Mad Libs タイプの課題に取り組んでいます。教授がストーリーで使用させているカエルの名前をヒーローネームで指定しようとしていますが、何らかの理由で、カエルの名前を変更する if ステートメントが機能しません。

ヒーロー名の名前を入力しようとするたびに (「あなたの名前」を尋ねると、常にデフォルトで Taylor になり、Henry がカエルの名前になります。この if-else ステートメントを正しく機能させて名前を Henry にするにはどうすればよいですか?ヒーローネームにテイラーかジェイミーが入力された場合のみ？

比較ではなく割り当てを行っています。に変更if($heroname="Taylor"):しますif($heroname=="Taylor"):(つまり、=である必要があります==)。

(注: 最初の条件だけでなく、 4 つの条件すべてで修正する必要があります。)

比較演算子 (==/===) ではなく代入演算子 (=) を使用しています

if($heroname="Taylor"):
$frogname="Henry";
elseif($heroname="taylor"):
$frogname="Henry";
elseif($heroname="Jamie"):
$frogname="Henry";
elseif($heroname="jamie"):
$frogname="Henry";
else: $frogname="Matthew";
endif;

に

if($heroname == "Taylor")
    $frogname = "Henry";
elseif($heroname == "taylor")
    $frogname = "Henry";
elseif($heroname == "Jamie")
    $frogname = "Henry";
elseif($heroname == "jamie")
    $frogname = "Henry";
else
    $frogname = "Matthew";

さらに良い：

switch($heroname){
    case 'Taylor':
    case 'taylor':
    case 'Jamie':
    case 'jamie':
        $frogname = 'Henry';
        break;
    default:
        $frogname = 'Matthew';
}

ここに実用的なものがあります。このようにしてみてください：

if (in_array(strtolower($heroname), array("taylor", "jamie"))) $frogname="Henry";
else $frogname=="Matthew";
