I believe pass-by-reference is now noted in function definitions ala:
function myFunc(&$myvar) {/* Function */}
whereas in PHP4, you could force pass-by-reference at runtime using:
myFunc(&$myvar);
This was depreciated because parameter definitions should be maintained in
the function definition, not in the function call. Whether a parameter is
pass-by-reference or value should be the same across all calls to maintain
consistency and reduce code (one ampersand instead of many).
