php - JSON 解码嵌套数组 PHP 循环

Question

我知道 Stackoverflow 上到处都有类似的问题，但我没有找到针对我遇到的问题的任何帮助。

我有这个 JSON:

[{
"name": "Name0",
"services": [
    [{
        "Service": "Service00",
        "Description": "Desc00"
    }, {
        "Service": "Service01",
        "Description": "Desc01"
    }]
]
}, {
"name": "Name1",
"services": [
    [{
        "Service": "Service10",
        "Description": "Desc10"
    }]
]
}]

我循环遍历它:

$quoteJson = json_decode($quoteJson);

foreach($quoteJson as $mydata) {
    echo $mydata->name . "<br>";
        foreach($mydata->services as $key => $value)
            {
                echo $value[$key]->Service . "<br>";
                echo $value[$key]->Description . "<br>";
            }
 }  

我得到的结果是:

Name0
Service00
Desc00

Name1
Service10
Desc10

我无法循环访问服务元素来获取:

Name0
Service00
Desc00
Service01
Desc01

Name1
Service10
Desc10

出于某种原因，services 是数组中的数组。对您的代码做了一个小更改:

foreach($quoteJson as $mydata) {                                                                                                  
    echo $mydata->name . "<br>";                                                                                                          
    foreach($mydata->services[0] as $key => $value)                                                                                       
    {                                                                                                                                     
        echo $value->Service . "<br>";                                                                                                    
        echo $value->Description . "<br>";                                                                                            
    }                                                                                                                      
}

现在它返回了:

Name0
Service00
Desc00
Service01
Desc01
Name1
Service10
Desc10
