在会话中存储数组

So I'm trying to store an array in a session, but instead of making it an array it just counts everything up all the time! I just want the value that is done in the session, so I can check if the number isn't done already! There meight be a smarter way to it, but this will do for now!

public function nextNumber($list) {

    $i = rand(1, count($list)-1);

    echo $list[$i];

    if (!in_array($list[$i], Session::get('savedlist'))) {
        Session::put('savedlist', Session::get('savedlist') + $list[$i]);

        var_dump(Session::get('savedlist'));

        return $list[$i];
    }

}

And this is my put function

public static function put($name, $value) {
     return $_SESSION[$name] = $value;
}

public static function get($name) {
    return $_SESSION[$name];
}

I don't know if I undersood your question correctly, however I think that the put function needs to be updated:

public static function put($name, $value) {
    if(empty($_SESSION[$name])){
       // create a new array with the given name
       $_SESSION[$name] = array($value);
    } else {
       // add a new item at the end of the array
       $_SESSION[$name][] = $value;
    }
}

adding the two square brackets after [$name] will insert $value as a new item at the end of $_SESSION[$name]. Otherwise it will be only a variable, not an array.

Then change the nextNumber($list) function as follows

change this line:

Session::put('savedlist', Session::get('savedlist') + $list[$i]);

with

Session::put('savedlist', $list[$i]);

So the new value will be put at the end of the savedlist array.

I can't fully understand what you want to do, but since you accepted @lastYorsh answer, I'll assume you want something like his.

If we assume that Session::get('savedlist') can return an array then you can't add a number to an array with the + sign. Session::get('savedlist') + $list[$i]

I think @lastYorsh implementation should also have an if statement for the case that second argument is an array is_array().

Furthermore.

Warning: Cannot use a scalar value as an array

Try this

$_SESSION[$name] = []; // array();
$_SESSION[$name][] = $value;

But then

if (!in_array($list[$i], Session::get('savedlist'))) {

You can't use the in_array in associative arrays.

That lead us to the conclusion that @lastYorsh answer isn't what you want. Leave your Session implementations as it is and change this

if (!in_array($list[$i], Session::get('savedlist'))) {
        $savedlist = Session::get('savedlist');
        array_push($savedlist, $list[$i]);
        Session::put('savedlist', $savedlist);
