FINALLY!! Need your advices (Dice Challenge)

I’m so happy, really took me two days to make this :D, i know it’s too simple but im just a beginner in this and im really so happy i made this all by myself.

I want you guys to tell me if there’s another way (shorter and easy) to make this or maybe if you see mistakes or something that the code doesn’t really need

HTML/PHP:

<!DOCTYPE html>
<html>
    <head>
        <title>Your own do-while</title>
        <link type='text/css' rel='stylesheet' href='style.css'/>
    </head>
    <body>
    <p>Lets see how many times we need to trow a dice to get 6</p>
    <?php
        $trowcount = 0;
        do{
            $trow = rand(1,6);
            $trowcount++;
            if($trow){
                switch ($trow) {
                    case 1:
                        echo "<p class=dice>1</p>";
                        break;
                    case 2:
                        echo "<p class=dice>2</p>";
                        break;
                    case 3:
                        echo "<p class=dice>3</p>";
                        break;
                    case 4:
                        echo "<p class=dice>4</p>";
                        break;
                    case 5:
                        echo "<p class=dice>5</p>";
                        break;
                    case 6:
                        echo "<p class=dice>6</p>";
                        break;
                    default:
                        echo "<p>The dice flew away!!</p>";
                }
            }
        }while($trow < 6);
        $w1 = "";
        $w2 = "tries";
        
        if($trowcount == 1){
        $w1 = "just";
        $w2 = "try";
        };
        echo "<p>¡There you go! it took $w1 $trowcount $w2 to get 6 </p>";
    ?>
    </body>
</html>
