oci_close() closes the Oracle connection
connection.
Note:
As non-persistent links are closed automatically at the end of script
execution, calling this function is not required. Because of this and
the method the extension uses to handle connection resources,
oci_close() currently provides no actual
functionality.
Returns TRUE on success or FALSE on failure.
Note:
In PHP versions before 5.0.0 you must use ociclose() instead.
This name still can be used, it was left as alias of
oci_close() for downwards compatability.
This, however, is deprecated and not recommended.
