A PHP class that calculates the program run time

/** * Calculate program Run time * filename:js_runtime.php */ Class Timer { Private $StartTime = 0;//program run start time Private $StopTime = 0;//program Run end time Private $TimeSpent = 0;//program takes time to run function Start () {//program run start $this->starttime = Microtime (); } function Stop () {//program run end $this->stoptime = Microtime (); } function spent () {//time spent by program run if ($this->timespent) { return $this->timespent; } else { List ($StartMicro, $StartSecond) = Explode ("", $this->starttime); List ($StopMicro, $StopSecond) = Explode ("", $this->stoptime); $start = Doubleval ($StartMicro) + $StartSecond; $stop = Doubleval ($StopMicro) + $StopSecond; $this->timespent = $stop-$start; Return substr ($this->timespent,0,8). " Seconds ";//returns the program run time difference that gets to } } } $timer = new timer (); $timer->start (); //... Code to run the program $timer->stop (); echo "Program run Time:". $timer->spent (); ?> Copy Code
