I have Service directory in my symfony application like below
src/SwipeBundle/Service
Inside of this directory I have class called.
RSA.php
This class has
namespace SwipeBundle\Service;
require_once __DIR__ . 'RSA/Crypt/RSA.php';
require_once __DIR__ . 'RSA/File/X509.php';
class RSA
{
public function privateKey() {
require_once __DIR__ . 'RSA/Certificates/private.txt';
}
public function certificates() {
return require_once __DIR__ . 'RSA/Certificates/pinew.cer';
}
}
and the files directory are
src/SwipeBundle/Service/RSA/Certificates/pinew.cer
src/SwipeBundle/Service/RSA/Certificates/private.txt
src/SwipeBundle/Service/RSA/Crypt/RSA.php
src/SwipeBundle/Service/RSA/File/X509.php
I want to load the classes of this service class to my Controller, like so.
Controller
use SwipeBundle\Service;
class BillsPayController extends Controller
{
public function indexAction() {
$rsa = new \Crypt_RSA();
$hash = new \Crypt_Hash('sha1');
$x509 = new \File_X509();
$privatekey = file_get_contents(RSA()->privateKey());
$x509->loadX509(file_get_contents(RSA()->certificates()));
}
}
I tried also using this one.
use SwipeBundle\Service\RSA;
class BillsPayController extends Controller
{
public function indexAction() {
$a = new RSA();
$a->privateKey();
}
}
Error I encountered.
Attempt result 1: Attempted to load class "Crypt_RSA" from the global namespace.
Did you forget a "use" statement?
Attempt result 2: Compile Error: main(): Failed opening required '/Users/jaysonlacson/Sites/contactless/src/SwipeBundle/ServiceRSA/Crypt/RSA.php' (include_path='.:')
I think you are missing a forward slash like this:
require_once __DIR__ . '/RSA/Crypt/RSA.php';
require_once __DIR__ . '/RSA/File/X509.php';
I'm just guessing, but can you try that?

I am building custom mvc framework from scratch and when I put something something to print in my PageController, application is working, but when I create some other controller and try to print something, it just prints data from PageController.
I think that the problem is on where I put variable protected $currentController = 'PageController'; and $this->currentController = new PageController();.
Now I tried putting $this->currentController = new $this->currentController; and I get this error:
'Fatal error: Uncaught Error: Class 'PageController' not found in C:\xampp\htdocs\php\App\Libraries\Core.php:20 Stack trace: #0 C:\xampp\htdocs\php\public\index.php(7): App\Libraries\Core->__construct() #1 {main} thrown in C:\xampp\htdocs\php\App\Libraries\Core.php on line 20 '.
Also I'm using composer and autoloading with psr-4 and namespacing.
Core.php
namespace App\Libraries;
use App\Controllers\PageController;
class Core
{
protected $currentController = 'PageController';
protected $currentMethod = 'index';
protected $params = [];
public function __construct()
{
$url = $this->getUrl();
if (file_exists('../App/Controllers/' . ucwords($url[0]) . '.php')) {
$this->currentController = ucwords($url[0]);
unset($url[0]);
}
require_once '../App/Controllers/' . $this->currentController . '.php';
$this->currentController = new PageController();
}
public function getUrl()
{
if (isset($_GET['url'])) {
$url = rtrim($_GET['url'], '/');
$url = filter_var($url, FILTER_SANITIZE_URL);
$url = explode('/', $url);
return $url;
}
}
}
PageController.php
namespace App\Controllers;
class PageController
{
public function __construct()
{
echo "Page Loaded!!!";
}
}
PostController.php
namespace App\Controllers;
class PostController
{
public function __construct()
{
echo "Post Controller Loaded!!!";
}
}
index.php (in public folder)
use App\Libraries\Core;
require_once '../App/bootstrap.php';
$init = new Core;
bootstrap.php (in App folder)
<?php
require dirname(__DIR__) . '..\vendor\autoload.php';
I expect when I make some other controller to be able to write something in it and get output without errors or the same data as in PageController.
I pulled your repository down and there were a few things I had to change.
Make sure that your RewriteBase in your .htaccess goes from the correct document root. If you're not using virtual hosts, then you need to use the path from the localhost to the project.
Also, you are still using a require statement before calling the object. You do not need that. Remove it.
At the top, add the namespace to the $currentController property. If $url[0] is set, prefix the namespace like this:
$this->currentController = '\App\Controllers\\' . ucwords($url[0]);
That got the posts controller and page controllers working.
I try to build test project with PatrickLouys/no-framework-tutorial
My Controllers/BaseController.php:
<?php
namespace Example\Controllers;
class BaseController
{
public function test(){
echo 'test';
}
}
And index.php file:
<?php
namespace Example;
require __DIR__.'/vendor/autoload.php';
// come code with routes
case \FastRoute\Dispatcher::FOUND:
$className = $routeInfo[1][0];
$method = $routeInfo[1][1];
$vars = $routeInfo[2];
$class = new $className; <-- load the class specified in the routes
$class->$method($vars);
break;
// some code
When I tried run this code I got error:
Class 'Example\Controllers\BaseController' not found
Can you please tell me where I made a mistake?
I encounterd a little problem with my classes : they simply do not load through my autoloader.
I get this message error :

How to make it works please?
AS I said in the comments check this path
require(C:\wamp64\www\blog\appAutoloader.php/Table/PostsTable.php)
Doesn't look right to me
require(C:\wamp64\www\blog\ [appAutoloader.php] /Table/PostsTable.php)
What's that bit doing there....
Also namespace of App is not app for the folder its App because this may work on Windows but you will find it does not work on Linux. Because Linux paths are case sensitive, and windows are not.
Further this makes little to no sense
require __DIR__ . 'Autoloader.php/' . $class . '.php'; // __DIR__ = the parent folder. Here "app"
Require 2 files? Paths don't work that way, not that I am aware of at least.
On top of that your implementation ignores the _ Typically underlines will be part of the class name but are replaced by directory, this allows a shorter namespace. So for example instead of having a namespace like this
Namespace \APP\Table;
class PostsTable ..
You could have a class in the same place Like so
Namespace \APP;
class Table_PostsTable ..
With a shorter namespace but still located in the App/Table/PostsTable.php file. However, that's just how I read the spec for PSR autoloaders.
PRO TIP
Take this path C:\wamp64\www\blog\appAutoloader.php/Table/PostsTable.php open the file browser on you desktop and see if it pulls up the file by pasting it into the navigation bar. It wont, but you can be sure your path is wrong by eliminating the code.
Trying to understand how namespaces and autoload works on PHP
Server.php located at core/server.php
namespace core\server
{
class Main
{
public function getTopic()
{
$get_params = $_GET;
if (empty($get_params)) $get_params = ['subtopic' => 'test'];
return $get_params;
}
}
}
and Index.php
spl_autoload_register();
use core\server as subtopic;
$test = new subtopic\Main();
var_dump($test);
It cant load the class core/server/Main
Autoload doesn't work that way.
First I will explain how autoloaders works.
spl_autoload_register() is a function to register a function you have in your code to server as an autoloader, the standard function would be:
define('APP_PATH','/path/to/your/dir');
function auto_load($class)
{
if(file_exists(APP_PATH.$class.'.php'))
{
include_once APP_PATH.$class.'.php';
}
}
spl_autoload_register('auto_load');
The constant APP_PATH would be the path to your directory where your code lives.
As you noticed it the param that is passed to spl_autoload_register is the name of my function, this register the function so when a class is instanciated it runs that function.
Now an effective way to use autoloaders and namespaces would be the following:
file - /autoloader.php
define('APP_PATH','/path/to/your/dir');
define('DS', DIRECTORY_SEPARATOR);
function auto_load($class)
{
$class = str_replace('\\', DS, $class);
if(file_exists(APP_PATH.$class.'.php'))
{
include_once APP_PATH.$class.'.php';
}
}
spl_autoload_register('auto_load');
file - /index.php
include 'autoloader.php';
$tree = new Libs\Tree();
$apple_tree = new Libs\Tree\AppleTree();
file - /Libs/Tree.php
namespace Libs;
class Tree
{
public function __construct()
{
echo 'Builded '.__CLASS__;
}
}
file - /Libs/Tree/AppleTree.php
namespace Libs\Tree;
class AppleTree
{
public function __construct()
{
echo 'Builded '.__CLASS__;
}
}
I'm using namespaces and autoload to load my functions in a nicely way, you can use namespace to describe in what dir your class resides and uses the autoloader magic to load it without any problems.
Note: I used the constant 'DS', because in *nix it uses '/' and in Windows it uses '\', with DIRECTORY_SEPARATOR we don't have to worry where the code is going to run, because it will be "path-compatible"
i'm updating my code and trying to use spl_autoload_register but IT SIMPLY DOESN'T WORK!!!
I'm using PHP 5.3.8 - Apache 2.22 on Centos / Ubuntu / Win7 and trying to echo something but i get nothing instead... have been trying to make it work for the last 3 hours with no result... this is driving me mad!!!
class ApplicationInit {
// Constructor
public function __construct() {
spl_autoload_register(array($this, 'classesAutoloader'));
echo 'construct working...!';
}
// Autoloading methods
public function classesAutoloader($class) {
include 'library/' . $class . '.php';
echo 'autoload working...!';
}
}
first echo from __construct works but the "classesAutoloader" doesn't work at all, this class is defined in a php file within a folder and i'm calling it from index.php like follows:
define('DS', DIRECTORY_SEPARATOR);
define('ROOT', getcwd() . DS);
define('APP', ROOT . 'application' . DS);
// Initializing application
require(APP.'appInit.php');
$classAuto = new ApplicationInit();
any help is truly appreciated, thanks in advance!
It seems like you're doing the wrong thing. The function that you pass to spl_autoload_register is what's responsible for loading the class file.
Your code is calling
$classAuto = new ApplicationInit();
but by that time, ApplicationInit is already loaded so the autoload function doesn't get called
A more logical way would be for you to to call
spl_autoload_register(function($class){
include 'library/' . $class . '.php';
});
Then when you call
$something = new MyClass();
And the MyClass is not defined, then it will call your function to load that file and define the class.
What is your problem? Your code is working correctly.
class ApplicationInit {
public function __construct() {
spl_autoload_register(array($this, 'classesAutoloader'));
echo 'construct working...!';
}
public function classesAutoloader($class) {
include 'library/' . $class . '.php';
echo 'autoload working...!';
}
}
$classAuto = new ApplicationInit(); //class already loaded so dont run autoload
$newclass = new testClass(); //class not loaded so run autoload
