Removing User Data

Starting with version 5.1.5, Horde includes a horde-remove-user-data script that can be run on the command line.

Modifying the default script to remove interactivity

You may want to call the horde-remove-user-data script from another script, providing a user to delete as an argument.
In order to do this, you need to use a modified version of the script.

#!/usr/bin/env php
<?php
/**
 * This script will delete all user data for a given user.

$baseFile = __DIR__ . '/../lib/Application.php';
if (file_exists($baseFile)) {
    require_once $baseFile;
} else {
    require_once 'PEAR/Config.php';
    require_once PEAR_Config::singleton()
        ->get('horde_dir', null, 'pear.horde.org') . '/lib/Application.php';
}
Horde_Registry::appInit('horde', array(
    'authentication' => 'none',
    'cli' => true,
    'user_admin' => true
));

$config=getopt("u");
$user=$config["u"];
$app = null;

$cli->writeln();

try {
    $registry->removeUserData($user, $app);
    $cli->message('Data removed.', 'cli.success');
} catch (Horde_Exception $e) {
    $cli->fatal($e->getMessage());
}

You would call the script like this:
horde-remove-user-data user@domain.com

The examples below are for older Horde versions.

Using the removeUserData APIs of Horde 5

#!/usr/bin/env php
<?php

if (file_exists(__DIR__ . '/../lib/Application.php')) {
    $baseDir = __DIR__;
} else {
    require_once 'PEAR/Config.php';
    $baseDir = PEAR_Config::singleton()
        ->get('horde_dir', null, 'pear.horde.org') . '/kronolith/';
}
require_once  $baseDir . '/lib/Application.php';

Horde_Registry::appInit('horde', array('cli' => true, 'user_admin' => true));

/* remove single user
$value = '<user>';
$cli->writeln('Remove user data of ' . $value);
$registry->removeUserData($value);*/

// remove users on command line
for($i = 1; $i < $argc; ++$i) {
    $value = $argv[$i];
    $cli->writeln('Remove user data of ' . $value);
    $registry->removeUserData($value);
}
