Bug description: Constants should only be scalars
Description:
------------
I realize this is 18 months late, but why is this bogus?
It's not only a winxp problem - this happens on all platforms I've tried
(well, win and linux). Nor is this only a PHP5 problem - it's a problem
in the 4 series as well (haven't tested 3).
Either the docs should be changed, or the code behaviour should be
changed. I'm in favor of the latter. While the 'resource' might be
constant - "Resource id #4" might always be "Resource id #4", the state of
that resource might change (file reading problems, db connection problems,
etc.). If the value (or the functional state) of something can change,
that's not really 'constant', is it?
Also, I'm not sure how resource ID numbers are allocated, so this
situation might not happen, but in a resource-intense app, might there be
a chance of using a resource, closing it, opening a new one, and getting
the same 'id' #?
I only found out about this recently, but it seems wrong, and certainly
goes against the documentation.
Reproduce code:
---------------
<?php
$x = mysql_connect('localhost','rt_mgk_user','rt_mgk_pass','rt_mgk');
define('FOO',$x);
if (is_resource(FOO)) {
echo 'foo is a resource';
} else {
echo 'foo is not a resource';
}
?>
Expected result:
----------------
foo is not a resource
Actual result:
--------------
foo is a resource
