/**
 * This function returns the CUBRID database parameters or it returns FALSE on
 * failure. It returns an associative array with the values for the following
 * parameters:
 *
 *
 * PARAM_ISOLATION_LEVEL
 * PARAM_LOCK_TIMEOUT
 * PARAM_MAX_STRING_LENGTH
 * PARAM_AUTO_COMMIT
 *
 *
 *
 * Database parameters
 *
 *
 *
 * Parameter
 * Description
 *
 *
 *
 *
 * PARAM_ISOLATION_LEVEL
 * The transaction isolation level.
 *
 *
 * LOCK_TIMEOUT
 * CUBRID provides the lock timeout feature, which sets the waiting
 * time (in seconds) for the lock until the transaction lock setting is
 * allowed. 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_AUTO_COMMIT
 * In CUBRID PHP, auto-commit mode is disabled by default for
 * transaction management. It can be set by using
 * cubrid_set_autocommit.
 *
 *
 *
 *
 *
 *
 * The following table shows the isolation levels from 1 to 6. It consists of
 * table schema (row) and isolation level:
 *
 * Levels of Isolation Supported by CUBRID
 *
 *
 *
 * Name
 * Description
 *
 *
 *
 *
 * SERIALIZABLE (6)
 * In this isolation level, problems concerning concurrency (e.g.
 * dirty read, non-repeatable read, phantom read, etc.) do not
 * occur.
 *
 *
 * REPEATABLE READ CLASS with REPEATABLE READ INSTANCES (5)
 * Another transaction T2 cannot update the schema of table A while
 * transaction T1 is viewing table A.
 * Transaction T1 may experience phantom read for the record R that was
 * inserted by another transaction T2 when it is repeatedly retrieving a
 * specific record.
 *
 *
 * REPEATABLE READ CLASS with READ COMMITTED INSTANCES (or CURSOR STABILITY) (4)
 * Another transaction T2 cannot update the schema of table A while
 * transaction T1 is viewing table A.
 * Transaction T1 may experience R read (non-repeatable read) that was
 * updated and committed by another transaction T2 when it is repeatedly
 * retrieving the record R.
 *
 *
 * REPEATABLE READ CLASS with READ UNCOMMITTED INSTANCES (3)
 * Default isolation level.  Another transaction T2 cannot update
 * the schema of table A  while transaction T1 is viewing table A.
 * Transaction T1 may experience R' read (dirty read) for the record that
 * was updated but not committed by another transaction T2.
 *
 *
 * READ COMMITTED CLASS with READ COMMITTED INSTANCES (2)
 * Transaction T1 may experience A' read (non-repeatable read) for
 * the table that was updated and committed by another transaction  T2
 * while it is viewing table A repeatedly.  Transaction T1 may experience
 * R' read (non-repeatable read) for the record that was updated and
 * committed by another transaction T2 while it is retrieving the record
 * R repeatedly.
 *
 *
 * READ COMMITTED CLASS with READ UNCOMMITTED INSTANCES (1)
 * Transaction T1 may experience A' read (non-repeatable read) for
 * the table that was updated and committed by another transaction T2
 * while it is repeatedly viewing table A.  Transaction T1 may experience
 * R' read (dirty read) for the record that was updated but not committed
 * by another transaction T2.
