 * This example shows using multiple stop watches in the same program.
 * If we want to use multiple watches, we must provide unique name all of them.
 * Steps involved are:
 * - Add watches by any of following methods
 * - Call `addWatch` multiple times, with name of watch as parameter, or
 * - Call `addWatches` and pass an array of name of watches as parameter.
 * - Further operation is same as in `simplewatch` and `pauseDemo` example. However this time, we need to pass
 * watch name to all the methods.

// Load Composer auto loader
require_once "../vendor/autoload.php";

// Create an instance of StopWatch
$stopWatch = new StopWatch();

// Initialize the watches.
$stopWatch->addWatches(["a", "b", "c"]);
// We could also use '$stopWatch->addWatch("name")' individually.

$operatorA = 0;
$operatorB = 0;
$operatorC = 0;

for (
$i = 1; $i <= 10; $i++) {
// Following code block represent one operation, which needs to be measured.
    for (
$a = 0; $a < 10000; $a++) {

// Following code block represent another operation, which needs to be measured separately.
    for (
$b = 0; $b < 10000; $b++) {

// One more operation, independent of above operations needs to be measured.
    for (
$c = 0; $c < 10000; $c++) {

printf("Time taken in block 'a': %f seconds.\n", $stopWatch->getTime("a"));
printf("Time taken in block 'b': %f seconds.\n", $stopWatch->getTime("b"));
printf("Time taken in block 'c': %f seconds.\n", $stopWatch->getTime("c"));
