我的数据库 表//名称：帐户

2  | ac    | example  | 2X:D0:5X:5E:77:CX
3  | ad    | example  | 5X:Y0:GX:FE:27:G8

查询

$sql = pg_query("SELECT * FROM accounts where macaddress = '2X:D0:5X:5E:77:CX' ")
while( $row = pg_fetch_assoc($sql) )
echo "$row[id]";

结果：1​​2

我想要的结果是：1,2

我希望你能帮助我解决这个问题。 谢谢

首先将值放入数组中并加入它们。

$array = [];

$sql = pg_query("SELECT * FROM accounts where macaddress = '2X:D0:5X:5E:77:CX' ")
while( $row = pg_fetch_assoc($sql) )
$array[] = $row[id];

echo join(',', $array);
