maxdb_change_user (PECL) maxdb_change_user (no version information, might be only in CVS) maxdb->change_user -- Changes the user of the specified database connection DescriptionProcedural style: bool maxdb_change_user ( resource link, string user, string password, string database ) Object oriented style (method): class 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.
Замечание:
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
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.
ExampleПример 1. Object oriented style |
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if ($result = $maxdb->query("SELECT * FROM dual")) {
$row = $result->fetch_row();
printf("Result: %s\n", $row[0]);
$result->free();
}
if (!$maxdb->change_user("DBADMIN", "SECRET", "DEMODB")) {
printf("Database not running\n");
} else {
printf("Database running\n");
}
$maxdb->close();
?>

Пример 2. Procedural style |
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
if (!$link) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if ($result = maxdb_query($link, "SELECT * FROM dual")) {
$row = maxdb_fetch_row($result);
printf("Result: %s\n", $row[0]);
maxdb_free_result($result);
}
if (!maxdb_change_user($link, "DBADMIN", "SECRET", "DEMODB")) {
printf("Database not running\n");
} else {
printf("Database running\n");
}
maxdb_close($link);
