<para>
|
|
<function>mysqli_change_user</function> is used to change the user of the specified
|
|
database connection as given by the <parameter>link</parameter> parameter and sets the
|
|
current database to that specified by the <parameter>database</parameter> parameter.
|
|
This function will return a boolean value indicating if the operation was successful
|
|
or not.
|
|
</para>
|
|
<para>
|
|
If desired, the NULL value may be passed in place of the <parameter>database</parameter>
|
|
parameter resulting in only changing the user and not selecting a database. To select
|
|
a database in this case use the <function>mysqli_select_db</function> function.
|
|
</para>
|
|
<para>
|
|
In order to successfully change users a valid <parameter>username</parameter> and
|
|
<parameter>password</parameter> 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.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
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.
