how to call a function only in specific pages and exclude it from other pages

if you know which page id , for example , you can change your page.php

if ( get_the_ID() == '99' ) {
       my_specific_page_99_calls();
}

and then on functions.php

my_specific_page_99_calls(
     require_once(GABFIRE_FUNCTIONS_PATH. '/review-options.php');
     require_once(GABFIRE_FUNCTIONS_PATH . '/custom.php');
     require_once(GABFIRE_FUNCTIONS_PATH . '/shortcodes.php');
     require_once(GABFIRE_FUNCTIONS_PATH . '/post-types.php');
)

i’m sure there’s other options, but this will get you there.

to exclude from specific pages

if ( !in_category('cake') {
       my_specific_page_99_calls();
}
