Laravel filter(remove) null and empty array values from Request

Question

In my laravel request I am sending data as given below..

{
    "user_id":13,
    "location":null,
    "about":"This Is About the user",
    "avatar":[],
    "users":[
        {
            "user_name":"John",
            "age":"30",
        },
        {
            "user_name":"Jessy",
            "age":"30",
        }
    ]
}

All the request keys can be null or hold a value (an array or string) so I want to filter only keys which has value.

Expected Output:

{
    "user_id":13,
    "about":"This Is About the user",
    "users":[
        {
            "user_name":"John",
            "age":"30",
        },
        {
            "user_name":"Jessy",
            "age":"30",
        }
    ]
}

I have tried

$userRequestData = $request->only([
    'location','about','avatar','users'
]);

$Data = array_filter($userRequestData, 'strlen');

But it only works if the request has only string values...

How can I filter it even if it's a string or an array?

do you also want to filter the nested key-values like user_name key inside users? — Mohsen Nazari

If you don't pass the 'strlen' parameter to array_filter, it will filter out falsyvalues:

$request = [
    "user_id"=>13,
    "location"=>null,
    "about"=>"This Is About the user",
    "avatar"=>[],
    "users"=>[
        [
            "user_name"=>"John",
            "age"=>"30",
        ],
         [
            "user_name"=>"Jessy",
            "age"=>"30",
        ]
    ]
];

will become

$request = [
    "user_id"=>13,
    "about"=>"This Is About the user",
    "users"=>[
        [
            "user_name"=>"John",
            "age"=>"30",
        ],
         [
            "user_name"=>"Jessy",
            "age"=>"30",
        ]
    ]
];

Documentation for array_filter

In your example you could do this:

$userRequestData = array_filter($userRequestData);

You can use collection to filter null values

collect(request()->all())->filter()

or

$result = collect(request()->all())->filter(function ($request){
    return is_string($request)&&!empty($request)||is_array($request)&&count($request);

});

To get array

$result = collect(request()->all())->filter()->toArray()

or for custom

$result = collect(request()->all())->filter(function ($request){
    return is_string($request)&&!empty($request)||is_array($request)&&count($request);
        
})->toArray();
