因为查询数据库的结果被处理过，所以分页不准确，可 通过有效的二维数组，获取有效的$id，用$id来查询数据库并分页

$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();//先查询全部数据，下步筛选三维数字获取有效数据$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){//有效数据$newStudyinfo[] = $tempStudyinfo;$tempStudyinfo = array();$count = 0;}else{//无效丢弃$tempStudyinfo = array();$count = 0;}$startTime = $k;$count ++;$tempStudyinfo[] = $val;}}if($count >= 3){//有效数据$newStudyinfo[] = $tempStudyinfo;$tempStudyinfo = array();$count = 0;	}}//转二维数组$i = 0;foreach ($newStudyinfo as $_k => $_val) {foreach ($_val as $_kay => $_val) {$_newStudyinfo[$i] = $_val;$i++;}}/* * 通过有效的二维数组，获取有效的$id，用$id来查询数据库并分页*/$id = array();foreach ($_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();
