call_user_func 具体使用方法,实例说明

<?php

class Person{
    public $name="jack";
    
    public static function say(){
        echo "ok";
    }
    public static function say2($words){
        echo $words;
    }
    
    public function name(){
        echo $this->name;
    }
    public function call($num){
        echo $this->name." call ".$num;
    } 
}

function get_date($format){
    echo date($format);
}


$jack=new Person;
//1.调用对象 方法
call_user_func([$jack,"name"]);

//2.调用对象 方法带参数
call_user_func([$jack,"call"],'119');

//3.调用类的静态方法
call_user_func(['Person',"say"]);

//4.调用类的静态方法带参数
call_user_func(['Person',"say2"],'hello world');

//5.直接调用全局方法(当然也可以不带参数)
call_user_func("get_date",'Y-m-d');

//6.调用匿名函数(当然也可以不带参数)
call_user_func(function($event){
    echo "anonymous function".$event;
},'1');
