PHP calculation script execution time class php script parameters php script execution how to run php script

1. When optimizing code, the execution time of the script is a very important consideration. So how to use PHP to calculate the running time of the PHP script?

The following is a useful class recommended for everyone.

runtime.class.php

/**
* PHP script execution time calculation
*/
class runtime
{
var $StartTime = 0;
var $StopTime = 0;
function get_microtime()
                                                                                                                                            function get_microtime()                                                                         . {
                                                                            use using use using  -                                     $echo=false,$title='')
{
$spent = sprintf('%.4f',round(($this->StopTime - $this->StartTime) * 1000, 1)/1000) ; If ($ echo) {
echo $ table. "Execution time: {$ Spent} second & lt; br/& gt;";
} else {
Return $ spent;
                $this->StartTime = 0;
                  $this->StopTime = 0;
                                 ‐         ‐              );
$a = 0;
for($i=0; $i<100000; $i++)
{
$a *= $i;
}
$runtime->stop();
$spent_time = $runtime->spent($echo=true, 'test script');
$runtime->clear();


Test results:





The above introduces the PHP script execution time calculation class, including PHP and script content. I hope it will be helpful to friends who are interested in PHP tutorials.
