以下是一個使用PHP遞歸函數對目錄進行壓縮打包的示例代碼：

<?php

function zipDirectory($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);

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

            $file = realpath($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();
}

// 用法示例
$source = '/path/to/sourceDirectory';
$destination = '/path/to/destinationArchive.zip';

if (zipDirectory($source, $destination)) {
    echo 'Directory successfully compressed and packed into ' . $destination;
} else {
    echo 'Failed to compress directory';
}

請確保在執行此代碼之前已經安裝了PHP的Zip擴展。您可以將$source替換為您要打包的目錄的路徑，將$destination替換為打包文件的保存路徑。執行代碼后，將會將目錄壓縮打包成一個zip文件。
