How to export a csv file and use a table to export an excel file using thinkPHP

This article mainly introduces thinkPHP's method of exporting csv files and outputting excel files using tables. it involves thinkPHP's operations on tables and Excel files, for more information about how to export a csv file from thinkPHP and use a table to output an excel file, see the following example. We will share this with you for your reference. The details are as follows:

1. thinkphp exports csv files

The exported csv file may have just a few lines of code. today I have a problem for a long time, that is, some html code is generated after export. This should not be because the view is empty, the controller does not end with $ this-> display (). at last, we carefully read think_page_trace and suddenly realized that it is the page tracking log, which is output by default. Finally, add an exit after the method. the following code is used:

1. IndexController. class. php

<? Phpnamespace Home \ Controller; use Think \ Controller; class IndexController extends Controller {public function index () {$ hotel = M ('keyword')-> field ('pagename, page ') -> select (); $ str = "keyword, name \ n"; $ str = iconv ('utf-8', 'gb2312 ', $ str ); $ result = mysql_query ("select PageName, Page from cmd_keywords"); while ($ row = mysql_fetch_array ($ result) {$ PageName = iconv ('utf-8 ', 'gb2312', $ row ['pagename']); $ Page = iconv ('utf-8', 'gb2312 ', $ row ['Page']); $ str. = $ PageName. ",". $ Page. "\ n" ;}$ fileName = date('Ymd').'.csv '; $ model = D ('keyword'); $ model-> export_csv ($ fileName, $ str); exit ;}}

2. KeywordsModel. class. php

<?php namespace Home\Model;use Think\Model;class KeywordsModel extends Model{ public function export_csv($filename, $data){  header("Content-type:text/csv");   header("Content-Disposition:attachment;filename=".$filename);   header('Cache-Control:must-revalidate,post-check=0,pre-check=0');   header('Expires:0');   header('Pragma:public');  echo $data;   }}

The secret lies in exit in the last sentence of IndexController. class. php code. if you do not write this sentence, the output excel file contains the html source code, as shown below:

2. output excel in a table

The following code is used: purchase_prospects.php.

<? Phprequire ('page _ header. php '); $ site_id = getIfSet ($ _ GET, 'site _ id', 0); $ customer_type = getIfSet ($ _ GET, 'Customer _ type', 0 ); $ DB = Database: connect ($ site_id); if ($ site_id> 0 & $ customer_type> 0) {$ SQL = ''; $ out = ''; $ short_name_array = SiteSettings: $ SITE_SHORT_NAME; $ short_name = $ short_name_array [$ site_id]; switch ($ customer_type) {case '1': {$ SQL = "SELECT email, CONCAT (UCASE (LEFT (firstname, 1), SUBSTRING (firstname, 2) AS firstname, CONCAT (UCASE (LEFT (lastname, 1), SUBSTRING (lastname, (2) AS lastname FROM customers WHERE site_id = $ site_id AND email not regexp '. + (avanquest) | (planetart) | (novadevelop) | (qatest ). + 'AND email IN (SELECT. email FROM customers a inner join orders B ON. id = B.
