Audit call time pass by reference usage
|Reported by:||wonderboymusic||Owned by:||ryan|
In PHP 4, it was necessary to use a reference to create a callback that points to the actual object, and not a copy of it. This is no longer the case.
Also, I found more instances of $var = &my_func();. I have not touched any instance of $var1 =&$var2;. All unit tests pass (minus Tests_Theme_WPTheme::test_wp_theme_uris_with_spaces which always fails).
