如何使用json_decode提取内部信息 [英] How to use json_decode to extract an inner information

问题描述

我是php新手.我需要json_decode/php的一些快速帮助.我需要在数组中获取g91的值，该怎么办?我想有一些递归值可以传递给json_decode ...

I am new to php. I need some quick help with json_decode/php. I need to get values of g91 in an array, how can I do this? I suppose there is some recursion value that we can pass to json_decode...

{
    "e": "none",
    "f": "test",
    "g": [
        {
            "g1": "text2",
            "g9": {
                "text3": {
                    "g91": 0,
                    "g92": [
                        "text5"
                    ]
                }
            }
        },
        {
            "g1": "text1",          
            "g9": {
                "text4": {
                    "g91": 0,
                    "g92": [
                        "text6",
                        "text7"
                    ]
                }
            }
        }
    ]
}

请注意，text3不是固定的.在下一条记录中，我有text4 ..

Please note that text3 is not fixed..in next record, I have text4..

谢谢！

推荐答案

将TRUE作为第二个参数传递给json_decode

Pass TRUE to json_decode as second parameter

$output = json_decode($input,TRUE);

比遍历数组.应该是这样的

Than traverse the arrays. It should be something like

$output['g'][0]['g9']['text3']['g91']

请参考 json_decode
