Description:
------------
the odbc_close function always returns null instead of a boolean value as stated in the documentation for odbc_close. In the souce of php_odbc.c there is no RETURN_TRUE or RETURN_FALSE. So is either the docmentation outdated or is in the sourcecode something missing?

Reproduce code:
---------------
$con = odbc_connect("autot32", "db2inst1", "interexa");
$ret = odbc_close($con);
var_dump($ret);


Expected result:
----------------
bool(true)

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