php - Array access 5.2 != 5.3 -

php - Array access 5.2 != 5.3 -

i have piece of code:

$data = array(); $data['foo'] = 'tst'; $data['bar'] = array('asd'); $data['user'] = new stdclass(); var_dump(isset($data->foo));

now have executed code on 2 environments.

first:

php 5.2.6-1+lenny16 suhosin-patch 0.9.6.2 (cli) (built: feb 3 2012 08:19:55) copyright (c) 1997-2008 php grouping zend engine v2.2.0, copyright (c) 1998-2008 zend technologies xdebug v2.2.4, copyright (c) 2002-2014, derick rethan

second:

php 5.3.2-1ubuntu4.24 suhosin-patch (cli) (built: apr 4 2014 02:25:37) copyright (c) 1997-2009 php grouping zend engine v2.3.0, copyright (c) 1998-2010 zend technologies xdebug v2.2.5, copyright (c) 2002-2014, derick rethans

on first got result bool(true) on sec bool(false). i've read migration guide (php.net), there nil find behavior.

can explain me behavior?

note:

if alter code to

var_dump(isset($data['foo']))

i same result on both.

as can see here, behaviour changed between 5.2.11 , 5.2.12. release notes 5.2.12 refer bug #50255 isset() , empty() silently casts array object having been fixed.

so, bug in older versions.
