I am developing with php 5.5, I provided code of my file here
<?php
require_once 'jsonrpcphp/includes/jsonRPCClient.php';
class Client
{
private $remoteMain;
public function __construct($param)
{
$this->remoteMain = new jsonRPCClient('http://
urlTofile/nameOfFile.php');
This codes works absolutely fine but the issue comes when I need to put a namespace for the file as soon as I put a namespace at the top of the file, for example:
<?php
namespace packagename\subPackage;
require_once 'jsonrpcphp/includes/jsonRPCClient.php';
class Client
This error will be displayed
Class 'packagename\subPackage\jsonRPCClient' not found in
The question is this:
how to access a class which is not in my namespace and provided from 3rd parties when I need to have namespaces
thanks in advance
If you're in namespace packagename\subPackage, then new jsonRPCClient refers to the class packagename\subPackage\jsonRPCClient. If you want to use a class from the global namespace, you need to explicitly specify that:
new \jsonRPCClient
Alternatively, explicitly alias the class at the top of the file:
use jsonRPCClient;
new jsonRPCClient(...)
Please RTM: http://php.net/manual/en/language.namespaces.basics.php

I created a new FBLogin.php file in App Folder, added class:
namespace App\FBLogin;
class authlogin {}
Now i want to use this class in my Controller File, so i added:
use App\FBLogin\authlogin;
Now when i am trying to use this class authlogin, it is showing me error Class 'App\FBLogin\authlogin' not found
Is there something i am doing wrong?
Laravel Version: 5.5
Why would you use a lowercase format when naming your classes? Anyway, your namespace inside your app folder should follow your file structure.
If you create your class like below,
namespace App\FBLogin;
class authlogin {
// code here
}
Your file structure must be:
app/
FBLogin/
authlogin.php
Then you can use the class anywhere in your app by declaring the proper namespace
use App\FBLogin\authlogin;
$authlogin = new authlogin();
I'm stuck, i wanted to load external library to my symfony2 project but got error stating that class was not found my app/autoloader.php:
...
$loader->add('Tinify', __DIR__.'/../vendor/tinify/tinify/lib');
...
and my file where i want to use it looks like it:
<?php
namespace XYZ\NewsBundle\Controller;
...
use Tinify;
class NewsController extends Controller{
...
public function displayAction($slug)
{
$em = $this->getDoctrine()->getManager();
$external = new \Tinify();
}
error is as follow The autoloader expected class "Tinify" to be defined in file "xyz/app/../vendor/tinify/tinify/lib\Tinify.php". The file was found but the class was not in it, the class name or namespace probably has a typo.
but file under vendor\tinify\tinify\lib\Tinify.php
namespace Tinify;
const VERSION = "1.3.0";
class Tinify {
...
}
i checked if it really has typo but don't see one
Full qualified class name of Tinify is not Tinify but \Tinify\Tinify. Its namespace + classname.
In you NewsController class you should do:
use \Tinify\Tinify;
Also note the backslash at the beginning of the namespace.
Then in the code you should use just class name and not namespace so also change this:
$external = new \Tinify();
to this:
$external = new Tinify();
Why don't install Tinyfy throught Composer?
composer require tinify/tinify
In this way composer handles de autoload of the library, you don't need to load manually nothing, you only must to make an instance of the class and run
$tinify = new Tinify();
I have a Symfony project to which I added some non-symfony php files containing various classes. But for some reason the classes are not loaded when loading the website, even though the IDE sees them properly.
So, I have a class that needs other classes:
namespace rootspace\FrontBundle\Controller;
use rootspace\FrontBundle\Networks\TwitterOAuth;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
class TwitterController extends Controller
{
public function connectAction(){
// The TwitterOAuth instance
$connection = new TwitterOAuth('abc', '123');
}
}
And then the class which fails to load (that needs yet another file)
namespace rootspace\FrontBundle\Networks;
/* Load OAuth lib. You can find it at http://oauth.net */
//require_once('OAuth.php'); -- should this be commented out?
/**
* Twitter OAuth class
*/
class TwitterOAuth {
/* Contains the last HTTP status code returned. */
}
Lastly, the third file
namespace rootspace\FrontBundle\Networks;
use Symfony\Component\Config\Definition\Exception\Exception;
class OAuthConsumer
{
public $key;
public $secret;
}
(...)
I assume the actual filenames don't matter, right? Nor their structure? PhpStorm sees all the classes properly, I can right-click through them, but it fails when deployed.
Thanks for help
Edit - the whole error message says
Attempted to load class "TwitterOAuth" from namespace "rootspace\FrontBundle\Networks" in D:\Dropbox\project\src\rootspace\FrontBundle\Controller\TwitterController.php line 15. Do you need to "use" it from another namespace?
This is because Symfony's autoloader follows PSR standards (PSR-0, PSR-4) which says that fully qualified (with namespace) class name translates to file location and name. So in fact file names does matter.
So in your case rootspace\FrontBundle\Networks\TwitterOAuth class should be located in rootspace/FrontBundle/Networks directory in file called TwitterOAuth.php
If classes you are using does not follow PSR standards you can also register them manually in app/autoloader.php file

I forgot to add a .php extension to my filename
Im trying to figure out how namespaces works in PHP, but havent really been lucky
Hope somebody could tell me what Im doing wrong here :)
code
require_once 'Vatcode.php';
$Vatcode = new \resource\Vatcode();
Vatcode.php
namespace resource;
require_once Ini::get('path/class').'/Resource.php';
class Vatcode extends Resource {
public function __construct(){
echo 'works!';
}
}
Rescource.php
namespace resource;
class Resource {
}
error
Fatal error: Class 'resource\Ini' not found in Vatcode.php
it's just a problem of namespace.
Your class Vatcode is in namesapce ressource. If, in the file of VatCode declaration you use nameofclas::... or new nameofclass() it will try to get the class in namespace ressource.
If you want to use the class Ini inside your document you have two solutions :
first give the full qualified name :
require \namespace\of\ini\Ini::get('path/class').'/Resource.php';
second using the "use" keyworld before using the get method :
use \namespace\of\ini\Ini;
require_once Ini::get('path/class').'/Resource.php';
In any case, if Ini is in "no namespace" (global namespace is the accurate word) you just has to use the solutions I gave you but only with \Ini instead of \namespace\of\ini\Ini
I have been searching websites to try and get a handle on using PHP namespaces, but they all seem quite vague but what they're trying to do is easy to understand!
My question is: I have a file called people.php and in it is defined class called people. If I create another file called managers.php in the same folder can I define a class again called people which extends the original people class but in the namespace of managers, if so do I have to 'include' the original people.php and if so do I put the include after the writing: namespace managers?
Namespaces are a way to group your related classes in packages. What you describe could best be put under a single namespace like
<?php // people.php
namespace com\example\johnslibrary\people;
abstract class People {
}
and then
<?php // manager.php
namespace com\example\johnslibrary\people;
require_once 'path/to/People.php'; // can better use autoloading though
class Manager extends People {
}
because a Manager is a subclass of People, so there is not much of a reason to put them into their own namespace. They are specialized People.
If you want to Managers to be in their own namespace, you can do so, but have to use the fully qualified name when using the extends keyword, e.g.
<?php // manager.php
namespace com\example\johnslibrary\managers;
require_once 'path/to/People.php';
class Manager extends \com\example\johnslibrary\people\People {
}
or import the People class first
<?php // manager.php
namespace com\example\johnslibrary\managers;
use com\example\johnslibrary\People as People;
require_once 'path/to/People.php';
class Manager extends People {
}
See the PHP Manual on Namespaces for extensive documentation.
// people.php
<?php
namespace People;
class People {}
// managers.php
<?php
namespace Managers;
require_once __DIR__.'/people.php';
class People extends \People\People {}
I have old PHP Class and i need to use it in new PHP file as for example:index.php has to use iClass.php. But before using the OLD iClass.php i have to modify it as below, so that i can use it in index.php.
iClass.php:
namespace ic;
class iClass {
public static function callMeFromClass() {
echo 'OK - you have called me!';
exit;
}
}
index.php
namespace inex;
require_once 'iClass.php';
use ic\iClass;
iClass::callMeFromClass();
