<?php
$Color = "red";
$Text = "This text is red";
echo '<div style="Color:'.$Color.'">'.$Text.'</div>';
?>
In php, you can use .to add variables together. In this case, the final output of the echo line is:
在php中，可以使用.将变量加在一起。在这种情况下，回声线的最终输出是：
<div style="Color:red">This text is red</div>
An example of this code in use can be seen here.

If applied color doesn't work even inline-style, so you can use !importantword, cos maybe all div colors come from css file and suppress inline-styles.
如果应用的颜色甚至内联样式都不起作用，那么您可以使用!importantword，cos 可能所有 div 颜色都来自 css 文件并抑制内联样式。
"<div style=\"color: white !important;\">$display</div>";

I know this is an old question but I write the answer in case someone has the same question and does not know where to look. I think you wanted to print links so this is why the previous methods didn't work.Inside your php file write the following:
我知道这是一个老问题，但我会写下答案，以防有人有同样的问题并且不知道去哪里找。我想你想打印链接，所以这就是之前的方法不起作用的原因。在你的 php 文件中写下以下内容：
echo "<html>
<head>
<style>
/* unvisited link */
a:link {
color: red;
}
/* visited link */
a:visited {
color: green;
}
/* mouse over link */
a:hover {
color: hotpink;
}
/* selected link */
a:active {
color: blue;
}
</style>
</head>
<body>
$variableYouWantToChangeColor
</body>
</html>";
You can change/remove parts of the css so it fits your needs.
您可以更改/删除部分 css 以使其适合您的需要。
