Attempted to call function from namespace - Silex PHP - php

Question

I have two doubts about my development in Silex PHP.
usersController.php
namespace myworkplaces\controllers;
use Silex\Application;
use Silex\Api\ControllerProviderInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\HttpKernelInterface;
use myworkplaces\models;
class usersController implements ControllerProviderInterface {
public function connect(Application $app) {
$controllers = $app['controllers_factory'];
$controllers->put('/login', array($this, 'login'))->bind('login');
return $controllers;
}
public function login(Application $app, Request $request) {
$email = $app->escape($request->get('email'));
$password = $app->escape($request->get('password'));
if (!filter_var($email, FILTER_VALIDATE_EMAIL))
return $app->json(array ('type' => 'error', 'message' => 'El email no tiene el formato correcto.'), 202);
if (strlen($password) < 5)
return $app->json(array ('type' => 'error', 'message' => 'La contraseña no puede ser menor a 6 carácteres.'), 202);
if (models\usersModel::checkLogin($app, $email, $password)) {
return $app->json(array ('type' => 'info', 'message' => '¡Ten un buen día!'), 201);
} else {
return $app->json(array ('type' => 'error', 'message' => 'Error en la autentificación.'), 202);
}
}}
usersModel.php
namespace myworkplaces\models;
class usersModel {
function checkEmail($app, $email) {
if (($app['db']->users)->findOne([ 'email' => $email ], [ 'projection' => [ 'email' => 1 ] ]) != NULL) {
return true;
} else {
return false;
}
}
function getDataUser($app, $id) {
return ($app['db']->users)->findOne([ '_id' => new \MongoDB\BSON\ObjectID($id) ]);
}
function checkLogin($app, $email, $password) {
if (!checkEmail($app, $email))
return false;
if (password_verify($password, ($app['db']->users)->findOne([ 'email' => $email ], [ 'projection' => [ 'hashPassword' => 1 ] ])['hashPassword'])) {
$user = getDataUser($app, (string)getID($email));
$app['session']->set('user', array('id' => (string)$user['_id'], 'email' => $user['email'], 'username' => $user['username'], 'superadmin' => $user['superadmin'], 'adminPlaces' => $user['adminPlaces']));
return true;
} else {
return false;
}
}}
To access the checkLogin() function inside the myworkplaces\models namespace and within the class usersModel, I could only access using this call models\usersModel::checkLogin(), and I do not think it's the right thing. Should not I be able to call the function with models\usersModel\checkLogin()?
The second problem is in the function checkLogin, I want to call the checkEmail function inside the same namespace and within the same class, however with a call like checkEmail () you should be able to call it without error. The error that occurs is, Attempted to call function "checkEmail" from namespace "myworkplaces\models". Where is the problem?
I use the autoload of composer
"autoload": {
"psr-4": {
"myworkplaces\\": "src/"
}
}
Thanks!

Here i am assuming no other syntax errors and your class loader is working fine.
In your controller.php
Change this to:
if (models\usersModel::checkLogin($app, $email, $password)) {
This:
if (\myworkplaces\models\usersModel::checkLogin($app, $email, $password)) {
In your usersModel.php
Change this to:
function checkEmail($app, $email) {
This:
public function static checkEmail($app, $email) {
Change this to:
if (!checkEmail($app, $email))
This:
if (!self::checkEmail($app, $email))
