本文实例讲述了php使用指定编码导出mysql数据到csv文件的方法。分享给大家供大家参考。具体实现方法如下:
- <?php
- /*
- * PHP code to export MySQL data to CSV
- *
- * Sends the result of a MySQL query as a CSV file for download
- * Easy to convert to UTF-8.
- */
- /*
- * establish database connection
- */
- $conn = mysql_connect('localhost', 'login', 'pass') or die(mysql_error());
- mysql_select_db('database_name', $conn) or die(mysql_error($conn));
- mysql_query("SET NAMES CP1252");
- /*
- * execute sql query
- */
- $query = sprintf('SELECT field1,field2 FROM table_name');
- $result = mysql_query($query, $conn) or die(mysql_error($conn));
- /*
- * send response headers to the browser
- * following headers instruct the browser to treat the data as a csv file called export.csv
- */
- header('Content-Type: text/csv; charset=cp1252');
- header('Content-Disposition: attachment;filename=output.csv');
- /*
- * output header row (if atleast one row exists)
- */
- $row = mysql_fetch_assoc($result);
- if ($row) {
- echocsv(array_keys($row));
- }
- /*
- * output data rows (if atleast one row exists)
- */
- while ($row) {
- echocsv($row);
- $row = mysql_fetch_assoc($result);
- }
- /*
- * echo the input array as csv data maintaining consistency with most CSV implementations
- * - uses double-quotes as enclosure when necessary
- * - uses double double-quotes to escape double-quotes
- * - uses CRLF as a line separator
- */
- function echocsv($fields)
- {
- $separator = '';
- foreach ($fields as $field) {
- if (preg_match('///r|//n|,|"/', $field)) {
- $field = '"' . str_replace('"', '""', $field) . '"';
- }
- echo $separator . $field;
- $separator = ',';
- }
- echo "/r/n";
- }
- ?>
