()平衡

Question

由于某种原因,我收到以下行的语法错误,括号不平衡,我没有看到原因.

if(isset($this->uri->segment(3)) AND ((empty($this->uri->segment(3))||($this->uri->segment(3) === FALSE)||(trim($this->uri->segment(3)) == '')))

Answer 1

if(
  isset(
    $this->uri->segment(3)
  ) AND (
    (
      empty(
        $this->uri->segment(3)
      )||(
        $this->uri->segment(3) === FALSE
      )||(
        trim(
          $this->uri->segment(3)
        ) == ''
      )
    )
  )

你忘了关闭你的if.
