Voici un petit code à améliorer qui permet de faire des shutdown, taskkill et autre...

<?php

//phpinfo();

// NOM DES ORDINATEUR SUR LE RESEAU
$dev16 = array("\\\\PC1,\\\\PC2,\\\\PC3"); // .. ect
                  
if(isset($_POST['on']))
{
   for($i=0;$i<=15;$i++)
   { 
     $cmd = "shutdown /r /m $dev16[$i] /t 60 && exit"; 
     echo $cmd.'<br />';
     //$cmd = "taskkill /s $dev16[$i] /f /im firefox.exe && exit"; 
     //$cmd3 = "start \\\Tests-a04014cb7\\testtre\\index.html"; 
     //$cmd2 = "start http://www.google.fr";
     //sleep(1);
     exec($cmd, $exec_output, $exec_retval);
     echo 'L\'ordinateur redemarre!!! <br />';
   } 
} 
  
if(isset($_POST['onf']))
{
   for($i=0;$i<=15;$i++)
   { 
    //$cmd = "shutdown /r /m $dev16[$i] /t 60 && exit"; 
    $cmd = "taskkill /s $dev16[$i] /f /im firefox.exe && exit"; 
    //$cmd3 = "start \\\Tests-a04014cb7\\testtre\\index.html"; 
    //$cmd2 = "start http://www.google.fr";
    //sleep(1);
    exec($cmd, $exec_output, $exec_retval);  
   }
   echo 'firefox.exe redemarre!!! <br />'; 
} 

if(isset($_POST['ons']))
{
   for($i=0;$i<=18;$i++)
   { 
    //$cmd = "shutdown /r /m $dev16[$i] /t 60 && exit"; 
    $cmd = "taskkill /s $dev16[$i] /f /im service.exe && exit"; 
    //$cmd3 = "start \\\Tests-a04014cb7\\testtre\\index.html"; 
    //$cmd2 = "start http://www.google.fr";
    //sleep(1);
    exec($cmd, $exec_output, $exec_retval);  
   }
   echo 'service.exe redemarre!!! <br />'; 
}

if(isset($_POST['ona']))

   for($i=0;$i<=15;$i++)
   { 
    //$cmd = "shutdown /r /m $dev16[$i] /t 60 && exit";

$dev16 devrait pouvoir être rempli dynamiquement!

Je pense qu'il y a moyen de récuperer les noms des machines du réseau dans lequel on se trouve...
