PHP records page code execution time_PHP tutorial

To record the code execution time in the page in php, we only use the microtime function to generate the time, and then subtract the start and end time at the end to solve the problem.

​

Core Code

The code is as follows

代码如下
$t1 = microtime(true); // ... 执行代码 ... $t2 = microtime(true); echo '耗时'.round($t2-$t1,3).'秒';

$t1 = microtime(true);
// ...execute code ...
$t2 = microtime(true);
echo 'Time consuming'.round($t2-$t1,3).'Seconds';

The above is the core code, let’s introduce it in detail

代码如下
$start_time=microtime(true); //获取程序开始执行的时间 echo "hello world! "; //你执行的代码  $end_time=microtime(true);//获取程序执行结束的时间  $total=$end_time-$start_time; //计算差值  echo "此php文件中代码执行了{$total}秒"; ?>

The code is as follows
$start_time=microtime(true); //Get the time when the program starts executing echo "hello world! "; //The code you execute $end_time=microtime(true);//Get the time when program execution ends $total=$end_time-$start_time; //Calculate the difference echo "The code in this php file was executed for {$total} seconds"; ?>
