->_files = array_merge($this->_files, $input);
    }else{
        $this->_files[] = $input;
    }
}

public function store($location = null){ //used for storing the files added from the directory
    if(count($this->_files) && $location){
        foreach($this->_files as $index => $file){
            if(!file_exists($file)){
                unset($this->_files[$index]);
            }
            elseif(preg_match('/.zip$/', $file)){ //if the file was already compressed once, remove it from the array of files to zip
                unset($this->_files[$index]);
            }
        }
        print_r($this->_files);
        if($this->_zip->open($location, file_exists($location) ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE)){ //create the .ZIP; if it exists overwrite, else create it

            foreach($this->_files as $file){
                $this->_zip->addFile($file, $file); //for each file in our array add it to the zip
            }

            $this->_zip->close(); //close the zip once completed
        }
    }
}   
}

任何帮助将不胜感激。
