在PHP文件中使用CSS

Question

Well, everyone knows we can use HTML inside a PHP file. So can we also use CSS inside a PHP file and still call it like <link rel="stylesheet" type="text/css" href="mystyle.php" /> to pass PHP as a CSS file? I know we can generate CSS from PHP doing something like echo "<style> (…) </style>", but will the above work?

Answer 1

You can do this. In the mystyle.php, add in the first line:

header('Content-type: text/css');

Then do your code just like any PHP, using variables and such. Because of the header declaration, your php when opened by the browser will be parsed as a css file.

So you could do something like:

<?php 
header('Content-type: text/css');
/* ------------------------
    PHP Vars
------------------------ */
$color1 = "#fff";
$fontSize = "15px";

?>

.someSelector {
    color: <?=$color1;?>;
    font-size: <?=$fontSize;?>;
}
