Description:
------------
My script successfully connects to oracle, parse and execute simple query (select * from some_table).

Functions oci_fetch_assoc, oci_fetch_array, oci_fetch_row does not return an array. When I try to do "each" with returned array, PHP prints "Variable passed to each() is not an array or object"

oci_num_fields returns right count of columns in result and oci_field_name returns right column names in loop.

Function oci_fetch_all works good, it returns result (array of fields and values), that I expect.



Reproduce code:
---------------
$c=oci_new_connect("a", "b" , "c", "AMERICAN_AMERICA.CL8MSWIN1251");
$s = oci_parse($c, "SELECT NAME from ABONENT");
if (oci_execute($s, OCI_DEFAULT))
{
    while($a=oci_fetch_assoc($s))    {
	while (list($key, $val) = each($a))
	{
	    echo $key." = ".$val."<br>";
	};
    };
};


Expected result:
----------------
Something like that:
NAME = aaa
NAME = bbb
...

Actual result:
--------------
