Comment (by henry.wright):

 Taken from the manual entry for `call_user_func_array()`

 > Before PHP 5.4, referenced variables in param_arr are passed to the
 function by reference, regardless of whether the function expects the
 respective parameter to be passed by reference. This form of call-time
 pass by reference does not emit a deprecation notice, but it is
 nonetheless deprecated, and has been removed in PHP 5.4
