php json parsing objects

Question

I have a JSON file that I need to parse. I'm new to php and trying to figure out how to correctly parse the object. My question is: How do I parse the objects of an object that have different names

One object has the name Thresh the next object in the list has the name Aatrox the name of the top level object is data

This is what the JSON looks like. I can access the information if I know the name of the object $champion = $jfo->data->Thresh; but I don't want to have to type in all the names of the champions. Is there an easy way to obtain all the separate objects without knowing the names? Maybe regex?

"data": {
    "Thresh": {
        "id": 412,
        "key": "Thresh",
        "name": "Thresh",
        "title": "the Chain Warden",
        "image": {
            "full": "Thresh.png",
            "sprite": "champion3.png",
            "group": "champion",
            "x": 336,
            "y": 0,
            "w": 48,
            "h": 48
        },

 "Aatrox": {
        "id": 266,
        "key": "Aatrox",
        "name": "Aatrox",
        "title": "the Darkin Blade",
        "image": {
            "full": "Aatrox.png",
            "sprite": "champion0.png",
            "group": "champion",
            "x": 0,
            "y": 0,
            "w": 48,
            "h": 48
        },

You really should consider renaming your objects to something generic like "person" or "champion" instead of "Thresh" and "Aatrox". After all, those names are already in the objects. — unfairhistogram

the problem is that it comes to us like that. the names are predefined @felipsmartins i'll try to re-word it so that it makes more sense. — k3vy w3vy

no, you don't use regexes on the json. that's pointless. json_decode() to a native php data structure and then use normal array/object search methods on that. — Marc B

If you want to go through each champion, I'd recommend using a foreach loop in PHP. You can use it as such:

foreach($json->data as $champion)
{
    // Do something
}

You probably want to make it as $champion => $data - but, in this case, it doesn't really matter since in your example, `$champion['key'] achieves the same thing
