Symfony – Create a service – the right way

Always create service interface for your service. This way you will have better structured code and phpunit testing will be real pleasure.
Also use dependency injection for your repositories in the service.

Service Interface Example

interface UserServiceInterface{
  public function getUsername();
  public function viewAll();

Service Example

class UserService implements UserServiceInterface

  private $entityManager;
  private $userRepository;

  public function __construct(EntityManager $entityManager, UserRepository $userRepository)
    $this->entityManager = $entityManager;
    $this->userRepository = $userRepository;

  public function viewAll()
    return $this->userRepository->findAll();

Repository Example

class UserRepository extends \Doctrine\ORM\EntityRepository
  public function __construct(EntityManager $em, Mapping\ClassMetadata $metadata = null)
      $metadata == null ?
      new Mapping\ClassMetadata(User::class) :

Symfony Security Authorization

There are several way to make authorization on your site with Symfony.
First is in your security.yml on the same level as firewalls tag:

        - { path: ^/admin, roles: ROLE_USER }

This will block all users that don’t have ‘ROLE_USER’ to admin page.

Second option is to use Controller. Inside Method insert:

            throw $this->createAccessDeniedException('GET OUT!');

Or like this:


This will deny access to all users that don’t have ‘ROLE_ADMIN’ to this method.

You can also use annotations:

* @Security("is_granted('ROLE_ADMIN')")

Annotations also work if you add them to the Class. So they will block all users that don’t have ‘ROLE_ADMIN’ to this class.

Symfony Security Authentication

Create Entity named User

< ?php

namespace AppBundle\Entity;

use Symfony\Component\Security\Core\User\UserInterface;
use Doctrine\ORM\Mapping as ORM;

 * @ORM\Entity
 * @ORM\Table(name="user")
class User implements UserInterface
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     * @ORM\Column(type="integer")
    private $id;

     * @ORM\Column(type="string", unique=true)
    private $email;

     * @ORM\Column(type="string")
    private $password;

    private $plainPassword;

    public function getUsername()
        return $this->email;

    public function getRoles()
        return ['ROLE_USER'];

    public function getPassword()
        return $this->password;

    public function getSalt()

    public function eraseCredentials()
        $this->plainPassword = null;

     * @param mixed $email
    public function setEmail($email)
        $this->email = $email;

     * @param mixed $password
    public function setPassword($password)
        $this->password = $password;

     * @return mixed
    public function getPlainPassword()
        return $this->plainPassword;

     * @param mixed $plainPassword
    public function setPlainPassword($plainPassword)
        $this->plainPassword = $plainPassword;
        //This should be here to set value for password to activate doctrine listeners
        $this->password = null;


and generate migration:

#php bin/console doctrine:migrations:diff
#php bin/console doctrine:migrations:migrate

PHP CURL Function Example

This function is populated with all needed data for curl to be executed

function get_curl($site_url){
	$ch = curl_init();

	curl_setopt($ch, CURLOPT_URL, $site_url);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
	curl_setopt($ch, CURLOPT_ENCODING, 'gzip, deflate');

	$headers = array();
	$headers[] = "Accept-Encoding: gzip, deflate, sdch";
	$headers[] = "Accept-Language: en-US,en;q=0.8";
	$headers[] = "Upgrade-Insecure-Requests: 1";
	$headers[] = "User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.59 Safari/537.36";
	$headers[] = "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
	$headers[] = "Referer: $site_url";
	//Set a cookie if needed (you can set other values)
	$headers[] = "Cookie: D_SID=; D_IID=0108BE8F-6C68-31CF-9B9D-4308308DB3A6; D_UID=5A4BCE68-9FD2-3A70-B1DF-376B7D77FD4B; D_ZID=248B7EFC-E23A-3F71-A675-764EA373AEC6; D_ZUID=4DFFC8BD-0AD9-3DE0-94AE-60A57D49736A; D_HID=07EDD9E4-1EDF-3EE3-9D52-B67B5952F6EC";
	$headers[] = "Connection: keep-alive";
	curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

	$result = curl_exec($ch);

	if (curl_error($ch)) {
		$output['status'] = '404';
		$output['msge'] = curl_error($ch);
	} else {
		$output['status'] = 'ok';
		$output['html'] = $result;

	curl_close ($ch);
	return $output;

Send Array to API with POST

function send_curl(array $array)

        $api = 'https://localhost/services/api';
        $action = 'test';
        $password = 'TestPass';

        $ch = curl_init($api);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(
                'password' => $password ,
                'data' => $array,
                'action' => $action,
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        $serverOutput = curl_exec($ch);

        return $serverOutput;

Laravel first steps

Hello, this article is for beginners and will show basic functions.

Installation of Laravel

To begin with instalation we need composer. In console write the following.

composer create-project --prefer-dist laravel/laravel NameOfTheProject

What is artisan

Artisan is the name of the command-line interface included with Laravel. It provides a number of helpful commands for your use while developing your application. It is driven by the powerful Symfony Console component.

Laravel on shared hosting

I will show you not the fastest but easiest way to move Laravel project to shared hosting. You need to be sure that you are using PHP version >= 5.6.4.

First step

First connect to your FTP and create folder outside “public_html”. You can use any name but in this example I will use (“Laravel”) for the name of this folder.

Move everything except “public” folder from your Laravel project to your newly created folder on shared hosting. It will take some time!

In “public_html” folder you need to move files from “public” folder in your Laravel project.

Open index.php file and change the paths to autoload.php and app.php files. They should point to files in the Laravel folder.

Codeigniter 3 – Fast setup

Download and extract codeigniter. In main folder create another folder named assets. There will be additional files for css, js and more.

Setup configuration files. Go to application/config:
– in autoload.php

$autoload['libraries'] = array('database','session');
$autoload['helper'] = array('url','form');

– in config.php

$config['base_url'] = '';
$config['index_page'] = '';
$config['encryption_key'] = 'someEncryptionKey';
$config['sess_save_path'] = sys_get_temp_dir(); //Fix problems with session

– in database.php

'username' => 'root',
'password' => 'rootPassword',
'database' => 'DatabaseName',

– in routes.php

$route['default_controller'] = 'Main_controller';

Step 2 Create Main_controller file in application/controllers
Easiest way is to copy and rename Welcome.php

Step 3 Create .htaccess file in main folder. This is a must for routing!

RewriteEngine On

RewriteCond %{HTTP_HOST} ^ [NC]
RewriteRule ^(.*)$$1 [L,R=301]

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /index\.php(/[^\ ]*)?\ HTTP/
RewriteRule ^index\.php(/(.*))?$$2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
