osx - Running Multiple PHP SSH2 Script -

i have shop having 10 macs. current able shutdown/restart them remotely through php ssh2 function using code

<?php                 include('net/ssh2.php');                  $server = "hostname";                 $username = "user";                 $password = "pwd";                 $command = "sudo shutdown -r now";                  $ssh = new net_ssh2($server);                 if (!$ssh->login($username, $password)) {                     exit('login failed');                 }                  echo $ssh->exec($command);                 echo "sucessfully restarted blah blah blah";             ?> 

but in order shutdown/restart 10 of terminals, have run 10 different script achieve that. there methods can connect multiple server , run same command?

you store hostnames , credentials in multi-dimensional array. allow iterate through each item using foreach , execute required command on each host. here's example of you'd need do:

<?php include('net/ssh2.php');  $hosts = array(     array(         'hostname' => 'hostname1',         'username' => 'user1',         'password' => 'pwd1'     ),     array(         'hostname' => 'hostname2',         'username' => 'user2',         'password' => 'pwd2'     ) );  $command = "sudo shutdown -r now";  foreach ($hosts $host) {     $ssh = new net_ssh2($host['hostname']);      if (!$ssh->login($host['username'], $host['password'])) {         echo "login failed host '{$host['hostname']}'\n";          continue;     }      echo $ssh->exec($command);     echo "sucessfully restarted {$host['hostname']}\n"; } 

hope helps.

on security: it's recommended use ssh keys rather usernames , passwords. also, make sure keep macs on network not open, example, customers, should use private network.
