创建.zip文件

Question

我试图将文件从一个文件夹保存到另一个文件夹.zip文件夹放在不同的目录中.我写了以下代码:

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();
?>

但遗憾的是我无法创建.zip文件夹.我错过了什么步骤？

Answer 1

$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TEST是您的项目文件夹名称.

您可以根据需要定义路径.

Answer 2

是的,我已经解决了我的问题.

在这里,我刚刚更换了代码

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

与代码

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

并完成我的工作.:)

Answer 3

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';
    }
    ?>

创建一个新的 zip 文件

$zip = new ZipArchive;
if ($zip->open('test_new.zip', ZipArchive::CREATE) === TRUE)
{
    // Add files to the zip file
    $zip->addFile('test.txt');
    $zip->addFile('test.pdf');
 
    // Add random.txt file to zip and rename it to newfile.txt
    $zip->addFile('random.txt', 'newfile.txt');
 
    // Add a file new.txt file to zip using the text specified
    $zip->addFromString('new.txt', 'text to be added to the new.txt file');
 
    // All files are added, so close the zip file.
    $zip->close();
}

覆盖现有的 zip 文件

$zip = new ZipArchive;
if ($zip->open('test_overwrite.zip', ZipArchive::OVERWRITE) === TRUE)
{
    // Add file to the zip file
    $zip->addFile('test.txt');
    $zip->addFile('test.pdf');
 
    // All files are added, so close the zip file.
    $zip->close();
}

创建一个新的 zip 文件并将文件添加到文件夹中

$zip = new ZipArchive;
if ($zip->open('test_folder.zip', ZipArchive::CREATE) === TRUE)
{
    // Add files to the zip file inside demo_folder
    $zip->addFile('text.txt', 'demo_folder/test.txt');
    $zip->addFile('test.pdf', 'demo_folder/test.pdf');
 
    // Add random.txt file to zip and rename it to newfile.txt and store in demo_folder
    $zip->addFile('random.txt', 'demo_folder/newfile.txt');
 
    // Add a file demo_folder/new.txt file to zip using the text specified
    $zip->addFromString('demo_folder/new.txt', 'text to be added to the new.txt file');
 
    // All files are added, so close the zip file.
    $zip->close();
}

创建一个新的 zip 文件并将文件移动到不同的文件夹中

$zip = new ZipArchive;
if ($zip->open('test_folder_change.zip', ZipArchive::CREATE) === TRUE)
{
    // Add files to the zip file
    $zip->addFile('text.txt', 'demo_folder/test.txt');
    $zip->addFile('test.pdf', 'demo_folder1/test.pdf');
 
    // All files are added, so close the zip file.
    $zip->close();
}

使用目录中的所有文件创建一个 zip 文件

$zip = new ZipArchive;
if ($zip->open('test_dir.zip', ZipArchive::OVERWRITE) === TRUE)
{
    if ($handle = opendir('demo_folder'))
    {
        // Add all files inside the directory
        while (false !== ($entry = readdir($handle)))
        {
            if ($entry != "." && $entry != ".." && !is_dir('demo_folder/' . $entry))
            {
                $zip->addFile('demo_folder/' . $entry);
            }
        }
        closedir($handle);
    }
 
    $zip->close();
}

将多个文件和目录添加到一个 zip 文件

$zip = new ZipArchive;
if ($zip->open('test_files_dirs.zip', ZipArchive::OVERWRITE) === TRUE)
{
    // Add directory1
    if ($handle = opendir('demo_folder/directory1/'))
    {
        while (false !== ($entry = readdir($handle)))
        {
            if ($entry != "." && $entry != "..")
            {
                $zip->addFile('demo_folder/directory1/' . $entry);
            }
        }
        closedir($handle);
    }
 
    // Add directory2
    if ($handle = opendir('demo_folder/directory2/'))
    {
        while (false !== ($entry = readdir($handle)))
        {
            if ($entry != "." && $entry != "..")
            {
                $zip->addFile('demo_folder/directory2/' . $entry);
            }
        }
        closedir($handle);
    }
 
    // Add directory3
    if ($handle = opendir('demo_folder/directory3/'))
    {
        while (false !== ($entry = readdir($handle)))
        {
            if ($entry != "." && $entry != "..")
            {
                $zip->addFile('demo_folder/directory3/' . $entry);
            }
        }
        closedir($handle);
    }
 
    // Add more files
    $zip->addFile('demo_folder/index.txt');
 
    $zip->close();
}
