Description:
------------
Assigning an array to an object field and updating it through use of
__get/__set() no longer works in PHP 5.2 snapshots. This is probably
related to the fix for bug 37667.
Below is a test case based on the one in bug 37667, which is similar to
a larger real code base we have working in PHP 5.1.4.
This test case does not trigger bug 37667 because we create the array
through __set() - bug 37667 does not set the new array this way.
"Expected result" shows output in PHP 5.1.4
"Actual result" shows output in PHP5.2-200607140630
Running on apache 2.2.2.
Reproduce code:
---------------
<?
header("Content-type: text/plain");
class Class1 {
protected $property = array();
function __get($name) {
return $this->property;
}
function __set($name, $val) {
$this->$name = $val;
}
}
class Class2 {}
$r = new Class1();
$r->property = array();
$r->property["what"] = new Class2();
$r->property["who"] = new Class2();
var_dump($r);
?>
Expected result:
----------------
object(Class1)#1 (1) {
["property:protected"]=>
array(2) {
["what"]=>
object(Class2)#2 (0) {
}
["who"]=>
object(Class2)#3 (0) {
}
}
}
Actual result:
--------------
<br />
<b>Fatal error</b>: Cannot use array returned from
Class1::__get('property') in write context in
<b>/devel2/frode/www/_/test37667.php</b> on line <b>16</b><br />
