add your own library in a symfony project

Question

I asked a similar questions before but had no right answers. Maybe I did not explain good.

I have 2 classes of my own that I would like to add in symfony project.

seculibs/collections/A.php and seculibs/collections/B.php (it is not on github, it is local).

I would like to add my seculibs folder in the vendor folder and ask symfony to load the classes.

Obviously everything happens in app/autoload.php

I thought that doing this would be okay but not :

$loader->add('seculibs/collections',__DIR__ . '/../vendor/seculibs/collections/');

it still cannot find the classes.

Can somebody tell me exactly what to do? I am with Symfony 2.3.6

Please do not refer to composer.json neither to the UniversalClassLoader and its registerNamespaces method as this is not the class I am dealing with in this autoload.php

Answer 1

So I found the right syntax... It will help some others

$loader->add('seculibs\\collections',__DIR__ . '/../vendor');

Answer 2

Do you HAVE to autoload the classes? I have used my own classes by simply giving them a namespace in my project, and then including them with a use statement in the file that I would like to use them in. For example, I have a class that I put in a custom location within my project, src/My/AppBundle/Utils/MyClass.php, and within the MyClass.php file, I gave the namespace My/AppBundle/Utils

Now in a controller, I include that class with a normal use statement.

use My/AppBundle/Utils/MyClass.php
// .....

class MyController extends Controller {
    // ....
}

This way I can use my class anywhere in my application by referencing the namespace. I know this approach is different from what you may have expected, but it works great.

UPDATE:

It doesn't matter where you put the files. If you want them in the vendor folder, put them there, and give them a namespace that makes sense.

So maybe you have something like this:

// in vendors/MyUtils/Classes/MyClass.php

namespace MyUtils/Classes

class MyClass {
    // ....
}

And then you can still include the class with a use statement like I mentioned.

Answer 3

Look at vendor/composer/ClassLoader.php You can see that the add method expects a prefix as the first argument. You can leave it blank if your classes have no namespace.

Assuming your classes are not namespaced then use:

$loader->add(null,__DIR__ . '/../vendor/seculibs/collections/');

$a = new \A();

If they do have a namespace then just pass the prefix of your namespace to add.

$loader->add('Cerad',__DIR__ . '/../vendor/seculibs/collections/');

namespace Cerad\Collections;
class A {}

$a = new Cerad\Collections\A();

Of course you also have to have the Cerad\Collections directory structure under your vendor directory.

==============================================

Update

If you have in /vendor/seculibs/collectionsA.php:

namespace seculibs\collections;

class A {

Then use:

$loader->add('seculibs',__DIR__ . '/../vendor/');

And

use seculibs\collections\A;

$a = new A();
