This article introduces a piece of code used to process the benchmark time in PHP. Friends in need can refer to it.
Here is a little example of how to benchmark or time something with php Here is a piece of php code to teach you how to handle the benchmark time. The code is as follows: <?php // a function to get microtime function getmicrotime(){ list($usec, $sec) = explode(" ",microtime()); return ((float)$usec + (float)$sec); } // start time $time_start = getmicrotime(); // a little loop to time for ($i=0; $i < 10000; $i++) { // print the loop number echo $i.'<br />'; } // the end time $time_end = getmicrotime(); // subtract the start time from the end time to get the time taken $time = $time_end - $time_start; // echo a little message echo '<br />Script ran for ' . round($time,2) .' seconds.'; ?> Copy after login This will produce a list of numbers from 0 to 9999 in your browser and tell you how long it took too complete the iterations. The above will produce a list of numbers from 0 to 9999, along with the time it took to complete these computational tasks. Summary: The above mainly demonstrates the usage of the microtime() function. |
