`PHP` 计算时间差
===========

[](#php-计算时间差)

关于仓库里面的代码
---------

[](#关于仓库里面的代码)

写程序的时候可能会想计算两个时间点之间的代码执行的时间，这时就需要计算时间差了。`PHP`里面，有 `hrtime`（要求`PHP`版本大于或等于`7.3.0`）或者`microtime`函数可以用来获取当前的精确时间， 从而能计算短时间之间的间隔。这个仓库里面有个`Timer`类便是用来实现这种需求的，里面根据运行环境 自动使用`hrtime`或者`microtime`来进行时间的记录。

使用说明
----

[](#使用说明)

通过实例化`Timer`类来获得当前的时间，然后调用对象方法获得两个时间对象的时间差。示例：

```
$t0 = new Timer\Timer();
for ($i = 0; $i < 10000000; $i++) {
    $x = mt_rand();
}
$t1 = new Timer\Timer();
// 输出时间差，t1 - t0
echo $t1->sub($t0);
echo PHP_EOL;
```

示例代码输出类似：

```
0.772363515

```

可以通过运行仓库的`php index.php`来看示例效果。
