PHP合并条件数组 [英] PHP merge arrays with a condition

问题描述

我有2个数组.我想将它们合并为1个数组，但要有条件.如果Ref和Id相等，则合并

I have 2 arrays. I would like to merge them into 1 array but with a condition. If Ref and Id are equal then merge

 Array Number One
(
[0] => Array
    (
        [Id] => 60
        [Name] => Water Authority
    )

[1] => Array
    (
        [Id] => 63
        [Name] => Service Station 
    )

Array Number Two
 (
    [0] => Array
    (
        [Date] => 2017-10-12
        [Amount] => 130.00
        [Ref] => 60
        [Description] => Water Bill Oct
    )

[1] => Array
    (
        [Date] => 2017-10-10
        [Amount] => 130.00
        [Ref] => 63
        [Description] => Gas
    )

[2] => Array
    (
        [Date] => 2017-09-17
        [Amount] => 600.00
        [Ref] => 60
        [Description] => Water bill Sept
    )

我想将它们合并在一起，所以最终得到:

I would like to merge them with so I end up with:

    Merged Array
 (
    [0] => Array
    (
        [Date] => 2017-10-12
        [Amount] => 130.00
        [Ref] => 60
        [Description] => Water Bill Oct
        [Id] => 60
        [Name] => Water Authority
    )

[1] => Array
    (
        [Date] => 2017-10-10
        [Amount] => 130.00
        [Ref] => 63
        [Description] => Gas
        [Id] => 63
        [Name] => Service Station 
    )
   and so on...

我该怎么做?我尝试了array_merge，但我知道它还需要其他东西，只是不知道什么！

How would I do that? I tried array_merge but I know it needs something else, just don't know what!

推荐答案

假设第一个数组为$ array1，第二个数组为array2

Let assume first array be as $array1, second array be array2

$ result = [];

$result = [];

foreach ($array1 as $key1 => $value1) {
    foreach ($array2 as $key2 => $value2) {
        if ($value1['Id']==$value2['Ref']) {
            $result[]=$value2+$value1;
        }
    }
}

结果将与您预期的一样
