我想从选项标签创建一个条件，例如如果我选择绿色，它将显示 5 张图像，但使用 for/do while 标签显示它？

Question

<select name="operator">
    <option name="green">green</option>
    <option name="purple">purple</option>
    <option name="orange">Orange</option>
</select><p></p><br>
<button type = "submit">Check</button>


for ($i=0; $i<=5; $i++) {
    echo "<img src = ""
}
