httpcreditcard.bankcomm.com PHP A page execution time class code

Core code

<?php Class timer//page Execution time class {var starttime;//page start execution time var stoptime;//page end Execution time var spendtime;//page execution takes time function getmic Rotime ()//Gets the floating-point number {list (usec,sec) =explode ("", Microtime ()) that returns the current microseconds; Return ((float) usec + (float) sec); } function Start ()//page starts execution function, returns the start Page execution time {this->starttime=this->getmicrotime ();} function display ()// Displays the time the page was executed {this->stoptime=this->getmicrotime (); this->spendtime=this->stoptime-this->starttime; Return round (this->spendtime,10); }}/* Call Method Timer=new timer (); Timer->start (); /* Insert the script or code you want to execute here for (i=0;i<100000;i++) {echo i; echo.
"; } *///echo "

PHP detects each piece of code execution time

<?php//instance 1/** * @start time */function prostarttime () {  global $startTime;  $mtime 1 = Explode ("", Microtime ());  $startTime = $mtime 1[1] + $mtime 1[0];} /** * @End time */function proendtime () {  global $startTime, $set;  $mtime 2 = Explode ("", Microtime ());  $endtime = $mtime 2[1] + $mtime 2[0];  $totaltime = ($endtime-$startTime);  $totaltime = Number_format ($totaltime, 7);  echo "
Process time: ". $totaltime;} The program call begins when Prostarttime (); sleep (1);   The sleep () delay code executes several seconds proendtime (); The execution time that the program consumes in each paragraph sleep (2);p roendtime (); Sleep (3);p roendtime (); /************************************************* Gorgeous split-line **************************************************/// Instance 2$t1 = Microtime (True), sleep (3), $t 2 = Microtime (true), echo ' program time consuming '. Round ($t 2-$t 1,3). ' Seconds ';? >
