SSH session via PHP script

I have a server which can be accessed only using sshv1 when I run the command from my portal towards this server":
       sshpass -p password ssh -1 usernamel@server xxxxx command            
      
  I am getting output which requires to press enter to get more something like this:
 Info: The max number of VTY users is 10, and the number
      of current VTY users on line is 1.
<Server>
       Output
               bla = bla
               bla = bla
  ---- More ----
                    bla = bla

  ---- More ----
                    bla = bla
  ---- More ----
                    bla = bla
  ---- More ----
                     bla = bla      
  ---- More ----
                    bla = bla
 
(Number of Results = 1)
<Server>
Info: The max number of VTY users is 10, and the number
      of current VTY users on line is 0.

 Then the session is terminated.
 I want to create a php script which runs this command, catch the output in an array and parse it in an html table, but I am failing to get the output.

  I have installed lib-ssh2 (But as I can see it will be using SSH2),
  I did the following attempts but with no luck:
Attempt1:
<?php
$raw  = array();
exec('sshpass -p password ssh -1 usernamel@server xxxxx command',$raw);
var_dump($raw);
?>

Here I get the following:
Read from remote host Server IP: Connection reset by peer
array(0) {
}

Attempt2:
<?php
$raw  = array();
$connection = ssh2_connect('Server IP', 22);
ssh2_auth_password($connection, 'username', 'password');
$stream = ssh2_exec($connection, 'command');
stream_set_blocking($stream, true);
$stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);
echo stream_get_contents($stream_out);
?>

Here the script keeps hanging with nothing back

Can someone please guide me what to do?
