I tend to get errors such as:
Fatal error: Cannot redeclare get_raw_data_list() (previously declared in /var/www/codes/handlers/make_a_thread/get_raw_data_list.php:7) in /var/www/codes/handlers/make_a_thread/get_raw_data_list.php on line 19
how can I avoid the error? Is it possible to create a IF-clause to check whether a function is declared before declaring it?
