username: The Oracle user name.
old_password: The old password.
new_password: The new password to be set.

Beispiele

Beispiel #1 oci_password_change example changing the password of an already connected user


<?php

$dbase      = 'localhost/orcl';
$user       = 'cj';
$current_pw = 'welcome';
$new_pw     = 'geelong';

$c = oci_pconnect($user, $current_pw, $dbase);
oci_password_change($c, $user, $current_pw, $new_pw);
echo "New password is : " . $new_pw . "\n";

?>

Beispiel #2 oci_password_change example of connecting and changing the password in one step


<?php

$dbase      = 'localhost/orcl';
$user       = 'cj';
$current_pw = 'welcome';
$new_pw     = 'geelong';

$c = oci_pconnect($user, $current_pw, $dbase);
if (!$c) {
    $m = oci_error();
    if ($m['code'] == 28001) { // "ORA-28001: the password has expired"
        // Login and reset password at the same time
        $c = oci_password_change($dbase, $user, $current_pw, $new_pw);
        if ($c) {
            echo "New password is : " . $new_pw . "\n";
        }
    }
}

if (!$c) {  // The original error wasn't 28001, or the password change failed
    $m = oci_error();
    trigger_error('Could not connect to database: '. $m['message'], E_USER_ERROR);
}

// Use the connection $c
...

?>

Anmerkungen

Hinweis:
Changing the password either with this function or directly in Oracle should be done carefully. This is because PHP applications may continue to successfully reuse persistent connections by authenticating with the old password. The best practice is to restart all web servers whenever the user password is changed.

Hinweis:
If upgrading the Oracle client libraries or the database from a release prior to 11.2.0.3 to version 11.2.0.3 or higher, oci_password_change may give the error "ORA-1017: invalid username/password" unless both client and server versions are upgraded at the same time.

Hinweis:
The second oci_password_change syntax is available since OCI8 version 1.1.

Hinweis:
In PHP versions before 5.0.0 you must use ocipasswordchange instead. This name still can be used, it was left as alias of oci_password_change for downwards compatability. This, however, is deprecated and not recommended.
