What? sorry i really don't understand what you are talking about.. i am
trying to set the value of $mmm... thats why it currently has no
value... the behaviour of $$var should be $(value of $var) which is
'mmm' so the variable variable should resolve to $('mmm') not the value
of $mmm as that would be rediculous, talk about recurssion!!!
Anyway that is beside the point - i know i am correct because the whole
thing works when not in the confines of a function. All this information
can be found on the link that i posted.
$v = 'albert';
$var = 'mmm';
$$var = &$v;
This works fine...! so why putting it within a function does anything
change... unless you can't safely globalize a variable variable... (ie.
global $$var - but this works for other values) or variable variabling a
reference changes the behaviour of the variable variable????
i couldn't find any information about this problem / feature in the
references section or the variable variables section so where else can
i look, i even searched the whole site for anything along the same
lines??? And i reject the insinuation that i didn't check it in the
first place...
It also works if i remove the referencing to $v and just copy $v's
value:
$v = 'albert';
function test($var){
global $$var, $v;
$$var = $v; // <--- no referencing!!
}
test('mmm');
var_dump($mmm);
exit;
The above code works fine and $mmm is set to the correct value "albert"
outside of the functions reach.
So what is going on, please can you give me a better explaination? this
problem causes me no hinderance what-so-ever as i can code around it to
my hearts content but anything that i see as a flaw in logic leaves me
to worry about the reliability of a language. You may be a volenteer
and you probably have to wade through a lot of requests, but if a jobs
worth doing its worth doing well and i really think that you haven't
fully looked into what i "took the time" to write.
Thank you

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
$$var = &$v;
resolves to
$(value of $mmm) = &$v;
Since $mmm contains no value nothing happens.

In order for the link i posted to work it needs to include the "08" on
the end... altho it has been wrapped by your parser function, just
making sure - it maybe quite obvious but i really want this problem
looked into / commented on and not cast aside.

Description:
------------
When a variable variable is globalized into a function and then its
value is set to a reference of another variable, the variable
variable's value does not extend past that of the function.
Reproduce code:
---------------
$v = 'albert';
function test($var){
global $$var, $v;
$$var = &$v;
}
test('mmm');
var_dump($mmm);
exit;
// for further examples follow the link below:
//
http://www.ourproperty.co.uk/test/index.php?code=0&allowin=SECurePHRase808
Expected result:
----------------
string(6) "albert"
Actual result:
--------------
NULL
