PHP执行Rundll [英] PHP execution for rundll

问题描述

有人对我如何在php中执行以下代码有想法吗?

Does anyone have an idea on how I can execute the below code in php ?

 <?php
  $output = "rundll32 printui.dll PrintUIEntry /in /n \\omgb-omga-1\printer-hr";
 ?>

运行上面的命令不会添加网络打印机...

Running the above doesn't add the network printer...

我在php中的语法正确吗?因为我可以在将命令粘贴到命令提示符时添加打印机.

Does my syntax in php is correct ? Because I am able to add the printer when i paste the command in command prompt .

推荐答案

使用 exec()(请注意，可能需要将完整路径添加到rundll32.exe):

Use exec() (note that it may need to add the full path to rundll32.exe) :

$output = array();
exec("C:\\Windows\\system32\\rundll32.exe PrintUIEntry /in /n \\\\omgb-omga-1\\printer-hr", $output);
var_dump($output);

根据此答案，应该转义反斜杠(在我的示例中是这样)，但我不是确定命令的参数是否需要.

According to this answer, backslashes should be escaped (which I did in my example), but I'm not sure if it's needed for the command's arguments.

请注意，exec()仅返回命令返回的最后一行；要获得整个输出，您需要使用一个单独的数组(此处为$output)，该数组将填充命令的输出.

Note that exec() only returns the last line returned by the command; to get the entire output you need to use a separate array (here $output) that will be filled with the command's output.
