RE: [PHP] Passing by reference deprecated?

[Neil Kimber]

Pass by reference itself is not deprecated, just call-time
pass-by-reference.
I believe this means your calling line of code being prevented from
specifying that it should be invoked as pass-by-reference.

So,


function NormalPassByRefence(&$prmValue)
        {
        $prmValue ++;
        }

$numValue=1;
NormalPassByRefence($numValue);  // This will still work
// $numValue =2 at this point


function CallTimePassByRefence($prmValue)
        {
        $prmValue ++;
        }

$numValue=1;
CallTimePassByRefence(&$numValue);  // This will no longer work - it's been
deprecated
// $numValue =1 at this point

set_value(&$variable,$value)
   {
   $variable=value;
   }

"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 [runtime function name](). 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. However, future versions may not support this any longer. "

When did passing by reference get deprecated? The documentation at
<http://php.net/manual/en/language.references.pass.php> doesn't suggest
what to do instead--in fact, it uses an example like the syntax above.  So
my next question is: would using a return value or declaring a global be
the (only) other options?

TIA
