數據查詢結果

轉化成三維數組，用戶id，課程id，詳細信息

因為查詢數據庫的結果被處理過，所以分頁不準確，可?通過有效的二維數組，獲取有效的$id，用$id來查詢數據庫并分頁

$where['total_time'] = array("EGT", 30);/* $count = $studycourseinfoModel->where($where)->count();import('ORG.Util.Page');$page = new Page($count,10);$show = $page->show(); *///$studycourseinfo = $studycourseinfoModel->where($where)->limit($page->firstRow.','.$page->listRows)->order('create_time asc')->select();//先查詢全部數據，下步篩選三維數字獲取有效數據$studycourseinfo = $studycourseinfoModel->where($where)->order('create_time asc')->select();foreach($studycourseinfo as $key=>$value){$studycourseinfo_new[$value['user_id']][$value['create_time']] = $studycourseinfo[$key];}$newStudyinfo = array();foreach($studycourseinfo_new as $keys=>$values){$startTime = 0;$count = 0;$tempStudyinfo = array();foreach($values as $k => $val){ if($startTime == 0){$startTime = $k;$count ++;$tempStudyinfo[] = $val;continue;} if($k - $startTime == 86400){$startTime = $k;$count ++;$tempStudyinfo[] = $val;}else{if($count >= 3){//有效數據$newStudyinfo[] = $tempStudyinfo;$tempStudyinfo = array();$count = 0;}else{//無效丟棄$tempStudyinfo = array();$count = 0;}$startTime = $k;$count ++;$tempStudyinfo[] = $val;}}if($count >= 3){//有效數據$newStudyinfo[] = $tempStudyinfo;$tempStudyinfo = array();$count = 0; }}//轉二維數組$i = 0;foreach ($newStudyinfo as $_k => $_val) {foreach ($_val as $_kay => $_val) {$_newStudyinfo[$i] = $_val;$i++;}}/* * 通過有效的二維數組，獲取有效的$id，用$id來查詢數據庫并分頁*/$id = array();foreach ($_newStudyinfo as $_ks => $_vals){$id[] = $_vals['id'];}$where['id'] = array('in',$id);$count = $studycourseinfoModel->where($where)->count();import('ORG.Util.Page');$page = new Page($count,20);$show = $page->show();$studycourseinfo_newss = $studycourseinfoModel->where($where)->limit($page->firstRow.','.$page->listRows)->order('create_time asc')->select();
