Added in Head.htm, that is, add "$stime =microtime (True) in the default template; Gets the time that the program started executing " Copy CodeThe code is as follows: $stime=microtime(true);

Gettickcount () and getcurrenttime () are both accurate to 55 ms (one tick is 55 ms ). To be accurate to milliseconds, use the timegettime function or the queryperformancecounter function. For specific examples, refer to qa001022 "using

Class runtime { var $StartTime = 0; var $StopTime = 0; function Get_microtime () { List ($usec, $sec) = Explode (, microtime ()); return (float) $usec (float) $sec); } function Start () { $this->starttime = $this->get_microtime (); } function

Many elaborate programs need to calculate the time consumed by one execution.Or, we often test the time it takes to read data. The code is as follows:Copy code System. currentTimeMillis () can read the current time in milliseconds. The value is
