最近的項目作到關於表格輸出的功能，以前用TP的時候也作過，趁着此次功能比較多樣的機會整理一下php

本文是基於YII2框架進行開發的，不一樣框架可能會須要更改html

一.普通excel格式表格輸出

先是最普通的導出.xls格式的表格。首先先看一下表格在網站的顯示效果sql

這裏能夠看到整個表格一共是7列。下面來看代碼的實現。數據庫

1.controller文件數組

//導出統計
    public function actionStatistics(){
        //設置內存
        ini_set("memory_limit", "2048M");
        set_time_limit(0);

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

        //去用戶表獲取用戶信息
        $user       =   Employee::find()->where(['id'=>$id])->one();

        //獲取傳過來的信息（時間，公司ID之類的，根據須要查詢資料生成表格）
        $params     =   Yii::$app->request->get();
        $objectPHPExcel = new \PHPExcel();

        //設置表格頭的輸出
        $objectPHPExcel->setActiveSheetIndex()->setCellValue('A1', '代理公司');
        $objectPHPExcel->setActiveSheetIndex()->setCellValue('B1', '收入');
        $objectPHPExcel->setActiveSheetIndex()->setCellValue('C1', '成本');
        $objectPHPExcel->setActiveSheetIndex()->setCellValue('D1', '稿件數');
        $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');

        //跳轉到recharge這個model文件的statistics方法去處理數據
        $data = Recharge::statistics($params);

        //指定開始輸出數據的行數
        $n = 2;
        foreach ($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');

        //設置輸出文件名及格式
        header('Content-Disposition:attachment;filename="代理公司統計'.date("YmdHis").'.xls"');

        //導出.xls格式的話使用Excel5,如果想導出.xlsx須要使用Excel2007
        $objWriter= \PHPExcel_IOFactory::createWriter($objectPHPExcel,'Excel5');
        $objWriter->save('php://output');
        ob_end_flush();

        //清空數據緩存
        unset($data);
    }

2.model文件瀏覽器

<?php
namespace app\models;//model層的命名空間


//注意要引用yii的arrayhelper
use yii\helpers\ArrayHelper;
use Yii;

class Recharge extends \yii\db\ActiveRecord
{

    //excel一次導出條數
    const EXCEL_SIZE = 10000;

    //統計導出
    public static function statistics($params){

        //導出時間條件
        if(empty($params['min'])){
            $date_max = date("Y-m-d",strtotime("-1 day"));
            $date_min = date("Y-m-d",strtotime("-31 day"));
        }else{
            $date_min = $params['min'];
            $date_max = $params['max'];
        }
        $where = '';
        $where .= '(`issue_date` BETWEEN '.'\''.$date_min.'\''.' AND '.'\''.$date_max.'\')';

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

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

                //這裏注意，數據的存儲順序要和輸出的表格裏的順序同樣
                $companys[] = [
                    //公司名
                    'company_name'      =>  $company_name,

                    //收入
                    'company_cost'      =>  $company_cost,

                    //成本
                    'cost'              =>  $cost,

                    //稿件數
                    'num'               =>  $number,

                    //毛利
                    'gross_margin'      =>  $company_cost-$cost,

                    //毛利率
                    'gross_profit_rate' =>  round(($company_cost-$cost)/$company_cost*100,2).'%',

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

最終導出的效果（單元格大小導出後調整過）能夠看到和網頁顯示的基本同樣。緩存

二.大數據表格導出

這時老闆說了，咱們不能只看總和的數據，最好是把詳細數據也給導出來。既然老闆發話了，那就作吧。仍是按照第一種的方法去作，結果提示我php崩潰了，再試一次發現提示寫入字節超出。打開php的配置文件php.iniapp

memory_limit = 128M

發現默認內存已經給到128M，應該是足夠的了。因而我打開數據庫一看，嚯！框架

接近83萬條的數據進行查詢並導出，可不是會出問題嘛！怎麼辦呢，因而我Google了一下，發現對於大數據(2萬條以上)的導出，最好是以.csv的形式。不說廢話，直接上代碼yii

1.controller文件

 //導出清單
    public function actionInventory(){
        ini_set("memory_limit", "2048M");
        set_time_limit(0);
        $id         =   Yii::$app->user->identity->getId();
        $user       =   Employee::find()->where(['id'=>$id])->one();
        $params     =   Yii::$app->request->get();
        
		//相似的，跳轉到recharge這個model文件裏的inventory方法去處理數據
        $data       =   Recharge::inventory($params);
        
		//設置導出的文件名
        $fileName   =   iconv('utf-8', 'gbk', '代理商統計清單'.date("Y-m-d"));
        
		//設置表頭
        $headlist   =   array('代理商','文章ID','文章標題','媒體','統計時間範圍','狀態','建立時間','審覈時間','發稿時間','退稿時間','財務狀態','成本','銷售額','是不是預收款媒體類型','訂單類別');
        header('Content-Type: application/vnd.ms-excel');
        
		//指明導出的格式
        header('Content-Disposition: attachment;filename="'.$fileName.'.csv"');
        header('Cache-Control: max-age=0');
        
		//打開PHP文件句柄,php://output 表示直接輸出到瀏覽器
        $fp = fopen('php://output', 'a');
        
		//輸出Excel列名信息
        foreach ($headlist as $key => $value) {
            //CSV的Excel支持GBK編碼，必定要轉換，不然亂碼
            $headlist[$key] = iconv('utf-8', 'gbk', $value);
        }
        
		//將數據經過fputcsv寫到文件句柄
        fputcsv($fp, $headlist);
        
		//每隔$limit行，刷新一下輸出buffer，不要太大，也不要過小
        $limit = 100000;
        
		//逐行取出數據，不浪費內存
        foreach ($data as $k => $v) {
            //刷新一下輸出buffer，防止因爲數據過多形成問題
            if ($k % $limit == 0 && $k!=0) {
                ob_flush();
                flush();
            }
            $row = $data[$k];
            foreach ($row as $key => $value) {
                $row[$key] = iconv('utf-8', 'gbk', $value);
            }
            fputcsv($fp, $row);
        }
    }

2.model文件（由於這部分我要處理的過多，因此只選擇了部分代碼），在查詢數據那部分，由於要查的數據較多，因此能夠結合我以前寫的關於Mysql大數據查詢處理的文章看一下

PHP

//清單導出
    public static function inventory($params){
        //統計時間範圍
        if(!empty($params['min']) && !empty($params['max'])){
            $ti = strtotime($params['max'])+3600*24;
            $max = date('Y-m-d',$ti);
            $time = $params['min'].'-'.$params['max'];
            $date_min = $params['min'];
            $date_max = $max;
        }else{
            $date_max = date('Y-m-d');
            $date_min = date('Y-m-d',strtotime("-31 day"));
            $time = $date_min.'-'.$date_max;
        }
        //查詢數據
        if($params['state'] == 1){
            $where  = '';
            $where .= ' AND (`issue_date` BETWEEN '.'\''.$date_min.'\''.' AND '.'\''.$date_max.'\')';
            $map = 'select
                     company.name,

            //查找的第一部分數據，使用asArray方法可使咱們查找的結果直接造成數組的形式，沒有其餘多餘的數據佔空間（注意：我這裏查找分三部分是由於我要查三種不一樣的數據）
            $list1   = Article::findBySql($map)->asArray()->all();
            $where2  = '';
            $where2 .= ' AND (`issue_date` BETWEEN '.'\''.$date_min.'\''.' AND '.'\''.$date_max.'\')';

        }
        return $inventory;
    }

3.導出結果

導出數量

導出的文件

基本上能夠保證整個過程在2~4秒內處理完成

三.合併單元格

老闆一看作的不錯，說你順便把充值統計的導出也作了把，想一想我都是處理過這麼多數據的人了，還不是分分鐘搞定的事？來，上原型圖

噗，一口老血，話都說了，搞吧。在作的時候我發現，此次的導出主要是要解決單元格合併的問題。通過查資料發現，PHP自己是實現不了單元格合併的，因而我打算經過phpexcel來實現

若是是使用PHPExcel的話，基本操做是這樣的（合併A1到E1）

$objPHPExcel->getActiveSheet()->mergeCells('A1:E1');
// 表格填充內容
$objPHPExcel->getActiveSheet()->setCellValue('A1','The quick brown fox.');

結果

或者這樣的（合併A1到E4）

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

結果

這樣並不能知足個人要求，首先它是一個一個合併的，其次我要顯示的充值金額下面的類型是會變化的，不可能固定寫死，而後每次都更改。因此放棄了這種方法。

後來在小夥伴的幫助下嘗試用html轉存excel的方法

1.方法文件（由於我要天天定時執行，因此並無寫到controller層）

public function actionExcelRechargeStatistics(){
        //先定義一個excel文件
        $filename   =   date('【充值統計表】('.date('Y-m-d').'導出)').".xls";
        header("Content-Type: application/vnd.ms-execl");
        header("Content-Type: application/vnd.ms-excel; charset=utf-8");
        header("Content-Disposition: attachment; filename=$filename");
        header("Pragma: no-cache");
        header("Expires: 0");
        //時間條件
        if(empty($params['min'])){
            $time       =   date('Y-m-d',strtotime("+1 day"));
            $where      =   ' created < \' '.$time.'\'';
        }else{
            $time       =   $params['min']+3600*24;
            $time_end   =   $params['max']+3600*24;
            $where      =   ' created <= \' '.$time_end.'\' AND created >= \''.$time.'\' ';
        }
        //充值類型列表
        $recharge_type  =   Recharge::find()->asArray()->all();
        if(empty($recharge_type)){
            $rechargelist[0]=   '';
        }else{
            $rechargelist   =   ArrayHelper::map($recharge_type,'id','recharge_name');
        }
        $rechargelist1      =   $rechargelist;
        $count              =   count($rechargelist1);
        //使用html語句生成顯示的格式
        $excel_content      =   '<meta http-equiv="content-type" content="application/ms-excel; charset=utf-8"/>';
        $excel_content     .=   '<table border="1" style="font-size:14px;">';
        $excel_content     .=   '<thead>
                                     <tr>
                                        <th rowspan="2">ID</th>
                                        <th rowspan="2">公司名稱</th>
                                        <th colspan='.$count.'>充值金額</th>
                                        <th rowspan="2">充值大小</th>
                                        <th rowspan="2">實際消費</th>
                                        <th rowspan="2">當前餘額</th>
                                     </tr>
                                     <tr>
                                 ';
        foreach ($rechargelist1 as $v => $t){
                $excel_content     .=   '<th colspan="1">'.$t.'</th>';
        }
        $excel_content     .=   '</tr>
                                 </thead>';
        //查找最新的固化數據
        $search = RechargeStatistics::find()->where($where)->asArray()->all();
        if(!empty($search)){
            foreach ($search as $key => $value){
                $search[$key]['recharge'] = unserialize($value['recharge']);
            }
        }
        //html語句填充數據
        if(empty($search)){
        }else{
            foreach ($search as $k) {
                $excel_content  .= '<td>'.$k['company_id'].'</td>';
                $excel_content  .= '<td>'.$k['company_name'].'</td>';
                foreach ($rechargelist1 as $v=>$t){
                    $price = 0;
                    foreach ($k['recharge'] as $q=>$w){
                        if($w['recharge_id'] == $v){
                            $price = $w['price'];
                            break;
                        }
                    }
                    $excel_content  .= '<td>'.$price.'</td>';
                }
                $excel_content  .= '<td>'.$k['total'].'</td>';
                $excel_content  .= '<td>'.$k['consume'].'</td>';
                $excel_content  .= '<td>'.($k['total']-$k['consume']).'</td></tr>';
            }
        }
        $excel_content  .=  '</table>';
        echo $excel_content;
        die;
}

2.結果

到這裏基本就完成全部的任務了！
