<?php /* * The example shows how to pause the timer for measuring time at different stages. * Once watch is started, we can call `pause` method to pause the watch. * If watch is paused, we can start it again to start timer. In that case, time will be added to timer. */ use Phpreboot\Stopwatch\StopWatch; // Create an instance of StopWatch $stopWatch = new StopWatch(); $innerIterator = 0; for ($i = 1; $i <= 10; $i++) { printf("Iteration %d starting.\n", $i); $stopWatch->start(); for ($j = 0; $j < 1000; $j++) { $innerIterator++; } $stopWatch->pause(); printf("Iteration %d watch stopped, not other task is starting..\n", $i); for ($k = 0; $k < 1000; $k++) { $timeWaster = $k; } } printf("Time taken by first loop (\$j), for %d iterations was: %f seconds.\n", $innerIterator, $stopWatch->getTime());
