How PHP Gets the page execution time (recommended) _php instance

Some loop code, sometimes to know the time of the page execution, you can add the following lines of code to the page head and tail:

Head:

<?php

Tail:

$etime =microtime (TRUE);//Get the time when the program execution ends
$total = $etime-$stime;  Calculate the difference value
?>

Final output:

echo "<br/> Current page Execution time: {$total} seconds";

The above is a small set of PHP to introduce the implementation of the time page of the method (recommended), I hope to help you, if you have any questions welcome to my message, small series will promptly reply to everyone, here also thank you for your support cloud Habitat community site!
