Why incrementing in PHP Session not working

session_start();
if(!isset($_SESSION['wylosowana'])) {
    $_SESSION['wylosowana'] = rand(1,100);
}

if(isset($_POST['liczba'])) {
    if(!isset($_SESSION['proba'])) {
        $_SESSION['proba'] = 1;
    }

    if($_POST['liczba']<$_SESSION['wylosowana']) {
        $_SESSION['blad'] = "Wprowadzona liczba jest za mała";

        if(isset($_SESSION['proba'])) {
            $_SESSION['proba']=+1; 
        }

    } else if ($_POST['liczba']>$_SESSION['wylosowana']) {
        $_SESSION['blad'] =  "Wprowadzona liczba jest za duża";
        if(isset($_SESSION['proba'])) {
            $_SESSION['proba']=+1; 
        }
    } else {
        $_SESSION['zgadles']=true;
        $_SESSION['blad'] =  "Wygrałeś za ".$_SESSION['proba']." razem";
    }
}

$_SESSION['proba'] always is equal to 1. To be honest i dont know where is the problem. I tried few methods but it still not working. Please tell me where is the problem. Thanks.

Your code : $_SESSION['proba']=+1;

Use instead $_SESSION['proba'] += 1; or $_SESSION['proba'] = $_SESSION['proba'] + 1;
