From manual page: http://www.php.net/function.function-exists#Description

The current description is : "Vérifie la liste des fonctions définies par l'utilisateur afin d'y trouver function_name.". This mean "Check the list of user-defined function,for function_name." And only user-defined.
The original (english) translation is : "Checks the list of defined functions, both built-in (internal) and user-defined, for function_name.".

So the french translation suggest that all built-in function are not checked (which is false).

The right french translation should be : "Vérifie la liste des fonctions définies par l'utilisateur ainsi que celles internes à php afin d'y trouver function_name".
