While working with José ABCD (that’s not his last name… he likes to remain unknown) we were talking about two ways of solving a problem un PHP and which would be the best in terms of speed. To solve this, we decided to use microtime(). This is what we did:
Code
$cicles = 5000; // Number of cicles
$totalTime = 0; // Total time, set to 0
for ($i=0; $i<$cicles; $i++){ // This for gets run for $cicles times
$timeInit = microtime(); // Initial time
## código a probar aquí ## // This is the code to test, it can be a function or several lines of code
$timeEnd = microtime(); // End time
// Next we process time to get a total amout of time during all $cicles
$timeInit = explode(" ", $timeInit);
$timeInit = (double) $timeInit[0] + $timeInit[1];
$timeEnd = explode(" ", $timeEnd);
$timeEnd = (double) $timeEnd[0] + $timeEnd[1];
$totalTime += ($timeEnd - $timeInit);
}
$timeAvg = $totalTime / $cicles; // Average time
// We print our results
echo "<div>";
echo "Total = ".$totalTime."<br>";
echo "Avg = ".$timeAvg."<br>--<br>";
echo "</div>";
