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
.
