PHP Bug Type: Class/Object related
Bug description: Reference and key() problem
Description:
------------
When an static array if retourned from a method, for iterating, and
acceded with the key() function, the reference pointer is moved to the end
of the array.
After the loop, the array is unaccessible.
Important : if you add the following line :
$tab = testbug::getTab();
before the loop, the error does not occur.
you can use key(), current(), prev(), there is still a bug.
First tested on windows 5.2.5 version, and still present on 5.2.6
version.
There is no bug on 5.2.3 version.
Thanks for answer.
Reproduce code:
---------------
<?php
class testbug
{
static $tab = array(
'k1' => "elm1",
'k2' => "elm2",
'k3' => "elm3",
'k4' => "elm4",
);
static function getTab()
{
return self::$tab;
}
}
var_dump(testbug::getTab());
foreach (testbug::getTab() as $k => $v)
{
key(testbug::getTab());
}
var_dump(testbug::getTab());
Expected result:
----------------
array
'k1' => string 'elm1' (length=4)
'k2' => string 'elm2' (length=4)
'k3' => string 'elm3' (length=4)
'k4' => string 'elm4' (length=4)
array
'k1' => string 'elm1' (length=4)
'k2' => string 'elm2' (length=4)
'k3' => string 'elm3' (length=4)
'k4' => string 'elm4' (length=4)
Actual result:
--------------
array
'k1' => string 'elm1' (length=4)
'k2' => string 'elm2' (length=4)
'k3' => string 'elm3' (length=4)
'k4' => string 'elm4' (length=4)
null
