The cubrid_get_db_parameter function returns the CUBRID system parameters. It returns the CUBRID system parameters or it returns FALSE on failure. It returns an associative array with the values for the following parameters:

  • PARAM_ISOLATION_LEVEL : In CUBRID PHP, you can set the level of transaction isolation by using cubrid_set_db_parameter() function, isolation_level in the $CUBRID/conf/cubrid.conf or the SET TRANSACTION statement. For levels of isolation supported by CUBRID, see "CUBRID SQL Guide > Transaction and Lock > Transaction Isolation Level > SET TRANSACTION ISOLATION LEVEL."
  • PARAM_LOCK_TIMEOUT : CUBRID provides the lock timeout feature, which sets the waiting time for the lock until the transaction lock setting is allowed. You can set lock timeout by using cubrid_set_db_parameter() function, parameter lock_timeout_in_secs in the $CUBRID/conf/cubrid.conf file or the SET TRANSACTION statement (in seconds). The default value of the lock_timeout_in_secs parameter is -1, which means the application client will wait indefinitely until the transaction lock is allowed.
  • PARAM_MAX_STRING_LENGTH : The maximum string length of a parameter
  • PARAM_AUTO_COMMIT : In CUBRID PHP, an auto-commit mode is enabled by default for transaction management. If you want to start a transaction, you should set auto-commit mode to off by using the cubrid_set_autocommit() function. And auto commit modes can be applied only for SELECT statements by setting broker parameters.

array cubrid_get_db_parameter ( $req )

Return Value
  • Success : An associative array that includes the value of CUBRID system parameter
  • Failure : FALSE


printf("%-30s %s ", "CUBRID PHP Version:", cubrid_version());


printf(" ");


$conn = cubrid_connect("localhost", 33088, "demodb");


if (!$conn) {

    die('Connect Error ('. cubrid_error_code() .')' . cubrid_error_msg());



$db_params = cubrid_get_db_parameter($conn);


while (list($param_name, $param_value) = each($db_params)) {

    printf("%-30s %s ", $param_name, $param_value);



printf(" ");


$server_info = cubrid_get_server_info($conn);

$client_info = cubrid_get_client_info();


printf("%-30s %s ", "Server Info:", $server_info);

printf("%-30s %s ", "Client Info:", $client_info);

printf(" ");


$charset = cubrid_get_charset($conn);


printf("%-30s %s ", "CUBRID Charset:", $charset);






The above example will output:


CUBRID PHP Version:       



LOCK_TIMEOUT                        -1

MAX_STRING_LENGTH                   1073741823

PARAM_AUTO_COMMIT                   0


Server Info:              

Client Info:                        8.3.1


CUBRID Charset:                     iso8859-1
