PHP will load the entire file and consume memory. It will also check the sintax of the entire file. If your file grows to much it would affect the speed of showing your pages and if it is very big, you could find the limit of memory of PHP (8Mb by default).
The Zend engine makes an "on the fly" compilation before executing the functions (see Zend engine in the manual) so it consumes time. My recomendation should be to have a set of a few files with the functions grouped by category or by frecuency of use. Another inconvenient is that if you make a change in one function and by mistake have a syntax error, all the scripts that use that included file will crash until you fix it. I think it's not a nice solution :( Sorry, Gabriel.
