Changes the user of the specified database connection


maxdb_change_user

maxdb::change_user

(PECL maxdb >= 1.0)

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

Description

Procedural style

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

Object oriented style

bool maxdb::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.

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\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);
?>

The above example will output something similar to:

 Result: a Database running
