PHP: Remote download of compressed PHP files for temporary use

PHP can be used.file_put_contents()The function downloads the remotely compressed file to a local temporary file, decompresses it using the PHP ZipArchive extension, and then includes the required PHP file.

The following is an example code that downloads a file named from a remote URL:example.zipThe compressed file; then decompress the file namedexample.phpAdd the file:

// 远程压缩文件的URL
$zip_url = "http://example.com/example.zip";

// 创建一个临时文件来保存下载的ZIP文件
$temp_file = tempnam(sys_get_temp_dir(), "zip");

// 使用cURL下载文件并将其保存到临时文件中
$ch = curl_init($zip_url);
$fp = fopen($temp_file, "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);

// 解压缩ZIP文件并包含所需的PHP文件
$zip = new ZipArchive();
if ($zip->open($temp_file) === true) {
    $zip->extractTo(sys_get_temp_dir());
    $zip->close();
    include sys_get_temp_dir() . "/example.php";
} else {
    // 处理无法打开ZIP文件的情况
    echo "无法打开ZIP文件";
}

Note that this example merely illustrates a basic approach; you can adjust it according to your specific requirements. If the file you intend to download is large, you may need to use streaming to avoid loading the entire file into memory. Additionally, when performing any operation involving external code, you should carefully consider security implications.
