从PHP中的SQL查询中删除文本结果

Question

我有这段代码：

$result = mysqli_query($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”数字，而不是“数组（[SUM（angsuran）] =＆gt;）”。

我该怎么做？

Answer 1

在您的查询中添加别名，例如

Resource.resx: (used shift+enter to add line break)

LongText:   
Long text needed to show/

With to line in the browser

View.cshtml: 
(just adds one space -> Long text needed to show/ With to line in the
browser)

@MyResources.Resource.LongText

Answer 2

我有两种方式

使用array 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
