charger_fonction

This charger_fonction() (translation: load_function()) function is used to retrieve the name of an overloadable SPIP function. Whenever an internal function with a _dist() suffix is overloaded (by recreating it without that suffix), or whenever all of a file that contains such a function is overloaded, then the correct function to be run must be retrievable at the time that that function is to be executed.

This is what the charger_fonction() does. It returns the correct name of the function to be executed.

$ma_fonction = charger_fonction('my_function','directory');
$ma_fonction();

The searching principle

The function operates as follows:

• if the directory_my_function function has already been declared, then that function is returned,
• else directory_my_function_dist,
• else try to load a file called directory/my_function.php then
• return directory/my_function if it exists,
• else directory/my_function_dist,
• else return false.
