让Apache / PHP根据文件扩展名设置MIME类型，以将文件作为PHP执行

Question

I have an Apache/PHP based server on which I've made Apache execute js , html and css files as PHP via the following line in /etc/mime.types :

application/x-httpd-php phtml pht php js html css

We did this because even though any files we save as .html / .js / .css are almost entirely non-PHP, we need to do a bit of templating in them (for example, changing the domain of some URLs depending upon whether we are on the live or testing server).

The trouble is, this method of making Apache treat those files as PHP causes them to be returned with the wrong MIME type, which at the very least breaks css files in Chromium and probably has nasty effects in other browsers too.

Is there a way I can tell Apache to execute these files as PHP but still output them with the correct MIME type for their file extension? I don't want to have to manually paste

<?php
  header("Content-type: text/css");
?>

at the top of all of our .css files.

Why not do the dynamic parts in the main document then, where you are dynamic anyway? Running all the resources through the PHP interpreter is such a waste.

For JavaScript:

<script>
domain = "<? echo $domain; ?>";  <----- dynamic bits here
</script>
<script src="xyz.js"></script>   <----- you can use them in xyz.js

For CSS:

<link rel="stylesheet" href="stylesheet.css">

<style type="text/css">
 /* insert dynamic CSS here, overriding parts from the static style sheet */

 .my_div { color: <? echo $color; ?> }

</style>

Answer 2

It seems worth me noting that the only reason I ever ended up needing to ask this question was the wrong-headed approach I'd taken to having .js and .css files executed by PHP.

Don't modify your mime.types file to achieve this. Instead, in your Apache config (or in a .htaccess file), use invocations like this:

<Files *.js>
    ForceType application/x-httpd-php
    Header set Content-Type "application/javascript"
</Files>
<Files *.css>
    ForceType application/x-httpd-php
    Header set Content-Type "text/css"
</Files>

You can do it in two ways:

1. Create a .htaccess file.

   Now inside this file, make all the PHP files to be read as either .js or .css . Ideally, you will be having files like: style.css.php , scripts.js.php and are executed by Apache but the user will be getting the URL as style.css , scripts.js , etc.

2. Using Mime types .

   As you already said, by using the following, you can make these execute in the PHP.

    application/x-httpd-php phtml pht php js html css 

   Or another way is this:

    <FilesMatch "^.*?css*?$"> SetHandler php5-script </FilesMatch>
