Hello!
How can I know if a user function exists? Must I use zend_hash_find()?
How?

Thank you,

Yup, zend_hash_find on the function_table hash (check how
function_exists (Zend/zend_builtin_functions.c) is implemented).

And... how could I know which PHP file is being executed and which line
I'm on? Is there any simple way of getting it?

Take a look at zend_error() in zend.c, where it says "Obtain relevant
filename and lineno".
