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).
