header("Content-Type: application/vnd.ms-excel; charset=GB2312");
header("Content-Disposition: attachment; filename=CSV data.csv ");

$rs = array(
 array('aa', "I'm li lei", '"boy"', '￥122,300.00'),
 array('cc', 'I'm han mei', '"gile"', '￥122,500.00'),
);
$str = '';
foreach ($rs as $row) {
 $str_arr = array();
 foreach ($row as $column) {
 $str_arr[] = '"' . str_replace('"', '""', $column) . '"';
 }
 $str.=implode(',', $str_arr) .PHP_EOL;
}
echo $str;
