maxdb->change_user — Changes the user of the specified database connection
Descripción
Procedural style:
Object oriented style (method):
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.
Valores retornados
Devuelve TRUE si todo se llevó a cabo correctamente, FALSE en caso de fallo.
Ejemplos
Example #1 Object oriented style
<?php
/* connect database test */
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if ($result = $maxdb->query("SELECT * FROM dual")) {
$row = $result->fetch_row();
printf("Result: %s\n", $row[0]);
$result->free();
}
/* reset all and select a new database */
if (!$maxdb->change_user("DBADMIN", "SECRET", "DEMODB")) {
printf("Database not running\n");
} else {
printf("Database running\n");
}
/* close connection */
$maxdb->close();
?>
Example #2 Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (!$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);
}
/* reset all and select a new database */
if (!maxdb_change_user($link, "DBADMIN", "SECRET", "DEMODB")) {
printf("Database not running\n");
} else {
printf("Database running\n");
}
/* close connection */
maxdb_close($link);
?>
El resultado del ejemplo seria algo similar a:
Result: a Database running
