Some loop code, sometimes you want to know the execution time of the page, you can add the following lines of code to the head and tail of the page:
Head:
<?php $stime=microtime(true);
Tail:
$etime=microtime(true);//获取程序执行结束的时间 $total=$etime-$stime; //计算差值 ?>
Final output:
echo "<br />当前页面执行时间为：{$total} 秒";
