创建的.zip文件

问题描述：

我试图从一个文件夹中保存文件到另一个。 zip文件夹放置在不同的目录中。我写了下面的代码：创建的.zip文件

archive.php

<?php 
    $zip = new ZipArchive(); 
    $zip->open('example.zip', ZipArchive::CREATE); 
    $srcDir = "/home/sam/uploads/"; 
    $files= scandir($srcDir); 
    //var_dump($files); 
    unset($files[0],$files[1]); 
    foreach ($files as $file) { 
     $zip->addFile("{$file}");  
    } 
    $zip->close(); 
?>

但遗憾的是我不能创建的.zip文件夹。我错过了什么？

答

$zip = new ZipArchive(); 

$DelFilePath="first.zip"; 

if(file_exists($_SERVER['DOCUMENT_ROOT']."/TEST/".$DelFilePath)) { 

     unlink ($_SERVER['DOCUMENT_ROOT']."/TEST/".$DelFilePath); 

} 
if ($zip->open($_SERVER['DOCUMENT_ROOT']."/TEST/".$DelFilePath, ZIPARCHIVE::CREATE) != TRUE) { 
     die ("Could not open archive"); 
} 
    $zip->addFile("file_path","file_name"); 

// close and save archive 

$zip->close();

这里测试项目文件夹的名称。

您可以根据需要定义路径。

请参见本文下面的例子：

<?php 
    $error = "";  //error holder 
    if(isset($_POST['createpdf'])){ 
     $post = $_POST;  
     $file_folder = "files/"; // folder to load files 
     if(extension_loaded('zip')){ // Checking ZIP extension is available 
      if(isset($post['files']) and count($post['files']) > 0){ // Checking files are selected 
       $zip = new ZipArchive();   // Load zip library 
       $zip_name = time().".zip";   // Zip name 
       if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE){  // Opening zip file to load files 
        $error .= "* Sorry ZIP creation failed at this time<br/>"; 
       } 
       foreach($post['files'] as $file){    
        $zip->addFile($file_folder.$file);   // Adding files into zip 
       } 
       $zip->close(); 
       if(file_exists($zip_name)){ 
        // push to download the zip 
        header('Content-type: application/zip'); 
        header('Content-Disposition: attachment; filename="'.$zip_name.'"'); 
        readfile($zip_name); 
        // remove zip file is exists in temp path 
        unlink($zip_name); 
       } 

      }else 
       $error .= "* Please select file to zip <br/>"; 
     }else 
      $error .= "* You dont have ZIP extension<br/>"; 
    }

是的，我已经解决了我的问题。

在这里，我刚更换过代码

$zip->addFile("{$file}");

与代码

$zip->addFromString(basename($file), file_get_contents($file));

，并让我的工作完成。 :)

这不适用于大文件... – 2018-03-08 09:53:14

试试这个代码：

<?php 
    $zip = new ZipArchive; 
    if ($zip->open(getcwd() . '/test.zip', ZipArchive::CREATE) === TRUE) { 
     $zip->addFile(getcwd() . '/file.txt', 'newname.txt'); 
     $zip->close(); 
     echo 'ok'; 
    } else { 
     echo 'failed'; 
    } 
    ?>
