New Comment:
This is same as bug #26396 is about.
And this too:
"Note: Also note that foreach operates on a copy of the specified
array and not the array itself. Therefore, the array pointer is not
modified as with the each() construct, and changes to the array element
returned are not reflected in the original array. However, the internal
pointer of the original array is advanced with the processing of the
array. Assuming the foreach loop runs to completion, the array's
internal pointer will be at the end of the array."

Description:
------------
When is used globalized array into recursion method, there is an odd
behaving of foreach on this array in each recursion call. It seems,
that there is no copy of array for foreaching, but reference??? -
internal array pointer is changed in should-be-copy of array.
(ref.(php-manual: foreach): Note: Also note that foreach operates on a
copy of the specified array and not the array itself.)
(btw: it is not bug #22879)
Reproduce code:
---------------
<?php
//--------- ODD -------
echo "<br>global:<br>";
$globvar = array(1,2,3);
Recursion(1);
function Recursion($nr)
{
global $globvar;
echo "in:".$nr."<br>";
foreach($globvar as $valnr)
{
if($valnr > $nr)
{
echo $valnr."<br>";
Recursion($valnr);
}
}
echo "out:".$nr."<br>";
}
//-------- EXPECTED -----------
echo "<br>local:<br>";
$locvar = array(1,2,3);
RecursionLoc(1, $locvar);
function RecursionLoc($nr, $locvar)
{
echo "in:".$nr."<br>";
foreach($locvar as $valnr)
{
if($valnr > $nr)
{
echo $valnr."<br>";
RecursionLoc($valnr, $locvar);
}
}
echo "out:".$nr."<br>";
}
?>
Expected result:
----------------
global:
in:1
2
in:2
3
in:3
out:3
out:2
3
in:3
out:3
out:1
local:
in:1
2
in:2
3
in:3
out:3
out:2
3
in:3
out:3
out:1
Actual result:
--------------
global:
in:1
2
in:2
3
in:3
out:3
out:2
out:1
local:
in:1
2
in:2
3
in:3
out:3
out:2
3
in:3
out:3
out:1
