如何在PHP中反转多级数组

如何简单地反转此数组，使最后一条记录显示在第一位，而其他记录将按相反顺序逐个排列

我尝试了

$MyArray=array\u reverse（$MyArray，true）

但它只移动顶部的“状态”：“ok”，而

产品

数组中的所有其他记录保持不变。那么，我如何仅反转

产品

阵列的记录，而不反转

“状态”：“ok”

您还可以使用array\u merge

    $json = '
    {
        "product": [{
            "IDs": ["00000087102110"],
            "Brand": "SONY",
            "Rank": 1
        }, {
            "IDs": ["00000087102120"],
            "Brand": "SAMSUNG",
            "Rank": 1
        }, {
            "GPI14s": ["00000087102150"],
            "Brand": "HCL",
            "Rank": 1
        }, {
            "GPI14s": ["00000087102110"],
            "Brand": "LG",
            "Rank": 1
        }, {
            "GPI14s": ["00000087102120"],
            "Brand": "LENOVO",
            "Rank": 1
        }, {
            "GPI14s": ["00000087102150"],
            "Brand": "HP",
            "Rank": 1
        }],
        "status": "ok"
    }';

    $decoded = json_decode($json,true);
    $reverse['product'] = array_reverse($decoded['product']);
    unset($decoded['product']);
    $reverse = array_merge($reverse,$decoded);

    echo json_encode($reverse,JSON_PRETTY_PRINT);

和输出：

{
"product": [
    {
        "GPI14s": [
            "00000087102150"
        ],
        "Brand": "HP",
        "Rank": 1
    },
    {
        "GPI14s": [
            "00000087102120"
        ],
        "Brand": "LENOVO",
        "Rank": 1
    },
    {
        "GPI14s": [
            "00000087102110"
        ],
        "Brand": "LG",
        "Rank": 1
    },
    {
        "GPI14s": [
            "00000087102150"
        ],
        "Brand": "HCL",
        "Rank": 1
    },
    {
        "IDs": [
            "00000087102120"
        ],
        "Brand": "SAMSUNG",
        "Rank": 1
    },
    {
        "IDs": [
            "00000087102110"
        ],
        "Brand": "SONY",
        "Rank": 1
    }
],
"status": "ok"
}

$MyArray[“product”]=array_reverse（$MyArray[“product”]，true）；你试过这个吗？顺便说一句，在显示时，你也可以反向解析数组，而不是反向读取。如果点是以反向顺序仅循环，则只从最后一个循环到第一个循环，而不是更改结构。在应用

数组反向（）

之前，你是否执行了

json\u decode（）

这项操作？@RK Ahir，当您

print\u r（）

解码的数组时，您会看到它在顶层有两个条目，“product”和“status”

array\u reverse（）
{
"product": [
    {
        "GPI14s": [
            "00000087102150"
        ],
        "Brand": "HP",
        "Rank": 1
    },
    {
        "GPI14s": [
            "00000087102120"
        ],
        "Brand": "LENOVO",
        "Rank": 1
    },
    {
        "GPI14s": [
            "00000087102110"
        ],
        "Brand": "LG",
        "Rank": 1
    },
    {
        "GPI14s": [
            "00000087102150"
        ],
        "Brand": "HCL",
        "Rank": 1
    },
    {
        "IDs": [
            "00000087102120"
        ],
        "Brand": "SAMSUNG",
        "Rank": 1
    },
    {
        "IDs": [
            "00000087102110"
        ],
        "Brand": "SONY",
        "Rank": 1
    }
],
"status": "ok"
}
