[SOLVED] get all users list using MODX api

$c = $modx->newQuery('modUser');
$users = $c->getCollection($c);

foreach($users as $user){
    $profile = $modx->user->getOne('Profile');
    $fields = $profile->get('fullname');   
    // do the stuff you want for each user as format output or other stuff
    ...
}

$c = $modx->newQuery('modUser');
$users = $modx->getCollection("modUser",$c);

foreach($users as $user){
    $profile = $modx->user->getOne('Profile');
    $fields[] = $profile->get('fullname');  
    // do the stuff you want for each user as format output or other stuff

}

print_r($fields);

<?php
error_reporting(E_ALL);
require_once 'config.core.php';
require_once MODX_CORE_PATH.'model/modx/modx.class.php';
$modx = new modX();
$modx->initialize('web');

$c = $modx->newQuery('modUser');
$c->leftJoin('modUserProfile','Profile');

// add column names that u want to show
$c->select(array(
    'modUser.*',
    'Profile.fullname',
    'Profile.email',
    'Profile.blocked',
));

$users = $modx->getCollection("modUser",$c);

foreach($users as $user){
    $userArray = $user->toArray();
    echo "
".$userArray['username']."==".$userArray['fullname'];
}

?>

$c->where(array(
   'Profile.zip:=' => $zip,
   'AND:Profile.comment:=' => $comment,
   'AND:Profile.fax:=' => $fax
));

foreach($users as $user){
    $userArray = $user->toArray();
    $output .= $modx->getChunk('userListTpl', $userArray);
}
return $output;
