PHP Bug Type: ODBC related
Bug description: odbc_execute modifies the param array
Description:
------------
Calling odbc_execute modifies the input paramList array.
This happens even when I try to make a copy of the array before passing it
to odbc_execute.
Specifically, null parameters are changed to zero length strings.
Reproduce code:
---------------
<?php
function x( $query, $paramList )
{
$result = odbc_execute( $query, $paramList );
$paramList['timg'] = "Tim Gallagher";
}
// change the server and database below to the correct values for your
setup
$connection = 'DRIVER={SQL Server};SERVER=server;DATABASE=database';
$handle = odbc_connect( $connection, '', '' );
$query = odbc_prepare( $handle, "INSERT INTO TEST
(ID,CHECK_LONG,CHECK_VARCHAR) VALUES (?, ?, ? )" );
$paramList[0] = 44;
$paramList[1] = null;
$paramList[2] = null;
echo gettype($paramList[2]) . "\n"; // echos NULL
x( $query, $paramList );
echo gettype($paramList[2]) . "\n"; // echos string
print_r( $paramList )
?>
Expected result:
----------------
NULL
string
Array
(
[0] => 44
[1] =>
[2] =>
)
Actual result:
--------------
NULL
NULL
Array
(
[0] => 44
[1] =>
[2] =>
)
