Measure execution time in PHP

  • 772

I am trying to get the execution time of an operation that runs iteratively, but when trying to compare, I get 0 seconds.

$startedAt = time();
for ($i = 0; $i < 10000; $i++) {
    // Solo como código demostrativo.
    preg_match('/^0{3}\b/', $number);
}
$finishedAt = time();

echo 'Tiempo: ' . ($finishedAt - $startedAt);

Searching in php.net I don't find an alternative function, is there another solution?

    You can do it with microtime

        $start = microtime(true);

    for ($i = 0; $i < 10000; $i++) {
// Solo como código demostrativo.
 preg_match('/^0{3}\b/', $number); }

    $end = microtime(true);
    $time = $end-$start;
    echo "execute time {$time}";
