一个用于精确时间测量的 PHP 类。

基本用法

$s = new StopWatch();

$s->start();
// do something...
$s->stop(); 

// printing result
echo $s->getResult(); // (float) 3.6618700027466
// or
echo $s; // to string conversion provides humanized output, e.g. "0:03.662"

常规用法

$s = new StopWatch();

$s->start("total");

  $s->start("parsing_request");
  // do something
  $s->stop("parsing_request");

  $s->start("preparing_data");
  // do something
  $s->stop("preparing_data");

  $s->start("rendering");
  
    // do something

    $s->start("rendering_partial_template");
    // do something
    $s->stop("rendering_partial_template");

    $s->start("rendering_partial_template");
    // do something
    $s->stop("rendering_partial_template");

  $s->stop("rendering");

$s->stop("total");

打印结果

echo $s->getResult("total"); // 0.034516096115112
echo $s->getResult("rendering"); // 0.017526865005493

对于整体报告，有一个特殊的方法

echo $s->getPrintableOutput();

输出非常酷 :)
