A class that tests the php program running time

Class runTime { Private $ starTime; // start time Private $ stopTime; // end time Private function getMicTime (){ $ Mictime = microtime (); // Obtain the timestamp and number of microseconds List ($ usec, $ sec) = explode ("", $ mictime); // splits the number of microseconds into an array and converts it to a variable for processing. Return (float) $ usec + (float) $ sec; // forces the converted data to be processed by float points. } Public function star () {// Obtain the start time $ This-> starTime = $ this-> getMicTime (); } Public function stop () {// Obtain the end time $ This-> stopTime = $ this-> getMicTime (); } Public function spent () {// computing program duration Return round ($ this-> stopTime-$ this-> starTime) * 1000; // get the number of milliseconds } } // Example $ Time = new runTime (); $ Time-> star (); For ($ I = 1; $ I <= 1000; $ I ++ ){ Echo (""); } $ Time-> stop (); Echo $ time-> spent (); ?>
