Bug description:Unwanted call of the magic __call method
Description:
------------
hello everyone ;
In the documentation, it's said that the magic __call method is called when
an inaccessible member is read. But I've small issue in my current class
with a setter method. When I try to set an Alias on an inexistent member,
the magic __call method is also called.
To solve the problem, I uses a workaround like this in the setter method:
public static function &setAlias($index, &$value) {
$instance = self::getInstance();
// Small workaround to avoid call of magic __get().
$instance->$index = '';
return $instance->$index = &$value;
}
Strange behavior, no ? It's bug or not, if not, can you explain to me the
reason of this statement ? I uses php 5.2.6.
Sorry, for my poor english, I'm french.
Test script:
---------------
class Registry {
protected static $_instance = null;
public static function getInstance() {
if(self::$_instance == null) {
self::$_instance = new self;
}
return self::$_instance;
}
public function __get($index) {
print 'Oh my god...';
}
public static function &setAlias($index, &$value) {
$instance = self::getInstance();
return $instance->$index = &$value;
}
}
class myObject {
protected static $_instance = null;
public static function &getInstance() {
if(self::$_instance == null) {
self::$_instance = new self();
}
return self::$_instance;
}
}
// Here, I want register a `myObject` instance by reference (not by object
identifier)
Registry::setAlias('MyData', myObject::getInstance());
echo '<pre>';
var_dump(Registry::getInstance());
echo '</pre>';
Expected result:
----------------
object(Registry)#2 (1) {
["MyData"]=>
&object(myObject)#1 (0) {
}
}
Actual result:
--------------
Oh my god... Notice: Indirect modification of overloaded property
Registry::$MyData has no effect in /var/www/test.php on line 67 Fatal
error: Cannot assign by reference to overloaded object in /var/www/test.php
on line 67
