Question

我在“主题”表中创建了要由学生选择的主题

表格“主题”

ID| SHORTNAME | SUBJECT_NAME 
1 | MT        | MATHEMATICS 
2 | ASC       | ADDITIONAL SCIENCE

此表中的列自动生成到表“ MID_YEAR_EXAMINATION”中

表“ MID_YEAR_EXAMINATION”

ID | STUDENT NAME | MT | ASC

学生在每个主题中获得的分数将插入表“ MID_YEAR_EXAMINATION”中

ID | STUDENT_NAME | MT | ASC
1  | ALEX         | 88 | 62
2  | ELLY         | 78 | 43

我的问题是我有两个数组 code2

$input1= array(
    "id" => $row['ID'],
    "name" => $row['STUDENT_NAME']
);

$sel_query3="Select * from SUBJECT  ORDER BY SUBJECT_NAME";
$result3 = @mysqli_query($con,$sel_query3);
while($row2 = @mysqli_fetch_assoc($result3)){   
    $MP = $row2['SHORTNAME'];
    $m = $row['SUBJECT_NAME']; //TO GET student's score 
    in each subject
            $input2 = array($MP => $m); 
    }
}
Echo  json_encode($input2);

如何通过编辑代码来修复该数组，如下所示：

从

[
    "id"   => "1",
    "name" => "ALEX",
    "MT"   => "88"
]
[
    "id"   => "1",
    "name" => "ALEX",
    "ASC"  => "62"
]

TO

[
    "id"   => "1",
    "name" => "ALEX",
    "MT"   => "88",
    "ASC"  => "62"
]

（“ MT”和“ ASC”合并为一个数组）

我需要你的帮助。谢谢！

使用PHP的array_merge()函数：https://www.php.net/manual/en/function.array-merge.php

如果将源数组分配给$ a和$ b，则只需$combined = array_merge( $a, $b );

如果$ b中$ a中相同名称的元素具有不同的值，则$ b中的值将获胜。

$a = [
  "id"   => "1",
  "name" => "ALEX",
  "MT"   => "88"
];
$b = [
    "id"   => "1",
    "name" => "ALEX",
    "ASC"  => "62"
];
print_r( array_merge( $a, $b ) );

输出：

Array
(
    [id] => 1
    [name] => ALEX
    [MT] => 88
    [ASC] => 62
)
