I found this one in generator example. 

$start_time=microtime(true);

//do something what you want to measure

$end_time=microtime(true);
echo "time: ", bcsub($end_time, $start_time, 4), "\n";
echo "memory (byte): ", memory_get_peak_usage(true), "\n";

I always use 

microtime()

for timing, and 

memory_get_usage()

for memory usage, together with my IDE (PHPStorm) and XDEBUG this gives quite some useful info.

You can use

microtime()

at the begin of your script, and at the end. The difference will be the execution time. microtime return the timestamp with micro second wich is enough for your needs.
