# calling functions/php-files

 * Hi,
    I wrote two new functions in template-functions-post.php concerning the 
   behavior of single pages.
 * I would like to put these functions into a new ‘pagesbehavior.php’ so that my
   functions aren’t deleted when an update overwrites the existing temmplate-functions-
   post.php.
 * My only problem is that I don’t know how wordpress knows which *.php-file it 
   has to call to retrieve the corresponding function. So, how does <?php wp_list_pages(”);?
   > for example know that it must call template-functions-post.php to get the function
   wp_list_pages? It doesn’t call every php-files in the include-folder, does it?
 * Grateful for any help.

 * I don’t understand the *entire* hierarchy of php scripts in WordPress, but I 
   do know that most of this is handled through wp-settings.php. Anyway, here’s 
   some options I can suggest:
 * 1. Place your custom functions in a plugin.
 * 2. Add a functions.php to your theme and drop your functions in there.
 * 3. Include your pagesbehavior.php at the very end of wp-config.php (after wp-
   settings.php is included).
