前端之家收集整理的这篇文章主要介绍了php使用指定编码导出mysql数据到csv文件的方法前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

本文实例讲述了PHP使用指定编码导出MysqL数据到csv文件方法分享给大家供大家参考。具体实现方法如下:

PHP;"> /*

  • 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";
}
?>
