LEARN ABOUT PHP
oci_password_change
OCI_PASSWORD_CHANGE(3) OCI_PASSWORD_CHANGE(3)
oci_password_change - Changes password of Oracle's user
SYNOPSIS
bool oci_password_change (resource $connection, string $username, string $old_password, string $new_password)
DESCRIPTION
resource oci_password_change (string $dbname, string $username, string $old_password, string $new_password)
Changes password for user with $username.
The oci_password_change(3) function is most useful for PHP command-line scripts, or when non-persistent connections are used throughout
the PHP application.
PARAMETERS
o $connection
- An Oracle connection identifier, returned by oci_connect(3) or oci_pconnect(3).
o $username
- The Oracle user name.
o $old_password
- The old password.
o $new_password
- The new password to be set.
o $dbname
- The database name.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
oci_password_change(3) 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 . "
";
?>
Example #2
oci_password_change(3) 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 : " . $new_pw . "
";
}
}
}
if (!$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
?>
NOTES
Note
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.
Note
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_pass-
word_change(3) may give the error "ORA-1017: invalid username/password" unless both client and server versions are upgraded at the
same time.
Note
The second oci_password_change(3) syntax is available since OCI8 version 1.1.
Note
In PHP versions before 5.0.0 you must use ocipasswordchange(3) instead. This name still can be used, it was left as alias of
oci_password_change(3) for downwards compatability. This, however, is deprecated and not recommended.
