使用php在json数组上放入逗号数字

Question

我想把逗号放在数字中 输出是以json数组

编码的

[{"total2":"7619627.0000"}]

我想更改此格式的数字

[{"total2":"7,619,627"}]

继承人的PHP代码

$sql2 = "SELECT SUM(NettoPrice) AS total2 FROM Sales WHERE OrderType = 8";
$result2 = $conn->query($sql2);

// output data of each row
while($row[] = $result2->fetch_assoc()) {

   $json = json_encode($row);


}
echo $json;
$conn->close();
?>

Answer 1

使用number_format（）;

$row[count($row)-1]['total2'] = number_format($row[count($row)-1]['total2']);
$json = json_encode($row);

Answer 2

使用MYSQL 5.5：

SELECT FORMAT(SUM(NettoPrice),0) AS total2;

SQL fiddle

使用PHP

number_format('7619627.0000',0);
