Example usage

Benchmark a function

``` php <?php $forBenchmark = Benchmark::time(function () { for ($i = 0; $i < 100; $i++) { // } });, <sub>(*2)</sub>

$whileBenchmark = Benchmark::time(function () { $i = 0; while ($i < 100) { $i++; } });, <sub>(*3)</sub>

echo $forBenchmark->compare($whileBenchmark);, <sub>(*4)</sub>

### Benchmark a block of code
``` php
<?php
$forBenchmark = Benchmark::begin();
for ($i = 0; $i < 100; $i++) {
    //
}
$forBenchmark->stop();

$whileBenchmark = Benchmark::begin();
$i = 0;
while ($i < 100) {
    $i++;
}
$whileBenchmark->stop();

echo $forBenchmark->compare($whileBenchmark);

Nested benchmarks

``` php <?php $calculateBenchmark = Benchmark::begin(); for ($i = 0; $i < 1000; $i++) { pow($i, $i); }, <sub>(*5)</sub>

$databaseBenchmark = Benchmark::begin(); // do some random database stuff $databaseBenchmark->stop(); $calculateBenchmark->stop();, <sub>(*6)</sub>
