如何在选项标签 select 下拉列表 1st 2nd 3rd 4th 5th 中添加上标。 1ST 我想要 S 大写字母，但我试过 s 将转换为小写

Question

我使用了下面的代码。 但是 1st --> 返回 1sT --> 我需要 1ST

<option value="1ST"
                <?php if (in_array("1ST", $_POST['pay_day'])) echo selected; ?>
                > 1&#x02E2;&#x1D40;   </option>
            <option value="2ND"
                <?php if (in_array("2ND", $_POST['pay_day'])) echo selected; ?>
                > 2&#x1D3A;&#x1D30;  </option>
            <option value="3RD"
                <?php if (in_array("3RD", $_POST['pay_day'])) echo selected; ?>
                > 3&#x1D3F;&#x1D30;  </option>
            <option value="4TH"
                <?php if (in_array("4TH", $_POST['pay_day'])) echo selected; ?>
                > 4&#x1D40;&#x1D34; </option>
            <option value="5TH"
                <?php if (in_array("5TH", $_POST['pay_day'])) echo selected; ?>
                > 5&#x1D40;&#x1D34; </option>
