问题
What I'm trying to achieve is build a simple and lightweight theme engine, where anyone will be able to create his own template easily, I have managed to do this using PHP, and for example, if someone wants to input the logo, all they have to do is use: {logo} , and etc.
The template files extensions are '.inc'.. My problem is, i don't know how to allow users to still execute php code, using PHP (< ?php ?>) tags.
I have tried both adding this in my htaccess:
AddType application/x-httpd-php .inc
I know other template engines exist, such as smarty, but id rather go for something a lot more simpler.
回答1:
Not too many people will be happy to use a template engine which requires adding new web server handlers to use it.
Therefore it would be advisable to use a standard fully supported extension like .php instead of .inc or in case you are really willing to use .inc simply include the file with output buffering turned on and collect the output in a variable like this:
ob_start();
require "template.inc";
$content = ob_get_clean();
$content will hold whatever was inside template.inc so you can do whatever you want with it.
Not only that but if your template.inc file contains PHP variables they will be parsed too.

It has nothing to do with htaccess rules. You need to evaluate PHP content right after you finished interpreting your template tags. For instance:
eval( "?> $content_of_template <?php " );
