在PHP中从SQL查询中删除文本结果

我有以下代码：

$result = mysqli_query($conn, "SELECT SUM(angsuran) FROM `laporan` WHERE id_mustahik=".$detail_campaigner->id_mustahik."");
$row = mysqli_fetch_assoc($result);
print_r($row);

当我运行此代码时，结果是：

Array ( [SUM(angsuran)] => 30000 ) 

但我希望它只显示“30000”个数字，而不显示“Array（[SUM（angsuran）]=>）

我该怎么做呢？

我有两种方法

使用数组php

$result = mysqli_query($conn, "SELECT SUM(angsuran) FROM `laporan` WHERE id_mustahik=".$detail_campaigner->id_mustahik."");
$row = mysqli_fetch_assoc($result);
echo $row["SUM(angsuran)"]; // out 30000 

修改sql

$result = mysqli_query($conn, "SELECT SUM(angsuran) as sum FROM `laporan` WHERE id_mustahik=".$detail_campaigner->id_mustahik."");
$row = mysqli_fetch_assoc($result);
echo $row["sum"]; // out 30000 

---

在查询中添加别名，如

$result = mysqli_query($conn, "SELECT SUM(angsuran) as sumtotal FROM `laporan` WHERE id_mustahik=".$detail_campaigner->id_mustahik."");
$row = mysqli_fetch_assoc($result);
echo $row['sumtotal']; //outputs 30000

---

$row[“SUM（angsuran）”]

可能就可以了。感谢它的工作，它很简单：）使用别名更干净：

SUM（angsuran）作为SUM

然后

$row['SUM']
