required --- 輸入框不得為空

result.php 文件

<?php
    $name = $_POST["name"];
    $gender = $_POST["gender"];
    $adminis = $_POST["adminis"];

    if($gender == "male"){
        echo "嗨~ 住在".$adminis."的".$name."先生, 恭喜您抽中一台iPhone";
    } else {
        echo "嗨~ 住在".$adminis."的".$name."女士, 恭喜您抽中一台iPhone";
    }
?>

如果把 PHP 語法插入 HTML 文件內，就可以把 data 存進陣列裡用 foreach 叫出來

search.php 文件

<?php
    $adminis = array(
        "Taipei" => "台北市",
        "NewTaipei" => "新北市",
        "Taoyuan" => "桃園市",
        "Taichung" => "台中市",
        "Kaohsiung" => "高雄市",
        "Tainan" => "台南市"
    );
?>

            <label for="female">女</label><br><br>

            <label for="area">請選擇住址行政區 : </label>
            <select name="adminis" id="area">
                <?php foreach($adminis as $area_english => $area_chinese):?>
                        <option value="<?= $area_chinese?>"><?= $area_chinese?></option>
                <?php endforeach;?>

        </div>
        <br>
        <input type="submit" value="送出">
    </form>
</body>
</html>

在 HTML 中分開的 PHP，foreach(): 和 endforeach; 搭配使用。
<?php echo?> 可以寫成 <?= ?>

result.php 文件

<?php
    $name = $_POST["name"];
    $gender = $_POST["gender"];
    $area = $_POST["adminis"];
    
    if($gender == "male"){
        echo "嗨~ 住在".$area."的".$name."先生, 恭喜您抽中一台iPhone";
    } else {
        echo "嗨~ 住在".$area."的".$name."女士, 恭喜您抽中一台iPhone";
    }  
?>
