Decode json nested PHP (laravel)

Question

Sorry if this is rookie standard. The nesting really confuses me. Code here:

$json= '[{ "all":
 "{"data":
 [ {"name": "Kofi", "age":13}, {"name": "Jay", "age":17} ]
}"
}]' ;

$decode = json_decode($json);
$names= $decode->all->data->name;

// I want to retrieve "Kofi" and "Jay"

foreach ($names as $name){
echo $name;
}

I want to retrieve Kofi, Jay I get the error: Trying to get property 'all' of non-object

You have an array of one object. That one object has one key, all whose value is a string of JSON data. You need to decode the outer array, then decode the value of the all key. — bishop

try with $decode[0]->all->data[0]->name; and $decode[0]->all->data[1]->name; — dparoli

I ran your json, it wasn't formatted properly. I have formatted it and this extra bit of code should do the job for you.

NOTE: The only difference was "all": "{"...."}" changed to "all": { .... }

    $json= '[
            {
                "all":
                    {
                        "data":
                                [ 
                                    { "name": "Kofi", "age":13}, 
                                    {"name": "Jay", "age":17} 
                                ]
                    }
            }
        ]';

    $decode = json_decode($json);

    foreach($decode[0]->all->data as $dec) {
        echo $dec->name. '<br/>';
    }
