Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions.
Thank you for your interest in PHP.
You need to set the variables with $this-> too in your constructor.

Description:
------------
When a variable's type is "NULL" (as reported by var_dump()) which
happens when the variable is set to 0, it can no longer be used to
access the 0th position in an array.
In my perticular case, I was attempting this operation:
return $this->serverdata[$this->dataindex][$var];
and needed to do this to get it to run correctly:
return $this->serverdata[intval($this->dataindex)][$var];
I have not throughly tested this bug for other cases where it occurs,
but this is definatly one of the cases.
Reproduce code:
---------------
class testing {
private $dataindex;
private $serverdata;
function __construct() {
$dataindex = 0;
$serverdata =
array(array("name"=>"Er1c","data"=>"foo"),array("name"=>"Bob","data"=>"bar"));
}
function __get($var) {
return $this->serverdata[$this->dataindex][$var];
}
}
$blah = new testing();
echo "Name:" . $blah->name;
Expected result:
----------------
Name: Er1c
Actual result:
--------------
Name:
