laravel 中使用反射得到类的所有方法
以Carbon这个时间处理库为例
$class = new \ReflectionClass('Carbon\Carbon');//获取反射类
$methods = $class->getMethods();//获取反射类的所有的方法
//各个方法的处理效果
foreach ($methods as $key => $value) {
$hasMethod[] = $value->name;
if (ends_with($value->name, 'String') && starts_with($value->name, 'to'))
{
echo $value->name . '() ---输出格式为：' . PHP_EOL;
echo Carbon::now()->{$value->name}() . PHP_EOL;
}
}
dd($hasMethod);
结果：

Dec 6, 2018

IOC是一种思想，DI是实现IOC的一种方法
通过类名与方法，根据反射来实现
$class = new \ReflectionClass('Carbon\Carbon');//获取反射类
$obj = $class->newInstance();//实例化对象
echo $obj->now()->toDateString() . PHP_EOL;
echo $obj->now()->toDateTimeString() . PHP_EOL;
echo $obj->now()->toTimeString() . PHP_EOL;```
结果：
2018-12-06
2018-12-06 11:35:41
11:35:41
