例子：三維數組

[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入門課程第一節"

["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) "今天課程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) "今天課程3"

["class_id"] => NULL

["starttime"] => string(19) "2019-04-22 09:57:24"

["endtime"] => string(19) "2019-04-22 10:27:24"

}

}

}

最終效果：
