That bit of the documentation could be made clearer. It should probably say something along the lines of "... the variables *will* be passed by reference ...".

[PHP] Call-time pass-by-reference ??
Hello, I am trying to start a small php ncurses app but the documenatation is not helping. What does the following mean: PHP Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of ncurses_getmaxyx().

However, future versions may not support this any longer. in /home/michael/gsmenu/gsmenu on line 10 Here is my code: #!/usr/local/bin/php $y=0; $x=0; $ncurses_session = ncurses_init(); $main = ncurses_newwin(0,0,0,0); ncurses_getmaxyx (&$main,$y,$x ); ncurses_border(1,1,1,1, 1,1,1,1); ncurses_wrefresh($main); ncurses_end(); ?> If I remove the "&" from main nothing happens at all, the php documentation says that the variables should be passed from reference.

Re: [PHP] call-time pass-by-reference feature really deprecated?
Thanks for the explanation.
Yes, let us drop call-time pass-by-reference!! I'm with you. ;-)

"pass-by-reference" has not been dropped, it is "Call-time
pass-by-reference" which is being deprecated.
so call-time pass-by-reference is giving parameters as reference to
functions, e.g.
function returnObjectToAccumulator(&$obj) {...}
If this feature is really dropped, how would you implement
ConnectionPools for DB-connections for instance, or any classes
managing a set of object and providing them by returning references?
many OOP design patterns (primarily adopted from java) would not be
possible anymore. I think this would be worth talking about.
Is there any plausible reason for that decision?
"Call-time pass-by-reference"
=
function doo($i_may_or_may_not_be_a_reference) {
$i_may_or_may_not_be_a_reference++;
}
$i = 1;
doo($i);
echo $i; // 1
doo(&$i);
echo $i; // 2
// here doo() is not defined to have parameters passed by reference. The
decision on whether to pass by reference is made at run-time, hence call-time
pass-by-reference. It is this behaviour which is being deprecated.
So in the newer versions of PHP if call-time pass-by-reference is disabled and
you wish to pass parameters by reference you'll have to define your functions
accordingly:
function doo(&$i_am_passed_by_reference) { ... }

I think the latter is better anyways, because the caller shouldn't know the

Re: [PHP] Call-time pass by reference has deprecated
ummm, not to be insensitive but that error told you everything you
want to know.
passing by reference at call time is putting an & in front of a
variable. if you want to make it work, either modify your script to
not need call time pass by reference (you can change the function
declaration to force a pass by reference) or you can simply (and I'm
just cutting and pasting here from your message):
If you would like to enable call-time pass-by-reference, you can set
allow_call_time_pass_reference to true in your INI file
by INI file it means the php.ini file. you can find where this file
is in phpinfo()

In the existing code things are passed by reference where the calls are
made. The places you see these warnings. This style is going out of
style, in favor of one where you define passing by reference in the
function definition.
What to do:
Change the function calls from:
function_whatever( &$var1, &$var2 );
to
function_whatever( $var1, $var2 );
and change the finction definitions from:
function function_whatever( $var1, $var2 ) {
to:
function function_whatever( &$var1, &$var2 ) {
For now, since these are just warnings you could just turn down error
reporting, or enable allow_call_time_pass_reference as shown in the
warning, but you should seriously consider fixing the problem by
changing the code. Someday soon PHP will no longer allow the old syntax
at all.
