例

例1 cubrid_get_db_parameter example

<?php
$conn = cubrid_connect("localhost", 33000, "demodb", "dba");

$params = cubrid_get_db_parameter($conn);
var_dump($params);

cubrid_set_autocommit($conn, CUBRID_AUTOCOMMIT_TRUE);
cubrid_set_db_parameter($conn, CUBRID_PARAM_ISOLATION_LEVEL, 2);

$params_new = cubrid_get_db_parameter($conn);
var_dump($params_new);

cubrid_disconnect($conn);
?>

上の例の出力は以下となります。

array(4) {
  ["PARAM_ISOLATION_LEVEL"]=>
  int(3)
  ["PARAM_LOCK_TIMEOUT"]=>
  int(-1)
  ["PARAM_MAX_STRING_LENGTH"]=>
  int(1073741823)
  ["PARAM_AUTO_COMMIT"]=>
  int(0)
}
array(4) {
  ["PARAM_ISOLATION_LEVEL"]=>
  int(2)
  ["PARAM_LOCK_TIMEOUT"]=>
  int(-1)
  ["PARAM_MAX_STRING_LENGTH"]=>
  int(1073741823)
  ["PARAM_AUTO_COMMIT"]=>
  int(1)
}
