Status: No Feedback
Bug Type: SimpleXML related
Operating System: Linux
PHP Version: 5.0.3
New Comment:
We are still unable to access properties of a class which extends
SimpleXMLElement.
class SubClass extends SimpleXMLElement
{
var $Layers;
/* Fatal error: Cannot override final method
SimpleXMLElement::__construct() */
# function __construct()
# {
# parent::__construct();
# $this->Layers = array();
# }
function __destruct()
{
parent::__destruct();
unset($this->Layers);
}
function updateID()
{
if (!is_array($this->Layers))
$this->Layers = array();
/* Warning: array_push(): First argument should be an array */
array_push($this->Layers, $this->attributes()->id);
/* Fatal error: SubClass::updateID(): Cannot create unnamed
attribute */
$this->Layers[] = $this->attributes()->id;
}
}
and
$class_vars = get_class_vars(get_class($obj));
var_dump($class_vars);
output:
array(1) {
["Layers"]=>
NULL
}
The problem comes from the fact that when you type $this->Layers,
SimpleXML wants to return the node 'Layers'.

Description:
------------
When i extend SimpleXMLElement there is some weird issue on accessing
variable of the class. (perhaps related to bug #28817, i'm not
completely sure)
Reproduce code:
---------------
<?php
class Reader extends SimpleXMLElement {
public $test;
public function extract()
{
$this->test=array();
var_dump(is_array($this->test));
}
}
$uploadfile="file.xml";
$rs=simplexml_load_file($uploadfile,"Reader");
$rs->extract();
?>
Expected result:
----------------
bool(true)
Actual result:
--------------
bool(false)
------------------------------------------------------------------------
