Same problem w/ CVS PHP 5.2 - Windows x86 VC6 (thread safe))  [10.02MB] - 2009-Jan-20 12:00:00

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

Do not do that..

I don't understand how is this bogus? I did look at the manual to make sure I used the variable variables and reference correctly.  Looking at the code give, if I pass string 'arr' to the function, then $$var == ${'arr'}. There is no ambiguity.  If I do a var_dump($$var) equivalent to var_dump(${'arr'}) inside the function right after global $$var, I get the defined global $arr array contents.  I didn't see any where in the manual at
http://www.php.net/manual/en/language.variables.variable.php
about not being able to use it or implement it inside a function since the examples didn't implement inside a function.

As for references, I don't think it's used improperly. Since I could have multiple references to a single value:
$a = 'some string';
$b =& $a;
$c =& $a;

echo $b; // gives 'some string'
echo $c; // gives 'some string'

$a = 'nada';
echo $b; // gives 'nada'

which those 2 concepts, this code

$arr = array('idx1'=>'val1','idx2'=>'val2','idx3'=>'val3');
if (isset($_SESSION['arr']))
{
	$arr =& $_SESSION['arr'];
} else {
	$_SESSION =& $arr;
}

works as intended. If put the if/else inside a function and replace with the appropriate variable along with global definition, why does it break with no reference?  Or is referencing not permitted inside a function? Which I don't see in the manual. As for the example in the manual of 
function foo(&$var)
{
    $var++;
}
I'm not passing the value or the pointer/reference.  I'm passing a string and using the string via variable variables and global and referencing it as variable variables.

Thanks,
Tommy

Sorry, the code in scenario 1 should be:

if (isset($_SESSION['arr']))
{
	$arr =& $_SESSION['arr'];
} else {
	$_SESSION['arr'] =& $arr;
}

Had a long day :D
