how do I get the pid of a specific process

I am writing a PHP script that connects to a remove server using SSH. what I need to do is to check if a specific process is running or not so that I can terminate it. I am using the phpseclib. following code connects to the server and lists the processes but i am really stuck in getting the process id of each processes!

include('Net/SSH2.php');
$ssh = new Net_SSH2('192.168.1.1');
$ssh->login('username', 'password') or die("SSH Login failed");
$ps = $ssh->exec('ps -ef | grep ".php"');
echo $ps;

The output is :

root     32405     1  3 09:45 ?        00:03:30 php /afghanwiz/distributor1.php
root     32407     1  3 09:45 ?        00:03:33 php /afghanwiz/distributor2.php

I have tried to get the pid (here is 32405 and 32407) using exploding the lines and words but no success. Anyone has any idea of such an issue?

Solution

  • If you know that they are running as root, this might work for you:

    $output = <<<EOF
root     32405     1  3 09:45 ?        00:03:30 php /afghanwiz/distributor1.php
root     32407     1  3 09:45 ?        00:03:33 php /afghanwiz/distributor2.php
EOF;

preg_match_all('/root\s+(\d+)/', $output, $m);
var_dump($m[1]);

    If the username can be anything, something like:

    preg_match_all('/[a-z_][a-z0-9_]{0,30}\s+(\d+)/', $output, $m);

    will work. Btw, the username regex was taken from here: https://stackoverflow.com/a/6949914/171318 Thanks!
