Calculate how long a PHP script takes to run
Now this one is simple, everything is already in place in PHP, first just add this line before the code you want to measure. ``` $time_start = microtime(true); ``` Then after your code just use this block and it will output the time in seconds it took to run the code between the 2 blocks. ``` $time_end = microtime(true); echo "<div>Took ".($time_end - $time_start)." seconds</div>"; ```
