PHP doesn't have the ZipArchive extension – what should I do?

If your PHP environment does not have the ZipArchive extension installed, you may consider using a third-party PHP compression/decompression library, such as PclZip.

PclZip is a pure PHP-based ZIP compression and decompression library that is easy to use. You simply need to download PclZip and then include its library file in your code:

require_once('path/to/pclzip.lib.php');

composer require pclzip/pclzip

Function Example

function downloadAndExtract($installDir, $remoteZipUrl) {
    // 下载远程 Zip 文件并保存到本地
    $tempZip = tempnam(sys_get_temp_dir(), 'download_');
    $fp = fopen($tempZip, 'w');
    $ch = curl_init($remoteZipUrl);
    curl_setopt($ch, CURLOPT_FILE, $fp);
    $success = curl_exec($ch);
    curl_close($ch);
    fclose($fp);
    if (!$success) {
        throw new Exception('Failed to download the remote ZIP file.');
    }

    // 解压缩文件到指定目录
    $zip = new PclZip($tempZip);
    if ($zip->extract(PCLZIP_OPT_PATH, $installDir) === 0) {
        throw new Exception('Failed to extract the ZIP file.');
    }

    // 删除临时文件和 install 目录下的所有文件
    unlink($tempZip);
    $files = glob($installDir . '/*');
    foreach ($files as $file) {
        if (is_file($file)) {
            unlink($file);
        }
    }
}
