DBMS_VER	string	The version of the database server, in the form of a string "MM.mm.uuuu" where `MM` is the major version, `mm` is the minor version, and `uuuu` is the update. For example, "08.02.0001" represents major version 8, minor version 2, update 1.
DB_CODEPAGE	int	The code page of the database to which you are connected.
DB_NAME	string	The name of the database to which you are connected.
DFT_ISOLATION	string	The default transaction isolation level supported by the server: UR Uncommitted read: changes are immediately visible by all concurrent transactions. CS Cursor stability: a row read by one transaction can be altered and committed by a second concurrent transaction. RS Read stability: a transaction can add or remove rows matching a search condition or a pending transaction. RR Repeatable read: data affected by pending transaction is not available to other transactions. NC No commit: any changes are visible at the end of a successful operation. Explicit commits and rollbacks are not allowed.
IDENTIFIER_QUOTE_CHAR	string	The character used to delimit an identifier.
INST_NAME	string	The instance on the database server that contains the database.
ISOLATION_OPTION	array	An array of the isolation options supported by the database server. The isolation options are described in the DFT_ISOLATION property.
KEYWORDS	array	An array of the keywords reserved by the database server.
LIKE_ESCAPE_CLAUSE	bool	`true` if the database server supports the use of `%` and `_` wildcard characters. `false` if the database server does not support these wildcard characters.
MAX_COL_NAME_LEN	int	Maximum length of a column name supported by the database server, expressed in bytes.
MAX_IDENTIFIER_LEN	int	Maximum length of an SQL identifier supported by the database server, expressed in characters.
MAX_INDEX_SIZE	int	Maximum size of columns combined in an index supported by the database server, expressed in bytes.
MAX_PROC_NAME_LEN	int	Maximum length of a procedure name supported by the database server, expressed in bytes.
MAX_ROW_SIZE	int	Maximum length of a row in a base table supported by the database server, expressed in bytes.

<?php

$conn = db2_connect('sample', 'db2inst1', 'ibmdb2');

$server = db2_server_info( $conn );

if ($server) {
