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;">
/*
- 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
*/
- 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";
}
?>
希望本文所述对大家的PHP程序设计有所帮助。
