使用PHP exec（）显示执行的命令和输出

Question

I am debugging a script that is supposed to delete a file and would love to know if there is a way to echo back the command I am running along with the results:

echo exec("rm ./" . strtolower(end(split('\/',$originalName))));

This will return the result, but with the incoming data (which should be something like:/plugins/Dropzone/files/xcqzr.png) it would be great to know what exactly is getting passed into it. I know I could do it in a separate process, but wondering if there was a built in way.

Answer 1

You compose the command string beforehand and then pass it to exec().

$command = "rm ./" . strtolower(end(split('\/',$originalName)));
echo 'Command: '.$command.PHP_EOL;
$result = exec($command);
echo 'Result: '.$result.PHP_EOL;
