use file to put each line of the file into an array element.  Use a foreach loop on that array.  In the foreach loop, explode at the space.  You might possibly have to use preg_split instead, using \s.  Your number will be the 2nd element of the explode/preg_split.

thanks alot, but the issue that it actually not in FILE it is in $text, is there something like FILE function to extract it ?

 

thanks

maybe you can first explode $text at \n to get your initial array that file() would have given you.

Warning: file() expects parameter 1 to be string, array given in /var/www/test1.php on line 11

 

<?php
   include('SSH2.php');

   $ssh = new Net_SSH2('192.168.58.133');
   if (!$ssh->login('test', 'test')) {
       exit('Login Failed');
   }

   $pizza = ($ssh->exec('ps -ux'));
   $pieces = explode(" ", $pizza);
   $lines = file($pieces);

?>

if your data is already in a string you don't need file at all.  If $pizza is what you are saying has that data, then try

 

$lines = explode("\n", $pizza);

 

to get each line into an array.  Then for each line, explode at the space.
