PHP 5.3及以上版本的简单基准测试套件。

基本用法

    use mindplay\benchpress\Benchmark;

    $bench = new Benchmark();

    // Benchmark a function and get the result immediately:

    $time = $bench->mark(
        function () {
            // do the work...
        }
    );

带有报告

    use mindplay\benchpress\Benchmark;

    $bench = new Benchmark();

    // Queue up functions to be benchmarked:

    $bench->add(
        "Description of work",
        function () {
            // do the work...
        }
    );

    $bench->add(...);
    $bench->add(...);
    $bench->add(...);

    // Run the queued functions and generate a report:

    $bench->run();
