Recursively cycle every path of an array

Question

I have the following(json) object:

$obj = json_decode(\'{
    \"Group1\": {
        \"Blue\": {
            \"Round\": [
                \"Harold\",
                 


        

Answer 1

Try this

i have created sample recursive program which u can tune

$obj = json_decode('{"Group1": {
        "Blue": {
            "Round": [
                "Harold",
                "Arthur",
                "Tom"
            ]
        },
        "Green": {
            "Round": [
                "Harold"
            ],
            "Circle": [
                "Todd",
                "Mike"
            ]
        }
    },
    "Group2": {
        "Blue": {
            "Round": [
                "Peter"
            ]
        }
    }
}');


recursive($obj);

function recursive($obj){

    if(is_array($obj)){

        foreach ($obj as $k => $v) {
            echo $v." ";
        }

        return;
    }

    foreach ($obj as $key => $value) {
        echo $key. " =>";
        recursive($value);
    }

    echo "\n";

}

Following is sample output

Group1 =>Blue =>Round =>Harold Arthur Tom 
Green =>Round =>Harold Circle =>Todd Mike 
Group2 =>Blue =>Round =>Peter
