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

Folder/
  index.html
  picture.jpg
  important.txt

在中My Folder，有文件。压缩后My Folder，我还想删除文件夹的全部内容，除了important.txt。

在堆栈中找到这个

我需要你的帮助。谢谢。

代码已于2015/04/22更新。

压缩整个文件夹：

// 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();

压缩整个文件夹+删除除“ important.txt”以外的所有文件：

// 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);
}

ZipArchive类中有一个有用的未记录方法：addGlob（）;

$zipFile = "./testZip.zip";
$zipArchive = new ZipArchive();

if ($zipArchive->open($zipFile, (ZipArchive::CREATE | ZipArchive::OVERWRITE)) !== true)
    die("Failed to create archive\n");

$zipArchive->addGlob("./*.txt");
if ($zipArchive->status != ZIPARCHIVE::ER_OK)
    echo "Failed to write files to zip\n";

$zipArchive->close();

现在记录在：www.php.net/manual/en/ziparchive.addglob.php

试试这个：

$zip = new ZipArchive;
$zip->open('myzip.zip', ZipArchive::CREATE);
foreach (glob("target_folder/*") as $file) {
    $zip->addFile($file);
    if ($file != 'target_folder/important.txt') unlink($file);
}
$zip->close();

但是，这不会递归压缩。

我假设它在zip应用程序在搜索路径中的服务器上运行。对于所有基于unix的服务器都应该是真实的，我猜大多数基于Windows的服务器都应该如此。

exec('zip -r archive.zip "My folder"');
unlink('My\ folder/index.html');
unlink('My\ folder/picture.jpg');

之后，存档将驻留在archive.zip中。请记住，文件或文件夹名称中的空格是导致错误的常见原因，应尽可能避免。

我尝试使用下面的代码，它正在工作。该代码是自解释性的，如果您有任何疑问，请告诉我。

<?php
class FlxZipArchive extends ZipArchive 
{
 public function addDir($location, $name) 
 {
       $this->addEmptyDir($name);
       $this->addDirDo($location, $name);
 } 
 private function addDirDo($location, $name) 
 {
    $name .= '/';
    $location .= '/';
    $dir = opendir ($location);
    while ($file = readdir($dir))
    {
        if ($file == '.' || $file == '..') continue;
        $do = (filetype( $location . $file) == 'dir') ? 'addDir' : 'addFile';
        $this->$do($location . $file, $name . $file);
    }
 } 
}
?>

<?php
$the_folder = '/path/to/folder/to/be/zipped';
$zip_file_name = '/path/to/zip/archive.zip';
$za = new FlxZipArchive;
$res = $za->open($zip_file_name, ZipArchive::CREATE);
if($res === TRUE) 
{
    $za->addDir($the_folder, basename($the_folder));
    $za->close();
}
else{
echo 'Could not create a zip archive';
}
?>

这个功能可以将整个文件夹及其内容压缩为一个zip文件，您可以像这样简单地使用它：

addzip ("path/folder/" , "/path2/folder.zip" );

功能：

// compress all files in the source directory to destination directory 
    function create_zip($files = array(), $dest = '', $overwrite = false) {
    if (file_exists($dest) && !$overwrite) {
        return false;
    }
    if (($files)) {
        $zip = new ZipArchive();
        if ($zip->open($dest, $overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {
            return false;
        }
        foreach ($files as $file) {
            $zip->addFile($file, $file);
        }
        $zip->close();
        return file_exists($dest);
    } else {
        return false;
    }
}

function addzip($source, $destination) {
    $files_to_zip = glob($source . '/*');
    create_zip($files_to_zip, $destination);
    echo "done";
}

为什么不尝试EFS PhP-ZiP MultiVolume脚本 ...我压缩并传输了数百个演出和数百万个文件...需要ssh才能有效地创建档案。

但是我相信生成的文件可以直接从php与exec一起使用：

exec('zip -r backup-2013-03-30_0 . -i@backup-2013-03-30_0.txt');

我不知道是否可行。我没有尝试过...

“秘密”在于，归档的执行时间不应超过PHP代码执行所允许的时间。

这是在PHP中制作ZIP的有效示例：

$zip = new ZipArchive();
$zip_name = time().".zip"; // Zip name
$zip->open($zip_name,  ZipArchive::CREATE);
foreach ($files as $file) {
  echo $path = "uploadpdf/".$file;
  if(file_exists($path)){
  $zip->addFromString(basename($path),  file_get_contents($path));---This is main function  
  }
  else{
   echo"file does not exist";
  }
}
$zip->close();

我在google中发现此帖子是第二好的结果，首先是使用exec :(

无论如何，尽管这不能完全满足我的需求。.我决定用我快速但扩展的版本为其他人发布答案。

脚本功能

• 每天备份文件的命名，PREFIX-YYYY-MM-DD-POSTFIX.EXTENSION
• 文件报告/丢失
• 以前的备份清单
• 不压缩/不包含以前的备份；）
• 在Windows / Linux上工作

无论如何，请放到脚本上。。虽然看起来很多。.请记住这里有多余的内容。.因此，请根据需要随时删除报告部分...

而且它看起来也很凌乱，某些东西很容易清理...所以请不要对此发表评论，它只是一个带有基本注释的快速脚本。 ！

在此示例中，它是从根www / public_html文件夹内的目录运行的。因此，只需向上移动一个文件夹即可到达根目录。

它有什么作用？？

它将简单地压缩变量$ pathBase的全部内容并将其存储在同一文件夹中。它对以前的备份进行简单的检测，并跳过它们。

CRON备份

我刚刚在Linux上测试了该脚本，并且使用pathBase的绝对URL在cron作业中运行良好。

使用此功能：

function zip($source, $destination)
{
    if (!extension_loaded('zip') || !file_exists($source)) {
        return false;
    }

    $zip = new ZipArchive();
    if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
        return false;
    }

    $source = str_replace('\\', '/', realpath($source));

    if (is_dir($source) === true) {
        $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

        foreach ($files as $file) {
            $file = str_replace('\\', '/', $file);

            // Ignore "." and ".." folders
            if (in_array(substr($file, strrpos($file, '/')+1), array('.', '..'))) {
                continue;
            }               

            $file = realpath($file);

            if (is_dir($file) === true) {
                $zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
            } elseif (is_file($file) === true) {
                $zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
            }
        }
    } elseif (is_file($source) === true) {
        $zip->addFromString(basename($source), file_get_contents($source));
    }

    return $zip->close();
}

使用示例：

zip('/folder/to/compress/', './compressed.zip');

使用它工作正常。

$dir = '/Folder/';
$zip = new ZipArchive();
$res = $zip->open(trim($dir, "/") . '.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);
if ($res === TRUE) {
    foreach (glob($dir . '*') as $file) {
        $zip->addFile($file, basename($file));
    }
    $zip->close();
} else {
    echo 'Failed to create to zip. Error: ' . $res;
}

在PHP中创建一个zip文件夹。

邮编创建方法

   public function zip_creation($source, $destination){
    $dir = opendir($source);
    $result = ($dir === false ? false : true);

    if ($result !== false) {

        
        $rootPath = realpath($source);
         
        // Initialize archive object
        $zip = new ZipArchive();
        $zipfilename = $destination.".zip";
        $zip->open($zipfilename, 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();
        
        return TRUE;
    } else {
        return FALSE;
    }


}

调用zip方法

$source = $source_directory;
$destination = $destination_directory;
$zipcreation = $this->zip_creation($source, $destination);

我对该脚本做了一些小的改进。

  <?php
    $directory = "./";
    //create zip object
    $zip = new ZipArchive();
    $zip_name = time().".zip";
    $zip->open($zip_name,  ZipArchive::CREATE);
    $files = new RecursiveIteratorIterator(
        new RecursiveDirectoryIterator($directory),
        RecursiveIteratorIterator::LEAVES_ONLY
    );
    foreach ($files as $file) {
        $path = $file->getRealPath();
        //check file permission
        if(fileperms($path)!="16895"){
            $zip->addFromString(basename($path),  file_get_contents($path)) ;
            echo "<span style='color:green;'>{$path} is added to zip file.<br /></span> " ;
        }
        else{
            echo"<span style='color:red;'>{$path} location could not be added to zip<br /></span>";
        }
    }
    $zip->close();
    ?>

这样可以解决您的问题。请尝试一下。

$zip = new ZipArchive;
$zip->open('testPDFZip.zip', ZipArchive::CREATE);
foreach (glob(APPLICATION_PATH."pages/recruitment/uploads/test_pdf_folder/*") as $file) {
    $new_filename = end(explode("/",$file));
    $zip->addFile($file,"emp/".$new_filename);
}           
$zip->close();
