PHP If or not woking in textbox

Hi!

So I have an if function and I'm using or in it. It's not working. When I entere texts in the textbox it doesn't say it's correct if it's correct.

It's a quiz sample file.

When I run it it only say correct if I wrote the first answer in the textbox and it doesn't say correct if I write the second answer.

   <?PHP
    $verbs = array(
        'Aller',
        
        
    );
    $verb = array_rand($verbs);
    $averb =  $verbs[$verb];
    $sujets = array(
        'Je',
        'Tu',
       
        
    );
    $sujet = array_rand($sujets);
    $asujet =  $sujets[$sujet];

    $negposs = array (
        
        'Positive',
        );
        $negpos = array_rand($negposs);
    $anegpos =  $negposs[$negpos];
        echo "$asujet + $averb => Sentence: $anegpos";
        echo '<form action="quiz.php" method="POST">';
        echo "<p>Write everything in lowercase</p>";
        echo "<input type='text' name='ans' requird>";
    echo '<p><input type="submit" value="Refresh Page"</p>';
    echo "</form>";
        
    //Check Answer
    $ans = $_POST["ans"];
    echo "<p>$ans</p>";
    if (isset($_POST["ans"])){
        if ($averb == "Aller"){
            if ($anegpos == "Positive"){
                if ($asujet == "Je"){
                    if ($ans == "je suis allé" || $ans == "je suis allée"){
                        echo "Correct!";
                        echo "<p>$averb</p><p>$asujet</p>";
                        
                    } else {
                        echo "Wrong";
                    }
                } elseif ($asujet == "Tu"){
                     if ($ans == "tu es allé" || $ans == "tu es allée"){
                        echo "Correct!";
                        
                    } else {
                        echo "Wrong";
                    }
                } elseif ($asujet == "Il/Elle/On"){
                     if ($ans == "il a allé" || $ans == "elle a allée" || $ans=="on a allé"){
                        echo "Correct!";
                        
                    } else {
                        echo "Wrong";
                    }
                } elseif ($asujet == "Nous"){
                     if ($ans == "nous sommes allés" || $ans == "nous sommes allées"){
                        echo "Correct!";
                        
                    } else {
                        echo "Wrong";
                    }
                } elseif ($asujet == "Vous"){
                     if ($ans == "vous êtes allés" || $ans == "vous êtes allées"){
                        echo "Correct!";
                        
                    } else {
                        echo "Wrong";
                    }
                } elseif ($asujet == "Ils/Elles"){
                     if ($ans == "ils sont allés" || $ans == "elles sont allées"){
                        echo "Correct!";
                        
                    } else {
                        echo "Wrong";
                    }
                }
            }
        }
    }
    ?>
