Here is the caller graph for this function:

◆ close()

Log_sqlite::close ( )

Closes the connection to the database if it is still open and we were the ones that opened it.

It is the caller's responsible to close an existing connection that was passed to us via $conf['db'].

Returns: boolean True on success, false on failure. @access public

Reimplemented from Log.

Definition at line 132 of file sqlite.php.

        return ($this->_opened === false);
    }

◆ log()

Log_sqlite::log	(	$message,
		$priority = `null`
	)

Inserts $message to the currently open database.

Calls open(), if necessary. Also passes the message along to any Log_observer instances that are observing this Log.

Parameters

mixed	$message	String or object containing the message to log.
string	$priority	The priority of the message. Valid values are: PEAR_LOG_EMERG, PEAR_LOG_ALERT, PEAR_LOG_CRIT, PEAR_LOG_ERR, PEAR_LOG_WARNING, PEAR_LOG_NOTICE, PEAR_LOG_INFO, and PEAR_LOG_DEBUG.

Returns: boolean True on success or false on failure. @access public
