'How do I force PHP to load without waiting for ssh2

Currently I have a script that uses SSH2 to execute a c program on a server, however the webpage takes the x seconds to load that the script waits. Is there a way to make php send the command through ssh and not wait for the response? Thanks My current code:

<?php
$ssh = ssh2_connect('********', 22);
ssh2_auth_password($ssh, 'root', '**********');
$stream = ssh2_exec($ssh, './sr1 80 4 400 400 20');
fclose($stream);
?>

(Censored server IP and Password for obvious reasons)

Using http://phpseclib.sourceforge.net/ ...

<?php
include('Net/SSH2.php');

$ssh = new Net_SSH2('********', 22);
$ssh->login('root', '**********');
$ssh->enablePTY();
$ssh->exec('nohup ./sr1 80 4 400 400 20 &');

You can try it with and without the nohup and & but my guess is that they're necessary.

You can run your code in a Thread in order to run it asynchronously:

<?php
class MySsh extends Thread {
    public function run() {
        $ssh = ssh2_connect('********', 22);
        ssh2_auth_password($ssh, 'root', '**********');
        $stream = ssh2_exec($ssh, './sr1 80 4 400 400 20');
        fclose($stream);
    }
}
$mySsh = new MySsh();
var_dump($mySsh->start());
?>

Note that to use Threads in php, you need to have the pthreads library installed.

ssh2_connect, ssh2_auth_password is required for ssh login.

ssh2_exec execute the command given second argument './sr1'. Can you please provide what exactly it does with snippets ?

Secondly, ssh2_exec : Execute a command on a remote server. and I think it will wait for your command to complete the execution and then return.

Can you try using ssh2_shell : Request an interactive shell

You can probably, open shell and invoke your command to run background or in different process and exit from shell. I think it can be more faster then ssh2_exec.

it works for me:

$connection = ssh2_connect('host', 22);
ssh2_exec($connection, "screen -dmS 'sr-script' ./sr1 80 4 400 400 20 2>&1");
