Returns a string with version information of the Oracle server, which uses
the provided connection.
Returns the version information as a string or FALSE on error.
$conn = oci_connect("scott", "tiger");
echo "Server Version: " . oci_server_version($conn);
In PHP versions before 5.0.0 you must use ociserverversion() instead.
This name still can be used, it was left as alias of
oci_server_version() for downwards compatability.
This, however, is deprecated and not recommended.
