<?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) .
