From: Er1c at comcast dot net
Operating system: WinXP
PHP version: 5.0.0b4 (beta4)
PHP Bug Type: Scripting Engine problem
Bug description: 0 typed to NULL causes indexing error
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:
--------------
