  谢谢，已经解决了，我是在getHdSize方法中使用的echo，应该是return。

  <?php
  
  class Computer{
      public $cpu ="amd";
      public $mainboard="华硕";
      private $hd=5000;
  
      public function game($gameName=''){
          if($this->getHdSize() <1024){
              echo "硬盘太小";
              return false;
          }return true;
      }
  
      public function job($work="工作"){
          echo ($this->game());
  
      }
      private function getHdSize(){
          return $this->hd;
      }
  
  }
  
  $computer=new Computer();
  
  $computer->job();
