Status: Verified
Bug Type: PDO related
Operating System: OS X/Linux
PHP Version: 5.2CVS, 5.3CVS, 6CVS
Assigned To: wez
New Comment:
A simpler case might be:
class MyPDO extends PDO {}
$bar = new PDO("sqlite::memory:", null, null,
array(PDO::ATTR_PERSISTENT => true));
$baz = new MyPDO("sqlite::memory:", null, null,
array(PDO::ATTR_PERSISTENT => true));
var_dump ($bar);
var_dump ($baz);
It looks like it internally caches the object, not just the
connection..
Tested on Fedora Core 6, latest snaps of both 5.2 and 5.3 branch.

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
