如何使用 PHP 压缩整个文件夹 [英] How to zip a whole folder using PHP

问题描述

我在 stackoveflow 上找到了一些关于如何压缩特定文件的代码，但是特定文件夹呢?

文件夹/索引.html图片.jpg重要.txt

在我的文件夹里面，有文件.压缩My Folder 后，我还想删除文件夹中除important.txt 之外的全部内容.

在 stack 中找到了这个>

我需要你的帮助.谢谢.

解决方案

代码更新 2015/04/22.

压缩整个文件夹:

//获取我们文件夹的真实路径$rootPath = realpath('folder-to-zip');//初始化归档对象$zip = 新的 ZipArchive();$zip->open('file.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);//创建递归目录迭代器/** @var SplFileInfo[] $files */$files = new RecursiveIteratorIterator(新的递归目录迭代器($rootPath)，RecursiveIteratorIterator::LEAVES_ONLY);foreach ($files as $name => $file){//跳过目录(它们会被自动添加)if (!$file->isDir()){//获取当前文件的真实路径和相对路径$filePath = $file->getRealPath();$relativePath = substr($filePath, strlen($rootPath) + 1);//将当前文件添加到存档$zip->addFile($filePath, $relativePath);}}//只有在关闭对象后才会创建 Zip 存档$zip->close();

压缩整个文件夹+删除除important.txt"之外的所有文件:

//获取我们文件夹的真实路径$rootPath = realpath('folder-to-zip');//初始化归档对象$zip = 新的 ZipArchive();$zip->open('file.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);//初始化空的删除列表"$filesToDelete = array();//创建递归目录迭代器/** @var SplFileInfo[] $files */$files = new RecursiveIteratorIterator(新的递归目录迭代器($rootPath)，RecursiveIteratorIterator::LEAVES_ONLY);foreach ($files as $name => $file){//跳过目录(它们会被自动添加)if (!$file->isDir()){//获取当前文件的真实路径和相对路径$filePath = $file->getRealPath();$relativePath = substr($filePath, strlen($rootPath) + 1);//将当前文件添加到存档$zip->addFile($filePath, $relativePath);//将当前文件添加到删除列表"//稍后删除它会导致 ZipArchive 仅在调用 close 函数后创建存档，并且 ZipArchive 锁定文件直到创建存档)if ($file->getFilename() != 'important.txt'){$filesToDelete[] = $filePath;}}}//只有在关闭对象后才会创建 Zip 存档$zip->close();//从删除列表"中删除所有文件foreach ($filesToDelete as $file){取消链接($文件)；}

I have found here at stackoveflow some codes on how to ZIP a specific file, but how about a specific folder?

Folder/
  index.html
  picture.jpg
  important.txt

inside in My Folder, there are files. after zipping the My Folder, i also want to delete the whole content of the folder except important.txt.

Found this here at stack

I need your help. thanks.

Code updated 2015/04/22.

Zip a whole folder:

// Get real path for our folder
$rootPath = realpath('folder-to-zip');

// Initialize archive object
$zip = new ZipArchive();
$zip->open('file.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);

// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($rootPath),
    RecursiveIteratorIterator::LEAVES_ONLY
);

foreach ($files as $name => $file)
{
    // Skip directories (they would be added automatically)
    if (!$file->isDir())
    {
        // Get real and relative path for current file
        $filePath = $file->getRealPath();
        $relativePath = substr($filePath, strlen($rootPath) + 1);

        // Add current file to archive
        $zip->addFile($filePath, $relativePath);
    }
}

// Zip archive will be created only after closing object
$zip->close();

Zip a whole folder + delete all files except "important.txt":

// Get real path for our folder
$rootPath = realpath('folder-to-zip');

// Initialize archive object
$zip = new ZipArchive();
$zip->open('file.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);

// Initialize empty "delete list"
$filesToDelete = array();

// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($rootPath),
    RecursiveIteratorIterator::LEAVES_ONLY
);

foreach ($files as $name => $file)
{
    // Skip directories (they would be added automatically)
    if (!$file->isDir())
    {
        // Get real and relative path for current file
        $filePath = $file->getRealPath();
        $relativePath = substr($filePath, strlen($rootPath) + 1);

        // Add current file to archive
        $zip->addFile($filePath, $relativePath);

        // Add current file to "delete list"
        // delete it later cause ZipArchive create archive only after calling close function and ZipArchive lock files until archive created)
        if ($file->getFilename() != 'important.txt')
        {
            $filesToDelete[] = $filePath;
        }
    }
}

// Zip archive will be created only after closing object
$zip->close();

// Delete all files from "delete list"
foreach ($filesToDelete as $file)
{
    unlink($file);
}
