After initializing the Composer autoloader, I want to check the existence of a class:
require_once('vendor/autoload.php');
var_dump(class_exists('PagesController'));
This gives me boolean false, as if my class doesn't exist. However, it does, and is mentioned in the classmap autoloading.
When I add a simple change in the vendor/autoload.php, like adding a var_dump("ballon"), the original check for the PagesController changes to boolean true.
My composer.json file looks like this:
{
"require": {
"propel/propel": "~2.0#dev"
},
"autoload": {
"classmap": ["controllers/", "views/", "views/helpers/", "controllers/components/", "models/", "generated-reversed-database/generated-classes/"]
}
}
I've ran php composer.phar install to generate the autoloader.
require_once('vendor/autoload.php') includes the composer-generated file and is the very first line of code to be executed (it's in my index.php). The PagesController class is located in controllers/.
I'm running php 5.5.9 with Apache2 on an Ubuntu server.
It doesn't even matter whether its a var_dump, a comment (//), or simply a whitespace () that I add in vendor/autoload.php, as long as I add something.
My autoload_classmap.php file:
$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);
return array(
(...lots of classes...),
'PagesController' => $baseDir . '/controllers/PagesController.php'
);
So the class is found and listed.

I'm very new in the field and I'm trying to create my first composer package. I'm following the structure mentioned here but for some reason I always get that the class is not found.
My directory structure is
Project
- src/
-- project
index.php
- vendor/
-- composer/
autoload.php
index.php
So in the main directory Project I have index.php with
<?php
use App\project;
// Autoload files using the Composer autoloader.
require_once __DIR__ . '/vendor/autoload.php';
$entry = new simplePrint();
echo($entry->printHome());
In the directory src/project/ I have index.php with
<?php
namespace App\project;
class simplePrint {
public function printHome() {
return "Hey";
}
}
in composer.json
"autoload": {
"psr-4": {
"App\\": "src/"
}
}
After I create the files, I've made
composer install
composer dump-autoload
What I'm missing here?
Update: after composer update it is still same. The output of the composer update
$ composer update
Loading composer repositories with package information
Updating dependencies
Nothing to modify in lock file
Installing dependencies from lock file (including require-dev)
Nothing to install, update or remove

127.0.0.1:45046 [500]: GET / - Uncaught Error: Class "App\project" not found in ...
PSR-4 says following: The terminating class name corresponds to a file name ending in .php. The file name MUST match the case of the terminating class name.
So you must call your filename simplePrint.php and not index.php.
Here you can read some more information about PSR-4: https://www.php-fig.org/psr/psr-4/
I'm having trouble understanding with doesn't Composer autoloads the packages I required.
My current composer.json file has the following:
{
"require": {
"atlas/orm": "#dev"
},
"require-dev": {
"atlas/cli": "#dev"
}
}
It was supposed to generate a Namespace in the /vendor/composer/autoload_namespaces.php file. But it doesn't. The file only has the following:
// autoload_namespaces.php #generated by Composer
$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);
return array(
'Psr\\Log\\' => array($vendorDir . '/psr/log'),
);
Of course, when I try to use the "require DIR . '/vendor/autoload.php';" to autoload the package and then use its classes, it does not work.
Any idea on how can I solve this?
For requiring in all of the installed dependencies, you have to require 'autoload.php'. For autoloading(PSR-4), in the composer.json file, you have to give a name under which everything will be namespaced and the folder name from which files will be autoloaded.
"Namespace_name\\":"folder_name"
Note: The backslash after the namespace_name needs to be escaped, hence the extra backslash.
Then run composer dump-autoload -o
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've added composer to an existing project that uses the PHP autoload function. Now that composer autoload.php is being used I've removed my old autoload function and I'm trying to load my existing source directory via composer autoload but it isn't picking up any of my existing source classes.
Everything installed by composer loads fine and can be accessed via namespaces etc. so it's just the existing sources in the source directory not being picked up. Any suggestions?
I've looked at a few other of the composer questions on stackoverflow but nothing I've read has solved my problem.
File structure:
index.php
root/
sources/
vendor/
composer.json
media/
Composer autoload:
"autoload": {
"psr-0": {
"" : "sources/"
}
}
There were two things causing issues for me, one was the class file names and the second was a composer command that needed to be run.
My class file names were in the format {classname}.class.php when they need to be in the format that PSR-0 expects which is Classname.php (uppercase first letter) and in turn the classname in the class file follows the file name.
class Classname
{
...
The second issue was that I needed to run the below command.
composer dump-autoload
From composer.org:
If you need to update the autoloader because of new classes in a classmap package for example, you can use "dump-autoload" to do that without having to go through an install or update.
If your code structure is too complex to convert to PSR-* structure, you can use your old autoloader and composer autoload together.
spl_autoload_register( function ( $class ) {
$file = "sources/" . $class . ".class.php";
if ( file_exists( $file ) ) {
require $file;
return;
}
} );
require "vendor/autoload.php";
I am developing a package and I want to store it in the vendor directory before I publish it.
So, The path to say Basset's service provider once it is installed via composer is
/siteroot/vendor/jasonlewis/basset/src/Basset/BassetServiceProvider.php
which composer maps in it's autoloader fine, now If mine is at
/siteroot/vendor/hailwood/databaseconfigloader/src/DatabaseConfigLoader/DatabaseConfigLoaderServiceProvider.php
What do I need to add to the composer.json file to make it generate the autoload mapping correctly?
I can manually edit the autoload_namespaces.php file to add the mapping
'Hailwood\\DatabaseConfigLoader' => $vendorDir . '/hailwood/databaseconfigloader/src/'
and that works, but obviously gets overwritten when I do a composer update, I tried adding
"psr-0": {
"Hailwood\\DatabaseConfigLoader": "src/"
}
to the composer.json but that outputs 'Hailwood\\DatabaseConfigLoader' => $baseDir . '/src/', which doesn't work.
In state, you don't respect PSR-0. So you have two solutions :
Respect PSR-0
You must put your code in /siteroot/vendor/hailwood/databaseconfigloader/src/Hailwood/DatabaseConfigLoader/DatabaseConfigLoaderServiceProvider.php. After that, simply do :
"psr-0":
{
"Hailwood\\DatabaseConfigLoader": "vendor/hailwood/databaseconfigloader/src/"
}
Use classmap autoloading
Just try :
"classmap": ["vendor/hailwood/databaseconfigloader/src/"]
