zipArchive如何保存文件夹中的文件夹

Question

我正在写一个脚本，需要存档文件夹和文件里面，但我不知道如何做到这一点，如果有一个文件夹内的另一个文件夹。我将通过实例讲解，让规范工作

Warning: ZipArchive::close(): Read error: Is a directory in /путь до скрипта/public_html/crm/drive/drive.php on line 102

Folder + 
 
     File1 
 
     File2 
 
     And so on (so it works) 
 

 
But does not want to work like that 
 

 
Folder + 
 
       File1 
 
       FOLDER (this does not work)

的问题是如何让这个如果脚本中所看到的文件夹，还下载了如果我看到该文件夹​​内的文件夹也分别下载文件夹中的文件？这里是我的脚本

if (isset($_POST['createPath'])) {//Check that the button is clicked 
 
     
 
$zip = new ZipArchive(); // Create an archive 
 
$zip_name = time().".zip"; // file name 
 
if ($zip->open($zip_name, ZipArchive::CREATE) !== true) { // open file 
 
    die ("Could not open archive");//If the file does not open 
 
} 
 
$var = $_POST["pathUpload"];// Array of variables that are passed through the form 
 
foreach ($var as $key_var) {// We process the array in a loop 
 
$iterator = new RecursiveDirectoryIterator($key_var);//There is a recursive search of the file system directories 
 
foreach ($iterator as $key => $value) {// We process an array of files 
 
    $path = pathinfo($value);//Check the path or revert the path to the file 
 
    if ($path['basename'] == '.' || $path['basename'] == '..') continue;//Check those files that you download if there are points in the files then download 
 

 
    $zip->addFile(realpath($key), $key);//Add the file to the server 
 

 

 
    
 
} 
 

 
$zip->close();//Close archive 
 
    if (file_exists($zip_name)) { 
 
     // Give the file to download 
 
     header('Content-type: application/zip', 'charset=utf-8'); 
 
     header('Content-Disposition: attachment; filename="'.$zip_name.'"'); 
 
     ob_end_flush();//Buffering since without it nothing will work 
 
     readfile($zip_name); //Read the file 
 

 
     unlink($zip_name);//Delete the variable 
 
    } 
 
} 
 

 
}

Answer 1

，因为你正试图添加目录与方法邮编

// this function only for adding files! 
public function addFile ($filename, $localname = null, $start = 0, $length = 0) {} 

方法允许你添加目录

public function addEmptyDir ($dirname) {} 

错误

您遇到的另一个问题是您以错误的方式使用目录迭代器。

// this way only loop on directories in 
$iterator = new RecursiveDirectoryIterator($key_var);//There is a recursive search of the file system directories 

正确的方法是使用在RecursiveDirectoryIteratorRecursiveIteratorIterator - 一起来看看在文档的选项。

例如：

// the right way to recursive get list of the file system directories and files 
$iterator = new RecursiveIteratorIterator(
      new RecursiveDirectoryIterator($key_var, RecursiveDirectoryIterator::SKIP_DOTS), // skip . and .. 
      RecursiveIteratorIterator::SELF_FIRST, 
      RecursiveIteratorIterator::CATCH_GET_CHILD // Ignore "Permission denied" 
);

所以要得到它的工作，你的代码应该是这样的：

<?php 

if (isset($_POST['createPath'])) {//Check that the button is clicked 

    $zip  = new ZipArchive(); // Create an archive 
    $zip_name = time() . ".zip"; // file name 
    if ($zip->open($zip_name, ZipArchive::CREATE) !== true) { // open file 
     die ("Could not open archive");//If the file does not open 
    } 

    $var = $_POST["pathUpload"];// Array of variables that are passed through the form 
    foreach ($var as $key_var) {// We process the array in a loop 

     // There is a recursive search of the file system directories 
     $iterator = new RecursiveIteratorIterator(
      new RecursiveDirectoryIterator($key_var, RecursiveDirectoryIterator::SKIP_DOTS), // skip . and .. 
      RecursiveIteratorIterator::SELF_FIRST, 
      RecursiveIteratorIterator::CATCH_GET_CHILD // Ignore "Permission denied" 
     ); 

     // all directories and subdir 
     foreach ($iterator as $path => $dir) { 
      if (!$dir->isDir()) && is_file($path) { 
       $zip->addFile(realpath($path)); //Add the file to the server 
      } 
      if ($dir->isDir()) { 
       // do nothing 
      } 
     } 

     $zip->close(); //Close archive 
     if (file_exists($zip_name)) { 
      // Give the file to download 
      header('Content-type: application/zip', 'charset=utf-8'); 
      header('Content-Disposition: attachment; filename="' . $zip_name . '"'); 
      ob_end_flush();//Buffering since without it nothing will work 
      readfile($zip_name); //Read the file 

      unlink($zip_name);//Delete the variable 
     } 
    } 

} 

编码快乐:)
