Description:
------------
After connection to Oracle database script runs alter session command to change NLS_NUMERIC_CHARACTERS (',' is decimal separator and '.' is thousands separator). But using the OCI-Collection->append procedure on collection of numbers, all decimals are stripped (the input values into OCI-Collection->append procedure use comma as decimal separator - along to current NLS setting).

Function oci_bind_by_name reflects NLS setting well.

Test script:
---------------
sqlplus> CREATE TYPE username.num_tab IS TABLE OF NUMBER(8,5);

<?PHP

$i_con = oci_connect('username', 'password', 'localhost/devel1');

$i_rs = oci_parse($i_con, "ALTER SESSION SET NLS_NUMERIC_CHARACTERS = ',.'");
oci_execute($i_rs, OCI_DEFAULT);

$i_col = oci_new_collection($i_con, 'NUM_TAB', 'USERNAME');
$i_col->append('1,2');

$i_rs = oci_parse(
    $i_con,
    "DECLARE
        l_nums      username.num_tab := :nums;
    BEGIN
        raise_application_error(-20000, 'First number in collection is: ' || l_nums(1));
    END;"
);
oci_bind_by_name($i_rs, ':nums', $i_col, -1, SQLT_NTY);
oci_execute($i_rs, OCI_DEFAULT);

?>


Expected result:
----------------
Warning: oci_execute() [function.oci-execute]: ORA-20000: First number in collection is: 1,2 ORA-06512: at line 4 in...

Actual result:
--------------
Warning: oci_execute() [function.oci-execute]: ORA-20000: First number in collection is: 1 ORA-06512: at line 4 in...
