#50418 [NEW]: self in closures has no class scope
From: crashrox at gmail dot com
Operating system: Linux
PHP version: 5.3.1
PHP Bug Type: Class/Object related
Bug description: self in closures has no class scope
Description:
A closure within a static method loses self scope. When you print
__CLASS__ within a closure it claims to belong to the class. But yet you
cant access anything from that class.
Reproduce code:
---
class Test {
public function do_something() {
$func = function() {
echo 'I belong to: ' . __CLASS__;
return self::do_something_else();
};
return $func();
}
public static function do_something_else() {
return 'I did something else';
}
}
echo Test::do_something();
Expected result:
i belong to: Test
i did something else
Actual result:
--
Test
Fatal error: Cannot access self:: when no class scope is active in
/home/jument/adam/jument/web/index.php on line 7

#44006 [NEW]: next function is not returning correctly
From: crashrox at gmail dot com
Operating system: SunOS 5.10 Generic_127
PHP version: 5.2.5
PHP Bug Type: Arrays related
Bug description: next function is not returning correctly
Description:
Next function is not returning a value when it should be. Tried code
sample below on a linux and windows distro both running PHP 5.2.1 and
received desired results. When tested on SunOS 5.10 and PHP 5.2.4 the
undesired results appeared.
Reproduce code:
---
$array = array(
'key1' = array(
'sub1_key1',
'sub1_key2',
'sub1_key3',
'sub1_key4',
),
'key2' = array(
'sub2_key1',
'sub2_key2',
'sub2_key3',
'sub2_key4',
)
);
foreach($array as $key = $sub_array) {
foreach($sub_array as $sub_val) {
echo $sub_val;
if(next($sub_array))
echo ', ';
}
$next = next($array);
if(is_array($next)) {
echo '';
}
print_r($next);
}
Expected result:
sub1_key1, sub1_key2, sub1_key3, sub1_key4Array
(
[0] = sub2_key1
[1] = sub2_key2
[2] = sub2_key3
[3] = sub2_key4
)
sub2_key1, sub2_key2, sub2_key3, sub2_key4
Actual result:
--
sub1_key1, sub1_key2, sub1_key3, sub1_key4sub2_key1, sub2_key2, sub2_key3,
sub2_key4

#43554 [NEW]: Calling a non static function staticaly causes local assignment
From: crashrox at gmail dot com
Operating system: Tested on Solaris Windows
PHP version: 5.2.5
PHP Bug Type: Class/Object related
Bug description: Calling a non static function staticaly causes local
assignment
Description:
You have two classes (Class1 and Class2). Class1 calls a non static Class2
function with a Class2 variable assignment, but without a return value. The
value set in Class2 is somehow assigned to Class1. If the function was set
to static or the class is instantiated the problem does not occur. See code
example below for better explanation...
Reproduce code:
---
// UNEXPECTED RESULTS
class Class1 {
public function __construct() {
Class2::dosomething();
}
}
class Class2 {
private $somevar;
public function dosomething() {
$this-somevar = 'test';
}
}
$x = new Class1();
print_r($x);
/*
// WORKS CORRECTLY
class Class1 {
public function __construct() {
$x = new Class2();
$x-dosomething();
}
}
class Class2 {
private $somevar;
public function dosomething() {
$this-somevar = 'test';
}
}
$x = new Class1();
print_r($x);
*/
Expected result:
Class1 Object ( )
Actual result:
--
Class1 Object
(
[somevar] = test
)

New Comment:
This is apparently documented in the manual. Took some time to find it
but seems to me it would still be a scope issue. Either way I'm wrong,
so this is closed.
