使用php脚本的压缩/压缩文件夹

有没有办法使用php脚本压缩/压缩服务器中的文件夹到.zip或.rar或任何其他压缩格式，以便根据请求我们可以将文件夹归档，然后给下载链接提前

感谢

Answer 1

下面是一个例子：

<?php 

// Adding files to a .zip file, no zip file exists it creates a new ZIP file 

// increase script timeout value 
ini_set('max_execution_time', 5000); 

// create object 
$zip = new ZipArchive(); 

// open archive 
if ($zip->open('my-archive.zip', ZIPARCHIVE::CREATE) !== TRUE) { 
    die ("Could not open archive"); 
} 

// initialize an iterator 
// pass it the directory to be processed 
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator("themes/")); 

// iterate over the directory 
// add each file found to the archive 
foreach ($iterator as $key=>$value) { 
    $zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key"); 
} 

// close and save archive 
$zip->close(); 
echo "Archive created successfully."; 
?>

PHP自带ZipArchive扩展，这是为你的权利。

当心阿德南的例子可能出现的问题：如果目标myarchive.zip是源文件夹中，那么你需要排除的循环，或在创建存档文件之前运行迭代器（如果它不存在）。这是一个修改后的脚本，它使用后一个选项，并将一些配置变量添加到顶部。不应该使用这个添加到现有的存档。

<?php 
// Config Vars 

$sourcefolder = "./"   ; // Default: "./" 
$zipfilename = "myarchive.zip"; // Default: "myarchive.zip" 
$timeout  = 5000   ; // Default: 5000 

// instantate an iterator (before creating the zip archive, just 
// in case the zip file is created inside the source folder) 
// and traverse the directory to get the file list. 
$dirlist = new RecursiveDirectoryIterator($sourcefolder); 
$filelist = new RecursiveIteratorIterator($dirlist); 

// set script timeout value 
ini_set('max_execution_time', $timeout); 

// instantate object 
$zip = new ZipArchive(); 

// create and open the archive 
if ($zip->open("$zipfilename", ZipArchive::CREATE) !== TRUE) { 
    die ("Could not open archive"); 
} 

// add each file in the file list to the archive 
foreach ($filelist as $key=>$value) { 
    $zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key"); 
} 

// close the archive 
$zip->close(); 
echo "Archive ". $zipfilename . " created successfully."; 

// And provide download link ?> 
<a href="http:<?php echo $zipfilename;?>" target="_blank"> 
Download <?php echo $zipfilename?></a>
