php使用指定编码导出mysql数据到csv文件的方法
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";
}
?>
