Bug description:last chance to work with __call by reference died after
removing call-time-&
Description:
------------
As of PHP 5.4 our content management system became not working without
possibility to get it to life. Beacause of a bug of removing call-time
passing
by reference.
Explanation:
We have magical loading of «methods» in class as __call() - processed
launches:
__call:
1. seeking existing of function If it exists â then function launches
and everything is ok.
2. If there is no such function â it's been loaded from _functions/
directory:
So we have auto-loading of functions.
BUT:
Because of __call don't support (why???) references we could call our
methods like this:
$sm->test( &data );
and in test-function we were be able to work BY REFERENCE. In php53 there
was
deprecations â ok, we were turning them off. BUT as of php54 we
completely can't
load virtual function with passing reference nohow... at all.
Ok, we can to preload function if it doesn't exist. But we already can't
work by
reference. So... in case of dealing with realy big array we will have to
push
that into the function and COPY back to the original. This is a huge
CPU/memory
consuming way.
Sooo... If there is no way to pass to the __call Maybe dear authors will
revert
support (even with peprecation-errors) for future times exactly untill
__call
could deal with reference (if that will never start working with reference
â
maybe there should be way to work with __call at least by passing reference
in
call-time maner?)
I belive that __call and its ability of working by reference is a criticaly
important (maybe not so usual happen) but important thing to leave in PHP
still
working
Test script:
---------------
<?php
class sm{
function __call($n, $val){
if( !function_exists($n) )
include $n;
return call_user_func($n, $val); // call_user_func can
not use
reference either. But everything works when we pass reference call-time.
}
}
$sm = new sm();
$data = array('prop'=>1);
function test( &$d ){
$d['prop'] = 2;
}
$sm->test( &$data ); // PHP 5.2, 5.3(deprecated) $data['prop'] === 2
//!!!!!!!!! as of PHP54 this techinique will stop working and working by
reference to __call will not be working in all PHP-version as of 54.
$sm->test( &$data ); // PHP 5.4(removed) fail
?>
