Answer 1

You can just use the exec function in which you can run sys commands, and it returns the output as a string(in which you can parse).

An example:

<?php
$output = array();

exec("ps" , $output);

var_dump($output);

?>

Output:

array(7) {
  [0]=>
  string(28) "  PID TTY           TIME CMD"
  [1]=>
  string(30) "12986 ttys000    0:00.24 -bash"
  [2]=>
  string(28) "13033 ttys000    0:01.06 irb"
  [3]=>
  string(28) "13054 ttys000    0:01.38 irb"
  [4]=>
  string(40) "14975 ttys000    0:00.06 php -f test.php"
  [5]=>
  string(30) "14010 ttys005    0:00.11 -bash"
  [6]=>
  string(31) "14367 ttys005    0:00.07 python"
}
