MAXDB_CHANGE_USER(3) 1 MAXDB_CHANGE_USER(3) maxdb_change_user - Changes the user of the specified database connection Procedural style SYNOPSIS
bool maxdb_change_user (resource $link, string $user, string $password, string $database) DESCRIPTION
Object oriented style bool maxdb::change_user (string $user, string $password, string $database) maxdb_change_user(3) is used to change the user of the specified database connection as given by the $link parameter and to set the current database to that specified by the $database parameter. In order to successfully change users a valid $username and $password parameters must be provided and that user must have sufficient per- missions to access the desired database. If for any reason authorization fails, the current user authentication will remain. Note Using this command will always cause the current database connection to behave as if was a completely new database connection, regardless of if the operation was completed successfully. This reset includes performing a rollback on any active transactions, closing all temporary tables, and unlocking all locked tables. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Object oriented style <?php /* connect database test */ $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } if ($result = $maxdb->query("SELECT * FROM dual")) { $row = $result->fetch_row(); printf("Result: %s ", $row[0]); $result->free(); } /* reset all and select a new database */ if (!$maxdb->change_user("DBADMIN", "SECRET", "DEMODB")) { printf("Database not running "); } else { printf("Database running "); } /* close connection */ $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (!$link) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } if ($result = maxdb_query($link, "SELECT * FROM dual")) { $row = maxdb_fetch_row($result); printf("Result: %s ", $row[0]); maxdb_free_result($result); } /* reset all and select a new database */ if (!maxdb_change_user($link, "DBADMIN", "SECRET", "DEMODB")) { printf("Database not running "); } else { printf("Database running "); } /* close connection */ maxdb_close($link); ?> The above example will output something similar to: Result: a Database running SEE ALSO
