将原始超链接转换为img

       <div class="listing_element info_pro">
        <p class="pro_title">Country</p>
        <div class="sub_text text_small pro_text"><?php echo countryFlag($user['country']); ?></div>

    </div>

with the above code I was trying to add Country flag into a profile page, I have succeeded somehow but the code shows the path of the flag. I want to have it shown as an image.

use <img> tag with src

<div class="sub_text text_small pro_text"><img src="<?php echo countryFlag($user['country']); ?>" height="50" width="50"></div>
