Use PHP to import Excel files and export data as Excel files

When using PHP to import Excel files and export data into Excel files, sometimes you need to import the data in the Excel tables to the mysql database. we can use PHP's open-source project PHP-ExcelReader to easily import Excel files.

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]; $ dat A_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;}
