Getting PHP execution time |
Sometimes, I need to optimize pieces of code, especially mysql query execution time. But how to check if some piece of code is faster than other? I use PHP function microtime(). Thats how it looks like:
$code_starts = microtime(true);
...
<some code, sql query etc...>
...
$code_ends = microtime(true);
$execution_time = $code_ends - $code_starts;
echo "Done in: ".$execution_time." s";
