php8: 用call_user_func_array调用回调函数

一，代码:

<?php
  //调用函数一
  function afunc($b, $c) {
                echo "afunc:参数b:".$b.":<br/>";
                echo "afunc:参数c:".$c.":<br/>";
           }
   //调用函数二
  function bfunc($b, $c) {

      $sum = $b+$c;
      return $sum;
           }

  call_user_func_array('afunc', array("老王", "张三"));

  $sum = call_user_func_array('bfunc', array(11, 33));
  echo "bfunc:sum:".$sum.":<br/>";


            //调用类的静态方法和普通方法
            Class ClassA {
                 static function methoda($b, $c) {
                     $bc = $b + $c;
                     echo $bc;
                     return $bc;
                 }

                 function methodb($b, $c) {
                     $bc = $b + $c;
                     echo $bc;
                     return $bc;
                 }
            }

            $sum = call_user_func_array(array('ClassA','methoda'), array(111, 222));
            echo "ClassA methoda:".$sum.":<br/>";


           $obj = new ClassA;
           $sum = call_user_func_array(array($obj, "methodb"), array(11,33));
           echo "ClassA methodb:".$sum.":<br/>";


?>

 

二，测试效果:

afunc:参数b:老王:
afunc:参数c:张三:
bfunc:sum:44:
333ClassA methoda:333:
44ClassA methodb:44:
