问题:

I have googled a lot but it seems that I am doing something wrong.

I want to do this:

<?php
include 'header.php';
include'CSS/main.css';
...
?>

However, my page prints the CSS code.

Note: I want to use PHP to include the CSS file, and not use I also do you want to rename my CSS file to a PHP file as some website mentioned.

Any clues?

Many thanks.

回答1:

You have to surround the CSS with a <style> tag:

<?php include 'header.php'; ?>
<style>
<?php include 'CSS/main.css'; ?>
</style>
...

PHP include works fine with .css ending too. In this way you can even use PHP in your CSS file. That can be really helpful to organize e.g. colors as variables.



回答2:

You are including the CSS code as text in your PHP page. Why not just link it in the traditional fashion?

<link rel="stylesheet" href="CSS/main.css" type="text/css">


回答3:

you can use:

<?php
$css = file_get_contents('CSS/main.css');
echo $css;
?>

and assuming that css file doesn't have it already, wrap the above in:

<style type="text/css">
...
</style>

To use "include" to include CSS, you have to tell PHP you're using CSS code. Add this to your header of your CSS file and make it main.php (or styles.css, or whatever):

header("Content-type: text/css; charset: UTF-8");

This might help with some user's connections, but it theoretically (read: I haven't tested it) adds processor overhead to your server and according to Steve Souder, because your computer can download multiple files at once, using include could be slower. If you have your CSS split into a dozen files, maybe it would be faster?

    <?php
    define('CSSPATH', 'template/css/'); //define css path

    $cssItem = 'style.css'; //css item to display

    ?>

<html>
<head>
 <title>Including css</title>
  <link rel="stylesheet" href="<?php echo (CSSPATH . "$cssItem"); ?>" type="text/css">
</head>
<body>
...
...
</body>
</html>

YOUR CSS ITEM IS INCLUDED

If you want to import a CSS file like that, just give the file itself a .php extension and import it anyway. It will work just fine :)



回答7:

You can also do the following:

  1. Create a php file in includes folder, name it bootstrap_css.php for example

  2. paste the css code files to file created above

     <?php 
  $minCss=' <link href="bootstrap/css/bootstrap.min.css" rel="stylesheet">';

 $business = '<link href="bootstrap/css/modern-business.css" rel="stylesheet">';

  echo $minCss;
  echo $business;
?>

  3. in the html header, include the css files as follows 

     <?php include_once 'includes/bootstrap_css.php'; ?>

This is an older post, however as the info is still relevant today an additional option may help others.

  • Define a constant for the file path per Stefan's answer. The definition can be placed at the top of the PHP page itself, or within an included/required external file such as config.php. (http://php.net/manual/en/function.include.php)

  • Echo the constant in PHP tags, then add the filename directly after. That's it!
    Works for other linked files such as JavaScript as well.

<?php
define('CSS_PATH', 'template/css/'); //define CSS path 
define('JS_PATH', 'template/js/'); //define JavaScript path 
?>
<!-- Doctype should be declared, even in PHP file -->
<!DOCTYPE html> 
<html>
<head>
<link rel="stylesheet" type="text/css" href="<?php echo CSS_PATH; ?>main.css">
<script type="text/javascript" src="<?php echo JS_PATH; ?>main.js"></script>
</head>
<body>
</body>
</html>


回答9:

You could do this

<?php include("Includes/styles.inc"); ?>

And then in this include file, have a link to the your css file(s).



回答10:

I don't know why you would need this but to do this, you could edit your css file:-

<style type="text/css">
body{
...;
...;
}
</style>

You have just added here and saved it as main.php. You can continue with main.css but it is better as .php since it does not remain a css file after you do that edit

Then edit your HTML file like this. NOTE: Make the include statement inside the tag

<html>
<head>
 <title>Sample</title>
 <?php inculde('css/main.css');>
</head>
<body>
...
...
</body>
</html>


回答11:

I solved a similar problem by enveloping all css instructions in a php echo and then saving it as a php file (ofcourse starting and ending the file with the php tags), and then included the php file. This was a necessity as a redirect followed (header ("somefilename.php")) and no html code is allowed before a redirect.



回答12:

The best way to do it is:

Step 1: Rename your main.css to main.php

Step 2: in your main.php add

<style> ... </style>

Step 3: include it as usual

<?php include 'main.php'; ?>

That is how i did it, and it works smoothly..



回答13:

Just put 

echo "<link rel='stylesheet' type='text/css' href='CSS/main.css'>";

inside the php code, then your style is incuded. Works 100%, I tried.



回答14:

_trace its directory, I guess

echo css('lib/datatables_rqs/jquery.dataTables.css');
