模板引擎：包含

Question

I'm creating my own template engine using PHP. The basic idea is that for each page (visible for users) there are unique template file with HTML extension. For example...

users-list.php => users-list.html

profile.php => profile.html

about-us.php => about-us.html

I just made comments available in template files (actually HTML). Comments are visible before processed so real client won't see them, but developer would. Syntax is {* foo *}, and that's made up using regex's. Now I need something like...

{include "header.html"}

I don't know how to write it using code, but, imho, I need something like...

1) Match all {include "xxx"},

2) From matches took string between " and ",

3) Load files content in strings and add to correct place.

Answer 1

something like

 preg_replace_callback(
     '~{include "(.+?)"}~', 
     function($m) { return file_get_contents($m[1]) }, 
     $str);
