Write a script to download discuzQ and extract it to the specified git repository to facilitate updating the code.

I encountered a problem. When decompressing the uniapp zip package, there is an extra layer of directory packaging. If you decompress it directly to the specified directory, it will also cause an extra level of directory, as shown below:

Then how to unzip the zip package and remove the extra layer of directoriesuniapp_v2.xxxx, you can see the followingcopy("zip:// {$zipFile}#{$filename}", $newFileName);

 __DIR__ . '/zips', 'uniapp' => __DIR__ . '/uniapp', ]; downloadAndExtract('https://dl.discuz.chat/uniapp_latest.zip', 'uniapp'); function downloadAndExtract($zipUrl, $key) { global $config; echo "正在下载: $zipUrl\n"; $zipData = file_get_contents($zipUrl); $zipFile = $config->zips . "/$key-" . date('Ymd-His') . '.zip'; file_put_contents($zipFile, $zipData); echo "正在解压到 {$config->$key} \n"; $zip = new ZipArchive; if ($key === 'uniapp') { if ($zip->open($zipFile) === true) { $folder = $zip->getNameIndex(0); for ($i = 1; $i < $zip->numFiles; $i++) { $filename = $zip->getNameIndex($i); if (substr($filename, -1, 1) === '/') { continue; } // $folder like => uniapp_v2.1.201029/ // $filename like => uniapp_v2.1.201029/commitlint.config.js $newFileName = $config->$key . '/' . str_replace($folder, '', $filename); if (!file_exists(dirname($newFileName))) { mkdir(dirname($newFileName), 0644, true); } copy("zip://{$zipFile}#{$filename}", $newFileName); } $zip->close(); } } echo "-------------- SUCESS --------------\n"; }
