maxdb_change_user

maxdb->change_user

(PECL maxdb >= 1.0)

maxdb_change_user -- maxdb->change_userChanges the user of the specified database connection

설명

Procedural style:

bool maxdb_change_user ( resource $link , string $user , string $password , string $database )

Object oriented style (method):

maxdb
bool change_user ( string $user , string $password , string $database )

maxdb_change_user() 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 permissions 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.
