Description:
------------
Found PEAR DB's getAssoc() method didn't work correctly when in
DB_FETCHMODE_OBJECT mode. See pear/DB/tests/18get.phpt for that.
I pared it down a bit and then Adam Trachtenberg whittled it down even
farther. Here's what he found:
1) Use an array with a string key: array('a' => 1)
2) Cast it to an object and call get_object_vars()
on the result.
3) Assign this cast object to an array with
multiple elements.
4) Call print_r() on the resulting array.
If I remove any of these, the crash goes away.
Reproduce code:
---------------
<?php
$array = array(1);
$element = (object) array('a' => 1);
get_object_vars($element);
$array[] = $element;
print_r($array);
?>
Expected result:
----------------
Array
(
[0] => 1
[1] => stdClass Object
(
[a] => 1
)
)
Actual result:
--------------
~~~~~ WINDOWS 2000 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Array
(
[0] => 1
[1] => stdClass Object
(
[a] => 1130656883
)
)
~~~~~ OS X 10.3, PHP = beta 3 ~~~~~~~~~
No Output.
~~~~~ OS X 10.3, PHP = recent CVS ~~~~~
Array
(
[0] => 1
[2] => stdClass Object
