How to get Memory and CPU usage in PHP

Perfect simple examples.

-- Memory in procentage % ($mem[2]/1000 for used memory in MB)

function get_server_memory_usage(){

$free = shell_exec('free');
$free = (string)trim($free);
$free_arr = explode("\n", $free);
$mem = explode(" ", $free_arr[1]);
$mem = array_filter($mem);
$mem = array_merge($mem);
$memory_usage = $mem[2]/$mem[1]*100;

return $memory_usage;
}

-- CPU in procentage %

function get_server_cpu_usage(){

$load = sys_getloadavg();
return $load[0];
