### 对于少量数据采用Excel导入导出 - 导入 ~~~ <form id="importform" class="form-horizontal form" action="" method="post" enctype="multipart/form-data"> <div class="form-group"> <label class="col-sm-2 control-label must">EXCEL</label> <div class="col-sm-5" style="padding-right:0;" > <input type="file" name="excelfile" class="form-control" /> <span class="help-block">选择excel文件</span> </div> </div> <div class='form-group'> <div class="col-sm-12"> <div class="modal-footer"> <button type="submit" class="btn btn-primary" name="cancelsend" value="yes">确认导入</button> </div> </div> </div> </form> ~~~ php处理 ~~~ if ($_W['ispost']) { $rows = m('excel')->import('excelfile'); $time = time(); foreach ($rows as $rownum => $col) { $data = array( 'uniacid' => $_W['uniacid'], 'createtime' => $time, 'category' => trim($col[0]), 'orderid' => trim($col[1]), 'isuse' => trim($col[2]) ); if (empty($col[0])) { continue; } pdo_insert('ewei',$data); } $this->message('导入成功!',webUrl(''), ''); } ~~~ - 导出模板,调用以下方法即可 ~~~ public function import() { $columns = array(); $columns[] = array('title' => '物流类别', 'field' => '', 'width' => 32); $columns[] = array('title' => '物流单号', 'field' => '', 'width' => 32); $columns[] = array('title' => '是否使用', 'field' => '', 'width' => 32); m('excel')->temp('文件名'. date('Y-m-d-H-i', time()), $columns); } ~~~ - 导出excel ~~~ <button type="submit" name="export_order" value="1" class="btn btn-primary btn-sm">导出订单</button> //$list是数据 if ($_GPC['export_order'] == 1) { $earr = array(); foreach($list as $v){ $earr[]=array( 'openid' => $v['openid'], 'price' => $v['price'], 'mobile'=> $v['mobile'], ); } $titlearr = array( array('title' => 'openid', 'field' => 'openid', 'width' => 24), array('title' => '手机号', 'field' => 'mobile', 'width' => 12), array('title' => '智慧卡金额', 'field' => 'price', 'width' => 12), ); m('excel')->export($earr, array('title' => '订单-' . date('Y-m-d-H-i', time()), 'columns' => $titlearr)); } ~~~ ### 大数据导入导出 #### csv导出大数据使用方法fputcsv()函数; #### 步骤如下 - 计算出总数据数,大概测试出每次可导出数据量,比如1000条可导出,内存不会溢出;并设置初始导出;下面语句都是需要的,输出缓存,并且保证不会中文乱码 ~~~ $totalcount = pdo_fetchcolumn("select count(id) from ".tablename('ewei_shop_order').' where uniacid='.$uniacid); $pagecount = 1000; set_time_limit(0); header("Content-type:application/vnd.ms-excel"); header("Content-Disposition:attachment;filename=全部订单-".date('Y-m-d-H-i-s').".csv"); ob_start(); ob_end_clean(); echo "\xEF\xBB\xBF"; $head = array('openid','粉丝昵称'); $fp = fopen('php://output', 'a'); fputcsv($fp, $head); for($i=0;$i<intval($totalcount/$pagecount)+1;$i++){ $sql=""; $sql .= ' LIMIT ' . strval($i*$pagecount) .
