Sometimes we need to import the Excel table data to the mysql database. we can use PHP-ExcelReader, an open source project of PHP, to easily import Excel. In addition, exporting mysql data to Excel is the same as exporting CSV data from the previous article on this site. you only need to replace the comma delimiter with a tab character and modify the header information.

Download source code

This article follows this article: use PHP to import and export the data tables and html of the instance in the CSV file.

1. import XLS

PHP-ExcelReader is an open-source project mainly used to parse excel files. you can obtain the latest source code from http://sourceforge.net/projects/phpexcelreader. After downloading and decompressing the files, we mainly use the two files reader. php and oleread. inc in the excel folder.

Import the Xls file: Select the xls file> upload the xls file to the server> use PHP-ExcelReader to parse the excel file> import the file in batches.

Include_once ("excel/reader. php "); // introduce PHP-ExcelReader $ tmp = $ _ FILES ['file'] ['tmp _ name']; if (empty ($ tmp )) {echo 'select the Excel file to import! '; Exit;} $ save_path = "xls/"; $ file_name = $ save_path.date ('ymdhis '). ". xls "; // save path and name of the uploaded file if (copy ($ tmp, $ file_name) {$ xls = new Spreadsheet_Excel_Reader (); $ xls-> setOutputEncoding ('utf-8'); // Set the encoding $ xls-> read ($ file_name); // Parse the file for ($ I = 2; $ I <= $ xls-> sheets [0] ['numrows ']; $ I ++) {$ name = $ xls-> sheets [0] ['cells '] [$ I] [0]; $ sex = $ xls-> sheets [0] ['cells '] [$ I] [1]; $ age = $ xls-> sheets [0] ['cells'] [$ I] [2]; $ data_values. = "('$ name',' $ sex ',' $ age')," ;}$ data_values = substr ($ data_values, 0,-1 ); // remove the last comma $ query = mysql_query ("insert into student (name, sex, age) values $ data_values"); // insert data tables in batches if ($ query) {echo 'import successful! ';} Else {echo' import failed! ';}}

PHP-ExcelReader reads the uploaded excel file and returns an array containing all information about the table. you can obtain the required information cyclically.

2. export XLS

Export the XLS process: Read the student information table-> Create a tab-separated field information loop record-> set the header information-> export a file (download) to a local

$ Result = mysql_query ("select * from student"); $ str = "name \ t gender \ t age \ t \ n "; $ str = iconv ('utf-8', 'gb2312', $ str); while ($ row = mysql_fetch_array ($ result )) {$ name = iconv ('utf-8', 'gb2312', $ row ['name']); $ sex = iconv ('utf-8', 'gb2312 ', $ row ['sex']); $ str. = $ name. "\ t ". $ sex. "\ t ". $ row ['age']. "\ t \ n" ;}$ filename = date('Ymd').'.xls '; exportExcel ($ filename, $ str );

The exportExcel function is used to set header information.

Function exportExcel ($ filename, $ content) {header ("Cache-Control: must-revalidate, post-check = 0, pre-check = 0 "); header ("Content-Type: application/vnd. ms-execl "); header (" Content-Type: application/force-download "); header (" Content-Type: application/download "); header ("Content-Disposition: attachment; filename = ". $ filename); header ("Content-Transfer-Encoding: binary"); header ("Pragma: no-cache"); header ("Expires: 0 "); echo $ content ;}

In addition, on the import and export Excel, you can also use PHPExcel, this is very powerful, you can go to study, official website: http://www.codeplex.com/PHPExcel import and export have become, you can export the office2007 format, at the same time compatible with 2003
