<para>
Referenced variables in <parameter>param_arr</parameter> 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 will most likely be removed in the next version of PHP.
Before PHP 5.4, referenced variables in <parameter>param_arr</parameter>
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 removied in PHP 5.4.
Furthermore, this does not apply to internal functions, for which
the function signature is honored. Passing by value when the function expects
a parameter by reference results in a warning and having
<function>call_user_func</function> return &false; (does not apply if the
passed value has a reference count = 1).
the function signature is honored. Passing by value when the function
expects a parameter by reference results in a warning and having
<function>call_user_func</function> return &false; (there is, however, an
exception for passed values with reference count = 1, such as in literals,
as these can be turned into references without ill effects — but also
without writes to that value having any effect —; do not rely
in this behavior, though, as the reference count is an implementation
detail and the soundness of this behavior is questionable).
