Are Php User Defined Functions Defined/redefined Every Time A Page Loads?

Are php user defined functions defined/redefined every time a page loads?


I have a functions page and function_exist() tells me the function is redefined every time I load a page.


Is this correct, is this the nature of the beast that the functions will be redefined each time the function.inc file is used?


When they(books) say remember, are they taking about a page that uses the function.inc file 2,3,4 5 times?
