PHP 将MySQL数据导出csv

1.查询数据

// 假设得到的数据格式如下
$result = array(
array(
"orderid" = "1110111",
"shopid" = "202302323",
),
array(
"orderid" = "1110111",
"shopid" = "202302323",
)
);

2.组装数据

$string = "订单ID,店铺ID\n";
foreach($result as $key => $value) {
$string .= $value['orderid'] . ',' . "\t"  . $value['shopid'] . "\t\n";
}

3. 改变编码格式

$string =iconv('utf-8', 'gb2312', $string);

4. 导出csv

$filename = date('Y-m-d').'.csv';
header("Content-type:text/csv");
header("Content-Disposition:attachment;filename=".$filename);
header('Cache-Control:must-revalidate,post-check=0,pre-check=0');
header('Expires:0');
header('Pragma:public');
echo $string;
