Description:
------------
When odbc_execute() is applied to a statement with N placeholders
(where N > 0), the internal array pointer of the supplied $params
array is moved to the Nth position.  Since $params is passed
by-val, it must not be modified, not even its internal pointer.


Test script:
---------------
<?php
$conn = odbc_connect($dsn, $user, $pass);
odbc_exec($conn,"CREATE TABLE test (id INT, name CHAR(24))"); 
$stmt = odbc_prepare($conn,"INSERT INTO test (id, name) VALUES (?, ?)");
$params = [1, "John", "Lim"];
var_dump(key($params));
odbc_execute($stmt, $params);
var_dump(key($params));
?>


Expected result:
----------------
int(0)
int(0)


Actual result:
--------------
int(0)
int(2)
