Execute Powershell script within PHP in IIS

<?php

error_reporting(E_ALL);

$psPath = "powershell.exe";
$psDir = "C:\\wamp\\www\\ps\\";
$psScript = "SampleHTML.ps1";
$runScript = $psDir. $psScript;

//var_dump($runCMD);
$output = exec($runCMD);
echo $output;

Hello,

 

I am working on a small project to get results from powershell script by using PHP. For some reason in PHP logs I get Exec unable to fork. Above is the script I wrote to execute powershell script within php. My webserver is IIS 7, and app pool is using a domain user that has full rights for Powershell to execute and get remote server results.

exec() uses a shell so you also need rights on cmd.exe. Alternatively you can use the proc_* functions; they're harder to use but are much more powerful, and can* execute programs directly without using a shell.

 

* with $other_options's bypass_shell=true

Thanks Requinix. I will try out proc_open function and see how it goes.

<?php

//error_reporting(E_ALL);

$psPath = "powershell.exe";
$psDir = "C:\\wamp\\www\\ps\\";
$psScript = "SampleHTML.ps1";
$runScript = $psDir. $psScript;
$prem = "-Action enable";
$runCMD = $psPath. " " .$runScript. " " .$prem;

var_dump($runCMD);
$output = proc_open($runCMD);

$exitcode = proc_close($output);

echo $exitcode;

?>

string(59) "powershell.exe C:\wamp\www\ps\SampleHTML.ps1 -Action enable" 
Warning: proc_open() expects at least 3 parameters, 1 given in C:\wamp\www\powershell.php on line 13

Hi,

 

I tried the proc_open function. I think I am missing some parameters to make it functional. Here is the error I am receiving:

 

Here is the modified code:

[requinix]

proc_open

proc_close

 

You can't just swap the function names around. Read the documentation on how to use them.

 

[edit] Additionally, IIRC, you have to do a little more with PowerShell for everything to run smoothly. Such as send an "exit" command to get the process to quit by itself.
