最近在研究PHP的Yii框架,很喜欢,碰到导出Excel的问题,研究了一下,就有了下面这篇文章,这篇文章主要给大家介绍了关于YII2框架中excel表格导出的相关资料,文中通过示例代码介绍的非常详细,需要的朋友可以参考借鉴,下面来一起看看吧。

前言

表格的导入导出是我们在日常开发中经常会遇到的一个功能,正巧在最近的项目中做到了关于表格输出的功能,并且之前用TP的时候也做过,所以想着趁着这次功能比较多样的机会整理一下,方便以后需要的时候,或者有需要的朋友们参考学习,下面话不多说了,来一起看看详细的介绍:

本文是基于YII2框架进行开发的,不同框架可能会需要更改

一.普通excel格式表格输出

先是最普通的导出.xls格式的表格。首先先看一下表格在网站的显示效果

这里可以看到整个表格一共是7列。下面来看代码的实现。

1.controller文件

//导出统计

public function actionStatistics(){
 //设置内存
 ini_set("memory_limit", "2048M");
 set_time_limit(0);

 //获取用户ID
 $id = Yii::$app->user->identity->getId();

 //去用户表获取用户信息
 $user = Employee::find()->where(['id'=>$id])->one();

 //获取传过来的信息(时间,公司ID之类的,根据需要查询资料生成表格)
 $params = Yii::$app->request->get();
 $objectPHPExcel = new \PHPExcel();

 //设置表格头的输出
 $objectPHPExcel->setActiveSheetIndex()->setCellValue('A1', '代理公司');
 $objectPHPExcel->setActiveSheetIndex()->setCellValue('B1', '收入');
 $objectPHPExcel->setActiveSheetIndex()->setCellValue('C1', '成本');
 $objectPHPExcel->setActiveSheetIndex()->setCellValue('D1', '稿件数');
 $objectPHPExcel->setActiveSheetIndex()->setCellValue('E1', '毛利(收入-成本)');
 $objectPHPExcel->setActiveSheetIndex()->setCellValue('F1', '毛利率(毛利/收入)*100%');
 $objectPHPExcel->setActiveSheetIndex()->setCellValue('G1', 'ARPU值');

 //跳转到recharge这个model文件的statistics方法去处理数据
 $data = Recharge::statistics($params);

 //指定开始输出数据的行数
 $n = 2;
 foreach ($data as $v){
 $objectPHPExcel->getActiveSheet()->setCellValue('A'.($n) ,$v['company_name']);
 $objectPHPExcel->getActiveSheet()->setCellValue('B'.($n) ,$v['company_cost']);
 $objectPHPExcel->getActiveSheet()->setCellValue('C'.($n) ,$v['cost']);
 $objectPHPExcel->getActiveSheet()->setCellValue('D'.($n) ,$v['num']);
 $objectPHPExcel->getActiveSheet()->setCellValue('E'.($n) ,$v['gross_margin']);
 $objectPHPExcel->getActiveSheet()->setCellValue('F'.($n) ,$v['gross_profit_rate']);
 $objectPHPExcel->getActiveSheet()->setCellValue('G'.($n) ,$v['arpu']);
 $n = $n +1;
 }
 ob_end_clean();
 ob_start();
 header('Content-Type : application/vnd.ms-excel');

 //设置输出文件名及格式
 header('Content-Disposition:attachment;filename="代理公司统计'.date("YmdHis").'.xls"');

 //导出.xls格式的话使用Excel5,若是想导出.xlsx需要使用Excel2007
 $objWriter= \PHPExcel_IOFactory::createWriter($objectPHPExcel,'Excel5');
 $objWriter->save('php://output');
 ob_end_flush();

 //清空数据缓存
 unset($data);
}

2.model文件

 <?php
 namespace app\models;//model层的命名空间
 //注意要引用yii的arrayhelper
 use yii\helpers\ArrayHelper;
 use Yii;
 class Recharge extends \yii\db\ActiveRecord
 {
 //excel一次导出条数
 const EXCEL_SIZE = 10000;
 
 //统计导出
 public static function statistics($params){

 //导出时间条件
 if(empty($params[&#39;min&#39;])){
 $date_max = date("Y-m-d",strtotime("-1 day"));
 $date_min = date("Y-m-d",strtotime("-31 day"));
 }else{
 $date_min = $params[&#39;min&#39;];
 $date_max = $params[&#39;max&#39;];
 }
 $where = &#39;&#39;;
 $where .= &#39;(`issue_date` BETWEEN &#39;.&#39;\&#39;&#39;.$date_min.&#39;\&#39;&#39;.&#39; AND &#39;.&#39;\&#39;&#39;.$date_max.&#39;\&#39;)&#39;;

 //查找指定数据
 $sql = &#39;select
 article.company_id,
 article.cost,
 article.company_cost
 from article WHERE article.status=2 AND &#39;.$where;
 $article = Article::findBySql($sql)->asArray()->all();
 $article = ArrayHelper::index($article,null,&#39;company_id&#39;);
 $companys = [];

 foreach ($article as $key=>$v){
 if(empty($key)){
 continue;
 }else{
 $number = count($v);
 $company = Company::find()->where([&#39;id&#39;=>$key])->select(&#39;name&#39;)->one();
 $company_name = $company[&#39;name&#39;];
 $cost = 0;
 $company_cost = 0;
 foreach ($v as $n){
 $cost += $n[&#39;cost&#39;];
 $company_cost += $n[&#39;company_cost&#39;];
 }
 if($company_cost == 0){
 $company_cost =1;
 }

 //这里注意,数据的存储顺序要和输出的表格里的顺序一样
 $companys[] = [
 //公司名
 &#39;company_name&#39; => $company_name,

 //收入
 &#39;company_cost&#39; => $company_cost,

 //成本
 &#39;cost&#39; => $cost,

 //稿件数
 &#39;num&#39; => $number,

 //毛利
 &#39;gross_margin&#39; => $company_cost-$cost,

 //毛利率
 &#39;gross_profit_rate&#39; => round(($company_cost-$cost)/$company_cost*100,2).&#39;%&#39;,

 //ARPU值
 &#39;arpu&#39; => round($company_cost/$number,2),
 ];
 }
 }
 return $companys;
 }
}


最终导出的效果(单元格大小导出后调整过)可以看到和网页显示的基本一样。

二.大数据表格导出

这时老板说了,我们不能只看总和的数据,最好是把详细数据也给导出来。既然老板发话了,那就做吧。还是按照第一种的方法去做,结果提示我php崩溃了,再试一次发现提示写入字节超出。打开php的配置文件php.ini

memory_limit = 128M

发现默认内存已经给到128M,应该是足够的了。于是我打开数据库一看,嚯!

接近83万条的数据进行查询并导出,可不是会出问题嘛!怎么办呢,于是我Google了一下,发现对于大数据(2万条以上)的导出,最好是以.csv的形式。不说废话,直接上代码

1.controller文件

//导出清单

public function actionInventory(){
 ini_set("memory_limit", "2048M");
 set_time_limit(0);
 $id = Yii::$app->user->identity->getId();
 $user = Employee::find()->where([&#39;id&#39;=>$id])->one();
 $params = Yii::$app->request->get();
 
 //类似的,跳转到recharge这个model文件里的inventory方法去处理数据
 $data = Recharge::inventory($params);
 
 //设置导出的文件名
 $fileName = iconv(&#39;utf-8&#39;, &#39;gbk&#39;, &#39;代理商统计清单&#39;.date("Y-m-d"));
 
 //设置表头
 $headlist = array(&#39;代理商&#39;,&#39;文章ID&#39;,&#39;文章标题&#39;,&#39;媒体&#39;,&#39;统计时间范围&#39;,&#39;状态&#39;,&#39;创建时间&#39;,&#39;审核时间&#39;,&#39;发稿时间&#39;,&#39;退稿时间&#39;,&#39;财务状态&#39;,&#39;成本&#39;,&#39;销售额&#39;,&#39;是否是预收款媒体类型&#39;,&#39;订单类别&#39;);
 header(&#39;Content-Type: application/vnd.ms-excel&#39;);
 
 //指明导出的格式
 header(&#39;Content-Disposition: attachment;filename="&#39;.$fileName.&#39;.csv"&#39;);
 header(&#39;Cache-Control: max-age=0&#39;);
 
 //打开PHP文件句柄,php://output 表示直接输出到浏览器
 $fp = fopen(&#39;php://output&#39;, &#39;a&#39;);
 
 //输出Excel列名信息
 foreach ($headlist as $key => $value) {
 //CSV的Excel支持GBK编码,一定要转换,否则乱码
 $headlist[$key] = iconv(&#39;utf-8&#39;, &#39;gbk&#39;, $value);
 }
 
 //将数据通过fputcsv写到文件句柄
 fputcsv($fp, $headlist);
 
 //每隔$limit行,刷新一下输出buffer,不要太大,也不要太小
 $limit = 100000;
 
 //逐行取出数据,不浪费内存
 foreach ($data as $k => $v) {
 //刷新一下输出buffer,防止由于数据过多造成问题
 if ($k % $limit == 0 && $k!=0) {
 ob_flush();
 flush();
 }
 $row = $data[$k];
 foreach ($row as $key => $value) {
 $row[$key] = iconv(&#39;utf-8&#39;, &#39;gbk&#39;, $value);
 }
 fputcsv($fp, $row);
 }
}

2.model文件(因为这部分我要处理的过多,所以只选择了部分代码),在查询数据那部分,因为要查的数据较多,所以可以结合我之前写的关于Mysql大数据查询处理的文章看一下

//清单导出

public static function inventory($params){
 //统计时间范围
 if(!empty($params[&#39;min&#39;]) && !empty($params[&#39;max&#39;])){
 $ti = strtotime($params[&#39;max&#39;])+3600*24;
 $max = date(&#39;Y-m-d&#39;,$ti);
 $time = $params[&#39;min&#39;].&#39;-&#39;.$params[&#39;max&#39;];
 $date_min = $params[&#39;min&#39;];
 $date_max = $max;
 }else{
 $date_max = date(&#39;Y-m-d&#39;);
 $date_min = date(&#39;Y-m-d&#39;,strtotime("-31 day"));
 $time = $date_min.&#39;-&#39;.$date_max;
 }
 //查询数据
 if($params[&#39;state&#39;] == 1){
 $where = &#39;&#39;;
 $where .= &#39; AND (`issue_date` BETWEEN &#39;.&#39;\&#39;&#39;.$date_min.&#39;\&#39;&#39;.&#39; AND &#39;.&#39;\&#39;&#39;.$date_max.&#39;\&#39;)&#39;;
 $map = &#39;select

 //查找的第一部分数据,使用asArray方法可以使我们查找的结果直接形成数组的形式,没有其他多余的数据占空间(注意:我这里查找分三部分是因为我要查三种不同的数据)
 $list1 = Article::findBySql($map)->asArray()->all();
 $where2 = &#39;&#39;;
 $where2 .= &#39; AND (`issue_date` BETWEEN &#39;.&#39;\&#39;&#39;.$date_min.&#39;\&#39;&#39;.&#39; AND &#39;.&#39;\&#39;&#39;.$date_max.&#39;\&#39;)&#39;;

3.导出结果

导出数量

导出的文件

基本上可以保证整个过程在2~4秒内处理完成

三.合并单元格

老板一看做的不错,说你顺便把充值统计的导出也做了把,想想我都是处理过这么多数据的人了,还不是分分钟搞定的事?来,上原型图

噗,一口老血,话都说了,搞吧。在做的时候我发现,这次的导出主要是要解决单元格合并的问题。经过查资料发现,PHP本身是实现不了单元格合并的,于是我打算通过phpexcel来实现

如果是使用PHPExcel的话,基本操作是这样的(合并A1到E1)

$objPHPExcel->getActiveSheet()->mergeCells(&#39;A1:E1&#39;);
// 表格填充内容
$objPHPExcel->getActiveSheet()->setCellValue(&#39;A1&#39;,&#39;The quick brown fox.&#39;);

结果

或者这样的(合并A1到E4)

$objPHPExcel->getActiveSheet()->mergeCells(&#39;A1:E4&#39;);
$objPHPExcel->getActiveSheet()->setCellValue(&#39;A1&#39;,&#39;The quick brown fox.&#39;);

结果

这样并不能满足我的要求,首先它是一个一个合并的,其次我要显示的充值金额下面的类型是会变化的,不可能固定写死,然后每次都更改。所以放弃了这种方法。

后来在小伙伴的帮助下尝试用html转存excel的方法

1.方法文件(因为我要每天定时执行,所以并没有写到controller层)

public function actionExcelRechargeStatistics(){

 //先定义一个excel文件
 $filename = date(&#39;【充值统计表】(&#39;.date(&#39;Y-m-d&#39;).&#39;导出)&#39;).".xls";
 header("Content-Type: application/vnd.ms-execl");
 header("Content-Type: application/vnd.ms-excel; charset=utf-8");
 header("Content-Disposition: attachment; filename=$filename");
 header("Pragma: no-cache");
 header("Expires: 0");
 //时间条件
 if(empty($params[&#39;min&#39;])){
 $time = date(&#39;Y-m-d&#39;,strtotime("+1 day"));
 $where = &#39; created < \&#39; &#39;.$time.&#39;\&#39;&#39;;
 }else{
 $time = $params[&#39;min&#39;]+3600*24;
 $time_end = $params[&#39;max&#39;]+3600*24;
 $where = &#39; created <= \&#39; &#39;.$time_end.&#39;\&#39; AND created >= \&#39;&#39;.$time.&#39;\&#39; &#39;;
 }
 //充值类型列表
 $recharge_type = Recharge::find()->asArray()->all();
 if(empty($recharge_type)){
 $rechargelist[0]= &#39;&#39;;
 }else{
 $rechargelist = ArrayHelper::map($recharge_type,&#39;id&#39;,&#39;recharge_name&#39;);
 }
 $rechargelist1 = $rechargelist;
 $count = count($rechargelist1);
 //使用html语句生成显示的格式
 $excel_content = &#39;<meta http-equiv="content-type" content="application/ms-excel; charset=utf-8"/>&#39;;
 $excel_content .= &#39;<table border="1" style="font-size:14px;">&#39;;
 $excel_content .= &#39;<thead>
   <tr>
   <th rowspan="2">ID</th>
   <th rowspan="2">公司名称</th>
   <th colspan=&#39;.$count.&#39;>充值金额</th>
   <th rowspan="2">充值大小</th>
   <th rowspan="2">实际消费</th>
   <th rowspan="2">当前余额</th>
   </tr>
   <tr>
  &#39;;
 foreach ($rechargelist1 as $v => $t){
 $excel_content .= &#39;<th colspan="1">&#39;.$t.&#39;</th>&#39;;
 }
 $excel_content .= &#39;</tr>
  </thead>&#39;;
 //查找最新的固化数据
 $search = RechargeStatistics::find()->where($where)->asArray()->all();
 if(!empty($search)){
 foreach ($search as $key => $value){
 $search[$key][&#39;recharge&#39;] = unserialize($value[&#39;recharge&#39;]);
 }
 }
 //html语句填充数据
 if(empty($search)){
 }else{
 foreach ($search as $k) {
 $excel_content .= &#39;<td>&#39;.$k[&#39;company_id&#39;].&#39;</td>&#39;;
 $excel_content .= &#39;<td>&#39;.$k[&#39;company_name&#39;].&#39;</td>&#39;;
 foreach ($rechargelist1 as $v=>$t){
 $price = 0;
 foreach ($k[&#39;recharge&#39;] as $q=>$w){
  if($w[&#39;recharge_id&#39;] == $v){
  $price = $w[&#39;price&#39;];
  break;
  }
 }
 $excel_content .= &#39;<td>&#39;.$price.&#39;</td>&#39;;
 }
 $excel_content .= &#39;<td>&#39;.$k[&#39;total&#39;].&#39;</td>&#39;;
 $excel_content .= &#39;<td>&#39;.$k[&#39;consume&#39;].&#39;</td>&#39;;
 $excel_content .= &#39;<td>&#39;.($k[&#39;total&#39;]-$k[&#39;consume&#39;]).&#39;</td></tr>&#39;;
 }
 }
 $excel_content .= &#39;</table>&#39;;
 echo $excel_content;
 die;
}

2.结果

到这里基本就完成所有的任务了!
