Bug description: $this gets mangled when extending PDO with persistent
connection
Description:
------------
The class of $this changes after the instantiation of a class which
extends PDO, and which specifies PDO::ATTR_PERSISTENT attribute.
Reproduce code:
---------------
class Foo extends PDO {
function __construct($dsn) {
parent::__construct($dsn, null, null,
array(PDO::ATTR_PERSISTENT =>
true));
}
}
class Baz extends PDO {
function __construct($dsn) {
parent::__construct($dsn, null, null,
array(PDO::ATTR_PERSISTENT =>
true));
}
}
class Bar extends Baz {
function quux() {
echo get_class($this), "\n";
$foo = new Foo("sqlite::memory:");
echo get_class($this), "\n";
}
}
$bar = new Bar("sqlite::memory:");
$bar->quux();
Expected result:
----------------
Bar
Bar
i.e. get_class($this) returns the same value each time
Actual result:
--------------
Bar
Foo
i.e. $this gets mangled
