I don't want to inspect thousands of lines which are not related to your 'error'. ------------------------------------------------------------------------ [2004-08-14 12:34:43] ahb at ahb dot net Description: ------------ In the code below you can see a class A defining two methods. The "showvarnames" function will show all variable names that are defined in a class and the "showvarvalues" function will show all variable values. If I extend the class A by class B, instantiate a object of class B and call the "showvarvalues" function on this Object, I will get a "Cannot access private property B::$b_private" Error. starting the script below will give the following output : --- cut here --- Variable names b_private b_protected b_public a_protected a_public Variable values Fatal error: Cannot access private property B::$b_private in bug.php(32) : eval()'d code on line 1 --- cut here --- So as you can see the "showvarnames" function shows the correct variable names (a_private is not accessible form B), but I cannot access the variable b_private. Reproduce code: --------------- <? class A { private $a_private; protected $a_protected; public $a_public; function __construct() { $a_private = "private_a"; $a_protected = "protected_a"; $a_public = "public_a"; } function showvarnames () { $arrv = get_class_vars(get_class ($this)); while (list($name, $value) = each ($arrv)) { echo $name."<br>"; } } function showvarvalues () { $arrv = get_class_vars(get_class ($this)); while (list($name, $value) = each ($arrv)) { eval ("\$val = \$this->".$name.";"); echo $name." => ".$val."<br>"; } } } class B extends A { private $b_private; protected $b_protected; public $b_public; function __construct () { $b_private = "private_b"; $b_protected = "protected_b"; $b_public = "public_b"; } } $obj = new B (); echo "Variable names<br>"; $obj->showvarnames (); echo "<br>"; echo "Variable values<br>"; $obj->showvarvalues (); ?> Expected result: ---------------- I would expect that I can access the b_private variable :-) A similar behaviour is described in bug #26350, but I think the behaviour is not what I would expect from a OO language. Even if this works as designed, this is different from other OO languages like Java, C++ and will make the implementation of several algorithms useless, or will force the user not to use private members. Actual result: -------------- --- cut here --- Variable names b_private b_protected b_public a_protected a_public Variable values Fatal error: Cannot access private property B::$b_private in bug.php(32) : eval()'d code on line 1 --- cut here --- ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29674&edit=1
