Example #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 );
?>
以上例程会输出:
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) }
