PHP闭包函数传参及使用外部变量的方法，php变量
本文实例讲述了PHP闭包函数传参及使用外部变量的方法。分享给大家供大家参考，具体如下：
在Laravel控制器写两个方法，一个是在内部创建一个闭包函数，一个是执行传过来的闭包函数，测试闭包的写法，use使用外部变量，及闭包函数的传参。如下：
//测试闭包传参及use使用外部变量
public function testClosure($t1, $t2)
{
$closure = function ($param1, $param2) use ($t1, $t2) {
echo $param1.$param2.$t1.$t2;
};
$this->execClosure('test.closure', $closure);
}
//执行闭包函数
protected function execClosure($name, Closure $closure)
{
echo 'Closure func name:'.$name;
echo '<br>';
$closure('p1', 'p2');
}
在routes.php添加路由：
复制代码 代码如下:Route::get('/test/closure/{t1}/{t2}',['uses'=>'TestController@testClosure']);
访问www.example.com/test/closure/hehe1/hehe2
浏览器输出结果：
Closure func name:test.closure p1p2hehe1hehe2
