You can "style echo" with adding new HTML code.
您可以通过添加新的 HTML 代码来“样式回显”。
echo '<span class="city">' . $ip['cityName'] . '</span>';

Store your results in variables, and use them in your HTML and add the necessary styling.
将结果存储在变量中，并在 HTML 中使用它们并添加必要的样式。
$usercity = $ip['cityName'];
$usercountry = $ip['countryName'];
And in the HTML, you could do:
在 HTML 中，您可以执行以下操作：
<div id="userdetails">
<p> User's IP: <?php echo $usercity; ?> </p>
<p> Country: <?php echo $usercountry; ?> </p>
</div>
Now, you can simply add the styles for countryclass in your CSS, like so:
现在，您可以简单地country在 CSS 中为class添加样式，如下所示：
#userdetails {
/* styles go here */
}
Alternatively, you could also use this in your HTML:
或者，您也可以在 HTML 中使用它：
<p style="font-size:15px; font-color: green;"><?php echo $userip; ?> </p>
<p style="font-size:15px; font-color: green;"><?php echo $usercountry; ?> </p>
Hope this helps!
希望这可以帮助！

You cannot style a variable such as $ip['countryName']
您不能设置诸如 $ip['countryName'] 之类的变量的样式
You can only style elements like p,div, etc, or classes and ids.
您只能为 p、div 等元素或类和 id 设置样式。
If you want to style $ip['countryName'] there are several ways.
如果你想样式 $ip['countryName'] 有几种方法。
You can echo it within an element:
您可以在元素中回显它：
echo '<p id="style">'.$ip['countryName'].'</p>';
echo '<span id="style">'.$ip['countryName'].'</span>';
echo '<div id="style">'.$ip['countryName'].'</div>';
If you want to style both the variables the same style, then set a class like:
如果要将两个变量设置为相同的样式，请设置如下类：
echo '<p class="style">'.$ip['cityName'].'</p>';
echo '<p class="style">'.$ip['countryName'].'</p>';
You could also embed the variables within your actual html rather than echoing them out within the code.
您还可以将变量嵌入到实际的 html 中，而不是在代码中回显它们。
$city = $ip['cityName'];
$country = $ip['countryName'];
?>
<div class="style"><?php echo $city ?></div>
<div class="style"><?php echo $country?></div>
