know the period of exec()

[Anon]

Hi,

Could anyone tell me if I can somehow know or retrieve how long have the exec() command been executed?

Thanks in advanced.

Call microtime() before and after the exec() command.

Better yet use this:

function getmicrotime()
{
$mtime = microtime();
$mtime = explode(" ",$mtime);
$mtime = $mtime[1] + $mtime[0];
return ($mtime);
}

$before = getmicrotime();
exec(thecommand);
$after = getmicrotime();
$timetaken = $after - $before; // subtract
echo substr($timetaken,0,4) // trims to X.XX seconds
