计时器

一个可以被静态或动态调用的计时器类。

源代码: support/blob/master/src/Timer.php

方法

这些都是方法

Timer::start();
Timer::stop();
Timer::isStarted();
Timer::isStopped();
Timer::elapsed(); // returns a formatted value 9.0192
Timer::elapsedRaw(); // returns a double 9.019223049023
Timer::setFormat(default = '%.4f');

你可以命名你的计时器并且可以运行多个

Timer::start('mary');
Timer::stop('mary');
Timer::elapsed('mary');

示例

Timer::start();
Timer::start('2nd timer');

var_dump("started: " . (Timer::isStarted() ? 'yes' : 'no'));
var_dump("stopped: " . (Timer::isStopped() ? 'yes' : 'no'));

sleep(5);

Timer::stop();

var_dump("started: " . (Timer::isStarted() ? 'yes' : 'no'));
var_dump("stopped: " . (Timer::isStopped() ? 'yes' : 'no'));
var_dump("elapsed: " . Timer::elapsed());
var_dump("raw: " . Timer::elapsedRaw());

sleep(2);

var_dump("'2nd timer' started: " . (Timer::isStarted('2nd timer') ? 'yes' : 'no'));
var_dump("'2nd timer' stopped: " . (Timer::isStopped('2nd timer') ? 'yes' : 'no'));
var_dump("'2nd timer' elapsed: " . Timer::elapsed('2nd timer'));
var_dump("'2nd timer' raw: " . Timer::elapsedRaw('2nd timer'));

sleep(2);

Timer::stop('2nd timer');

var_dump("'2nd timer' started: " . (Timer::isStarted('2nd timer') ? 'yes' : 'no'));
var_dump("'2nd timer' stopped: " . (Timer::isStopped('2nd timer') ? 'yes' : 'no'));
var_dump("'2nd timer' elapsed: " . Timer::elapsed('2nd timer'));
var_dump("'2nd timer' raw: " . Timer::elapsedRaw('2nd timer'));

Timer::setFormat('%.8f');
var_dump("'2nd timer' elapsed 8 decimals: " . Timer::elapsed('2nd timer'));

/// 你可以实例化它并重新开始

$t = new Timer;
$t->start();
sleep(3);
$t->stop();
var_dump("elapsed dynamic: " . $t->elapsed());

这应该给出这个结果

string(12) "started: yes"
string(11) "stopped: no"
string(11) "started: no"
string(12) "stopped: yes"
string(15) "elapsed: 5.0004"
string(20) "raw: 5.0005040168762"
string(24) "'2nd timer' started: yes"
string(23) "'2nd timer' stopped: no"
string(27) "'2nd timer' elapsed: 7.0008"
string(32) "'2nd timer' raw: 7.0008120536804"
string(23) "'2nd timer' started: no"
string(24) "'2nd timer' stopped: yes"
string(27) "'2nd timer' elapsed: 9.0011"
string(32) "'2nd timer' raw: 9.0010931491852"
string(42) "'2nd timer' elapsed 8 decimals: 9.00113106"
string(27) "elapsed dynamic: 3.00018883"
