PHP Powershell命令 [英] PHP Powershell command

问题描述

尝试在php中运行以下命令以运行powershell命令...

Trying to run the following command in php to run powershell command...

以下作品:

$output = shell_exec(escapeshellcmd('powershell get-service | group-object'));

我不能像这样运行它:

$output = shell_exec('powershell get-service | group-object');

它不会通过管道|字符

但是如果我尝试运行:

$output = shell_exec(escapeshellcmd('powershell get-service | where-object {$_.status -eq "Running"}'));

我没有输出.

以下内容:

$cmd = escapeshellcmd('powershell get-service | where-object {$_.status -eq "Running"}');

返回:

powershell get-service ^| where-object ^{^$_.status -eq ^"Running^"^}

关于为什么发生这种情况以及如何解决此问题的任何建议?

Any suggestions on why this is happening and how to fix this?

我也可以将其作为.ps1脚本运行，但我希望能够将$ var传递给它.

Also I could run it as .ps1 script but I want to be able to pass $var to it.

推荐答案

尽管我没有任何PHP经验，但我还是会tab一口.

I'll take a stab although I have no PHP experience whatsoever.

我感觉正在发生的事情是您的管道字符是由命令外壳而不是PowerShell解释的.例如，如果您在cmd.exe命令提示符下运行以下命令:

I have a feeling that what's happening is your pipe character is being interpreted by the command shell instead of PowerShell. For example if you ran the following at the cmd.exe command prompt:

dir /s | more

第一个命令的输出将通过管道传递到第二个命令的输入，就像您在PowerShell中所期望的那样.

The output of the first command gets piped to the input of the second just like you'd expect in PowerShell.

转义字符串只会使问题变得更糟，因为您以某种方式转换字符串，因此PowerShell不知道如何对其进行转义.

Escaping the string will only make the problem worse because you're transforming the string in such a way that PowerShell has no idea how to unescape it.

尝试将原始PowerShell表达式括在如下报价中:

Try enclosing your original PowerShell expression in a quote like the following:

$output = shell_exec('powershell.exe -c "get-service | group-object"');

或者最好是看起来像有一个 exec ()函数不会通过命令外壳.这可能会更好.

Or preferably, it looks like there's an exec() function that does not go through the command shell. This might work better.

$output = exec('powershell.exe -c get-service | group-object');
