使用PHP将目录转换为Zip

Question

如何使用PHP将目录转换为zip文件？

谢谢.

Answer 1

从" 在PHP中压缩目录 ".

这是一个简单的函数,可以递归地压缩任何文件或目录,只需要加载zip扩展.

function Zip($source, $destination)
{
    if (extension_loaded('zip') === true)
    {
        if (file_exists($source) === true)
        {
            $zip = new ZipArchive();

            if ($zip->open($destination, ZIPARCHIVE::CREATE) === true)
            {
                $source = realpath($source);

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

                    foreach ($files as $file)
                    {
                        $file = realpath($file);

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

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

                else if (is_file($source) === true)
                {
                    $zip->addFromString(basename($source), file_get_contents($source));
                }
            }

            return $zip->close();
        }
    }

    return false;
}

像这样称呼它:

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

编辑 - 这个不会保留文件夹结构(检查我的评论):

function Zip($source, $destination)
{
    if (extension_loaded('zip') === true)
    {
        if (file_exists($source) === true)
        {
            $zip = new ZipArchive();

            if ($zip->open($destination, ZIPARCHIVE::CREATE) === true)
            {
                if (is_dir($source) === true)
                {
                    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

                    foreach ($files as $file)
                    {
                        if (is_file($file) === true)
                        {
                            $zip->addFromString(basename($file), file_get_contents($file));
                        }
                    }
                }

                else if (is_file($source) === true)
                {
                    $zip->addFromString(basename($source), file_get_contents($source));
                }
            }

            return $zip->close();
        }
    }

    return false;
}
