例子：三维数组

  [0] => array(19) {
    [0] => array(47) {
      ["pid"] => string(3) "291"
      ["bigclass"] => NULL
      ["title"] => string(4) "Html"
      ["class_id"] => string(1) "0"
      ["starttime"] => NULL
      ["endtime"] => NULL

    }
    [1] => array(47) {
      ["pid"] => string(3) "291"
      ["bigclass"] => string(3) "566"
      ["title"] => string(29) "HTML+css入门课程第一节"
      ["class_id"] => string(1) "0"
      ["starttime"] => string(19) "2020-07-14 09:36:36"
      ["endtime"] => string(19) "2020-07-14 11:16:36"
    }
  }
  [1] => array(14) {
    [0] => array(47) {
      ["pid"] => string(3) "128"
      ["bigclass"] => NULL
      ["title"] => string(9) "第一章"
      ["class_id"] => NULL
      ["starttime"] => NULL
      ["endtime"] => NULL
    }
    [1] => array(47) {
      ["pid"] => string(3) "128"
      ["bigclass"] => string(3) "288"
      ["title"] => string(13) "今天课程2"
      ["class_id"] => NULL
      ["starttime"] => string(19) "2019-04-18 00:00:00"
      ["endtime"] => string(19) "2019-04-18 00:30:00"
    }
    [2] => array(47) {
      ["pid"] => string(3) "128"
      ["bigclass"] => string(3) "288"
      ["title"] => string(13) "今天课程3"
      ["class_id"] => NULL
