我正在使用函数exec（）执行jar文件：

但是我需要检查jar文件是否已损坏或使用php函数。

I am executing jar file through php using function exec();

However i need to check whether jar file corrupted or not using php function.

最满意答案

你可以使用zip检查损坏的jar，因为jar文件是一个压缩文件，所以这会给你一个想法：

$myfile = '/my/jar/file.jar'; $zip = new ZipArchive(); $res = $zip->open($myfile, ZipArchive::CHECKCONS); if ($res !== TRUE) { switch($res) { case ZipArchive::ER_NOZIP: die('not a zip archive'); case ZipArchive::ER_INCONS : die('consistency check failed'); case ZipArchive::ER_CRC : die('checksum failed'); default: die('error ' . $res); } }

要使用zip文件，您需要安装php zip扩展

You can check for corrupted jar using zip because the jar file is a zipped file, so this will give you an idea:

$myfile = '/my/jar/file.jar'; $zip = new ZipArchive(); $res = $zip->open($myfile, ZipArchive::CHECKCONS); if ($res !== TRUE) { switch($res) { case ZipArchive::ER_NOZIP: die('not a zip archive'); case ZipArchive::ER_INCONS : die('consistency check failed'); case ZipArchive::ER_CRC : die('checksum failed'); default: die('error ' . $res); } }

For working with zip files you will need to install the php zip extension
