I am relatively new to using composer and autoload to organize my code. I have a git repository and on my local machine, I set up composer in the root dir of my project. I specified everything in a composer.json needed to get running. Using "composer install", all libraries are automatically installed.
{
"name": "my/repo",
"description": "bla",
"version": "1.2.3",
"require":
{
"php": "5.6.*",
"geraintluff/jsv4": "1.*",
"lcobucci/jwt": "^3.0"
},
"autoload":
{
"psr-4":
{
"MyNamespace\\": "src/"
}
}
}
So - once I ran "composer install" on my local machine, everything was autoloaded in my code. Fine.
But now I need to deploy the whole thing on another linux system. So i pull from the git and run composer install. All the libraries are fetched and the autoload file shows up in vendor/
Yet, I cannot use autoload (yes, I did require_once(__DIR__ . '/../vendor/autoload.php');). Everytime I try to instantiaze a class, i get a
PHP Fatal error: Class 'X' not found in /var/www/bla/x.class.php on line 123
Using use X; does not solve the problem, nor does trying to instantiate the class with its full Namespace name (e.g. $x = new \A\B\X();)
Here is the folder structure (if this matters):
+ src/
| + X.class.php // namespace here is "MyNamespace"
| + Y.class.php // same namespace
+ test/
+ run.php // namespace is "Test"
Here is a snippet of this code (run.php):
<?php namespace Test; // different namespace than the rest of the code
// making the namespace also "\MyNamespace" wouldnt work either
require_once(__DIR__ . '/../vendor/autoload.php');
use \MyNamespace\Y; // whether this line is here or not does not change the error
session_start();
// same error as with "just" implements Y {}
class SomeClass implements \MyNamespace\Y {
// ...
}
?>
So here, the Fatal error is thrown for the line where Y is extended. No matter if I use the full namespace or not. Only thing that will help is a require_once()...
So, this forces me to go back to the cumbersome way of doing all the require/includes myself!? Is there any way to solve this?
PS: composer dumpautoload wont help
PPS: composer validate shows no errors
For PSR-4 compliance, your file structure should be:
+ src/
| + X.php
| + Y.php
Note the removal of the .class.php suffix. http://www.php-fig.org/psr/psr-4/

I did my best to find a question/answer that applied, but I don't think I understand enough about the autoloader to recognize a suitable answer.
I have a package with the following composer.json:
{
"name": "Pva_agent",
"type":"library",
"description" : "query the pva agent",
"version":"0.1b",
"authors" : [
{
"name":"Ed Greenberg",
"email":"ed#precisionpros.com"
}
],
"minimum-stability":"dev",
"require": {},
"autoload": {
"psr-0": {
"Pva_agent": "."
}
}
}
My directory structure after composer installation of the package:
.
./vendor
./vendor/autoload.php
./vendor/Pva_agent
./vendor/Pva_agent/Agent.php
./vendor/Pva_agent/composer.json
./vendor/Pva_agent/.gitignore
./vendor/composer
./vendor/composer/autoload_psr4.php
./vendor/composer/autoload_real.php
./vendor/composer/autoload_classmap.php
./vendor/composer/autoload_namespaces.php
./vendor/composer/installed.json
./vendor/composer/autoload_static.php
./vendor/composer/ClassLoader.php
./vendor/composer/LICENSE
./composer.lock
./composer.json
./test_pva_agent.php
My test program:
<?php
require_once('vendor/autoload.php');
use Pva_agent\Agent;
$agent = new Agent();
My result:
edg#arthur pva_project $ php test_pva_agent.php
PHP Fatal error: Class 'Pva_agent\Agent' not found in /home/edg/PhpstormProjects/pva_project/test_pva_agent.php on line 6
PHP Stack trace:
PHP 1. {main}() /home/edg/PhpstormProjects/pva_project/test_pva_agent.php:0
edg#arthur pva_project $
I didn't think I needed the 'use' statement, since the autoloader should find the class, right?
Can somebody tell me where the problem lies?
Thanks,
Ed Greenberg
Your Pva_agent library should not sit in the vendor/ directory. This directory should contain only auto-generated data from Composer. This directory is usually not stored in VCS.
You should consider refactoring your directory structure to something similar to this one:
.
|____composer.json
|____composer.lock
|____src
| |____Pva_agent
|____vendor
Your library functionality should be added to src/Pva_agent directory.
Consider to use PSR-4 instead of PSR-0 for autoload functionality, as there is no need to regenerate the autoloader when you add classes. dump-autoloader has to be run in case of PSR-0 after adding classed.
For the directory structure above and the PSR-4 autoloader your composer.json autoload section should look similar to this one:
"autoload": {
"psr-4": { "Pva_agent\\": "src/Pva_agent" }
}
Your library should be auto loaded after this. Your auto-loaded library will be registered under the Pva_agent namespace.
I have just started a new PHP project and right up front, I am running into issues with the autoloader. I searched for the error and consulted the documentation (http://www.php-fig.org/psr/psr-4/), but the issue persists.
Hence, I created a minimal example to narrow down the cause of the error - yet, even with this minimal example, it wont work :(
My folder structure is like this:
+ src/
| + Xyz.php
+ composer.json
+ test.php
Here is my code
composer.json:
{
"name": "sg/ABC",
"description": "abc",
"autoload": {
"psr-4": {
"sg\\ABC\\": "src/"
}
}
}
Xyz.php:
<?php namespace sg\ABC;
class Xyz
{}
?>
test.php:
<?php namespace sg\ABC;
use sg\ABC\Xyz;
$a = new Xyz();
?>
Even though running composer install shows no errors, I immediately get this error when running the code:
$ php test.php
PHP Fatal error: Class 'sg\ABC\Xyz' not found in /dir/x/test.php on line 5
Fatal error: Class 'sg\ABC\Xyz' not found in /dir/x/test.php on line 5
also, running composer dump-autoload (as suggested here and there in this board) does not help
You still need to include the composer autoload.php file to include the loaded libraries.
You need to require the autoloader .. it is usually require_once "path/to/vendor/autoload.php".
I have a question with regards to refactoring a legacy PHP application to be compatible with PHP's PSR-4 standards. I have some classes located at app/classes/ folder which are not yet namespaced properly and I want them to be autoloaded directly when I call composer's vendor/autoload.php. I added a name space according to \<NamespaceName>(\<SubNamespaceNames>)*\<ClassName> and I have tried creating a vendor/myapp/classes/src/ directory under the vendor folder of composer, and executed a dump-autoload command but to no avail. The class doesn't get loaded up and composer can't figure out where to find it. Any pointers on how to do this?
Thanks,
Jan
Thing/s to Note:
-> I don't want to upload the source code to any repository that can be publicly searchable like Packagist as the code is for internal use only.
EDIT:
Here is my composer.json:
...
"autoload":{
"psr-4": {
"Myapp\\" : "Myapp"
}
},
...
But now the structure looks like:
->Myapp
-->Classes
--->Module1
---->submodule.php
--->Module2
---->submodule2.php
--->Module3
---->submodule3.php
--->Config
---->config.db.php
->vendor
-->autoload.php
Here are my issues/questions:
When I try to load submodule.php, which in turn would load submodule2.php and submodule3.php, it would tell me that submodule3.php is not found. The namespace of submodule3.php is Myapp\Classes\Module3 but it says its not found.
I want to include forcibly, config.db.php, on every call of autoload.php
I now figured it out. But the source files will not reside in the /vendor folder, which is okay for my case. If you want to make your files be autoloaded automatically no matter which folder, just add it to the psr-4 block in the composer.json, or create it if it's not yet there. In my composer.json, I have this block on the top level object, which adds the folder I want to get autoloaded and includes also the specific file I want to include, like a config file of some sorts:
...
"autoload":{
"files": [
"somefolder/somefile.php"
],
"psr-4": {
"MyApp\\" : "MyApp"
}
},
...
Which simply means that composer should autoload files residing in the MyApp directory which will also have a namespace of MyApp.
So my folder structure looks like this now:
->MyApp
-->Classes
--->MyClass1.php --> namespace MyApp\Classes classname: MyClass1
-->Components
--->MyClass2.php --> namespace MyApp\Classes classname: MyClass2
->somefolder
-->somefile.php
->vendor
-->autoload.php
->index.php
So if I want to include the file MyClass1.php in index.php, I will just add it like:
include_once( __DIR__ . "/vendor/autoload.php");
use \MyApp\Classes\MyClass1;
$foo = new MyClass1();
$foo->bar();
Hope it helps.
You could approach this by creating your own composer package, adding it to your private git repository, and adding the package to your project's composer.json file:
"require": {
"{your-vendor}/{package-name}": "dev-master"
},
"repositories": [
{
"type": "vcs",
"url": "git#bitbucket.org:{your-vendor}/{package-name}.git"
}
],
Once this is done, run composer update.
I'm trying to use a vendor lib that I created my self. For now I am not able to put it in GIT or SVN so I am trying to get it running without.
This is my directory structure(borrowed from an answer below):
vendor/
ISTlibraries/
Saml2Handler/
src/
Saml2Handler/
In my composer.json I have added
"autoload": {
"psr-0": {
"": "src/",
"Saml2Handler": "vendor/ISTlibraries/Saml2Handler/src/"
}
},
vendor/ISTlibraries/Saml2Handler/src/ is the path to my sourcecode. The class I am trying to get is called Saml2Controller which have this namespace defined
namespace Saml2Handler;
When I try from inside my symfony2 controller to initiate the class I get an error:
FatalErrorException: Error: Class 'Saml2Handler\Saml2Controller' not found in ...
In the controller I try a simple new Saml2Controller and I have written
use Saml2Handler\Saml2Controller;
Where am I going wrong?
The error is expected. I believe that you need the following directory structure:
vendor/
ISTlibraries/
Saml2Handler/
src/
Saml2Handler/ <--- you don't have this
Saml2Controller.php
... in order to have namespace Saml2Handler within your Saml2Handler.php.
Hello guys i have problem with autoloading my class with composer. On Linux all work perfect, but now my boss change env and set Windows. All this work on linux but windows show newbie fatal error:
Fatal error: Class 'AbstractController' not found in
D:\xampp\htdocs\ikacFw\frontController.php on line 7
Common to see my composer.json and stucture for better picture on problem.
Stucture is :
frontController.php
-- vendor
----- Doctrine
----- Ikac
--------- Components
---------- Mvc
------------- Controller
Am trying to load all data from vendor directory.
Composer.json
{
"autoload": {
"psr-0": {
"vendor": ""
}
}
}
Also new component i add manual. Like this :
$loader = require_once 'vendor/autoload.php';
$loader->add('vendor', "Ikac");
Okay next when i try to call :
<?php
require_once 'vendor/autoload.php';
use Ikac\Mvc\Controller;
$a = new AbstractController();
I get error "not found".
My class AbstractController contain defined namespace but dont work again. Like test i do this:
<?php
//vendor/Ikac/Mvc/Controller/AbstractController.php
namespace Ikac\Mvc\Controller;
class AbstractController {
function __construct() {
echo __CLASS__;
}
}
?>
I do from cmd composer dump-autoload, install, but dont work. All this perfect work on linux but here wont. Any idea how to fix this or where i do mistake.
Thanks guys!
SLOVED:
{
"autoload": {
"psr-0": {
"": "vendor/"
}
}
}
Well you should do
<?php
require_once 'vendor/autoload.php';
use Ikac\Mvc\Controller\AbstractController;
$a = new AbstractController();
Your autoloading declaration is wrong.
You will NEVER ever need to include the vendor folder in any autoloading. The vendor folder will contain the autoloading for both all dependencies, and - if configured - for your own classes as well.
You can use Composer to create autoloading for your own classes. Just include the correct info. But from your current info I cannot deduct what would be correct.
