I want to get server CPU and RAM usage using php. The script should work on windows and linux.
How would I do that?

To get the current memory usage, we can use the memory_get_usage() function, and to get the highest amount of memory used at any point, we can use the memory_get_peak_usage() function.
Using the Task Manager Press the Windows key , type task manager, and press Enter . In the window that appears, click the Performance tab. On the Performance tab, a list of hardware devices is displayed on the left side.
The memory_get_usage function can be used to track the memory usage. The 'malloc' function is not used for every block required, instead a big chunk of system memory is allocated and the environment variable is changed and managed internally. The above mentioned memory usage can be tracked using memory_get_usage().
The first function will return the Server Memory Usage:
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;
}
This function will return the Server CPU Usage:
function get_server_cpu_usage(){
$load = sys_getloadavg();
return $load[0];
}
