Bug #75868 [NEW]: is_resource() gettype() get_resources() inconsistent result on closed resource
From: bobonov at gmail dot com
Operating system: Ubuntu 17.10
PHP version: 7.2.1
Package: Variables related
Bug Type: Bug
Bug description:is_resource() gettype() get_resources() inconsistent result on closed resource
Description:
------------
Checking the closed resource with:
gettype() return resource (closed)
get_resources() list it as resource
is_resource() return false.
There is an ancient Bug #42797 (php 4.3.6) that is relevant to this bug
Test script:
---------------
<?php
$a = fopen('http://www.google.com',
'r');
echo "$a : the type is " . gettype($a)."\n"; // resource
var_dump(is_resource($a)); // true
print_r(get_resources());
fclose($a);
echo "$a : the type is " . gettype($a)."\n"; // resource closed
var_dump(is_resource($a)); // false
print_r(get_resources());
Expected result:
----------------
I expect is_resource() to return true since get_resources() and
gettype() see the var as resource
Actual result:
--------------
Resource id #6 : the type is resource
bool(true)
Array
(
[1] => Resource id #1
[2] => Resource id #2
[3] => Resource id #3
[4] => Resource id #4
[6] => Resource id #6
)
Resource id #6 : the type is resource (closed)
bool(false)
Array
(
[1] => Resource id #1
[2] => Resource id #2
[3] => Resource id #3
[4] => Resource id #4
[6] => Resource id #6
)
