Code: Select all
if you have error_reporting set to "E_ALL | E_STRICT" in php.ini then you'll get this in Apache logs :
"PHP Strict Standards: var: Deprecated. Please use the public/private/protected modifiers."
it is not good practice to declare global variables without saying what scope it is.

is this done in order to stay compatible with php 4 ?
