When trying to compile my container, I'm getting a "The closure was not found within the abstract syntax tree" exception from jeremeamia/superclosure
Can anyone point me in the right direction of how to debug that? @mnapoli ?
The stack trace isn't exactly helpful
I previously had an error because I was using use ($var) in a closure, but took those out
Bram Van der Sype
Oh, apparently you can't use arrow functions
Jens Prangenberg
Hi everyone, does anybody have knowledge about php-di and zend expressive? "I got Cannot compile closures which import variables using the use keyword'", but i cant find an use statement for the given Delegator. Some ideas?
Bram Van der Sype
@mnapoli still using Slim v3 with the php-di bridge, I upgraded composer and now suddenly getting the error "Class 'AssociativeArrayResolver' not found in /var/www/html/cache/CompiledContainer.php on line 1210"
What could be causing that?
Bram Van der Sype
It happened in the upgrade from php-di 6.1 to 6.2, I'm guessing it has something to do with the change of the closure thingy

Hey all! I'm wondering if I can look up a key within a get()'d array in a autowire()->constructorParameter() somehow. This was my first stab, and I understand it doesn't work because get() is a definition helper, not an immediate lookup:

return [
  'config' => [
    'foo' => 'bar'

  'my.object' => autowire( MyClass::class )
    ->constructorParameter( 'foo', get( 'config' )[ 'foo' ] )

I understand that I could do this with a factory function, but I'm really curious as to if there is a way to do so without one?

How do I use PHP-DI in codeigniter 4
Hi, a query, how can I make a library I have generated, auto-inject into the application that uses it. Is this possible?

I tried something like this:

class CacheServiceProvider implements ServiceProviderInterface

 * @param Container $pimple
public function register(Container $pimple): void
    $pimple[CacheAdapter::class] = [self::class, 'getCache'];
But doesn't work!

Hey guys, I've quick question as I do not understand it from docs.

How does @Inject work? It is said, that I can use it while I do not have control over object creation (i.e. some package).
The Object is created "by hand" somewhere (new Object(itsparams)) - then, I would like to inject some properties from container

I mean, it can't be used in this way, right? It can be used only if object itself is controllered by container?
are you here?
Mohamed Cherif Bouchelaghem
Seems that factory function doens’t accept callable like:
class MyServiceFactory {
   public function __invoke(ContainerInterface $container)
        //creation logic here!
The issue is when compilation is enabled, without compilation everything work fine
Anyone faces this issue before?
to workaround this:
     return (new MyServiceFactory)->__invoke($container);

Hey there, is there a way in PHP-DI to return always a new instance of a class. factory() returns always the same instance, but I need a new instance for every injection.
Anaël Ollier
Hi @obstschale In my understanding of the documentation and the current state of the library, you need to create a factory class yourself for this kind of need, and use something like Container->make(...) in order to force creating a new instance of your class.
Hans-Helge Buerger
Ok. Thx for your help
Hello everybody. I have questions about other files (css/js).
How I connect personal css file ? Thank you.

Hi, how you guys organize dependencies without being a mess?
Split to bunch of arrays and merge them?
Maybe the question was asked before, I just would like to know if there is any pattern to follow?
Anaël Ollier

Hi @cherifGsoul There's no pattern, at least none that I know of. I personnally split the directives in 4 files, based on the "type" of them.

return array_merge(
    include 'sections/10-values.php',
    include 'sections/20-preferences.php',
    include 'sections/30-definitions.php',
    include 'sections/40-virtual.php'

Where "preferences", "definitions" and "virtual" are derived from what you can find in Magento 2 (just because I'm used to it).

  • values: keys are simple strings, often reused later, ex: 'app.base_url' => "some_value"
  • preferences: keys are interface names and define a preference for a given interface, ex: \App\BootstrapInterface::class => \DI\get(\App\Bootstrap::class)
  • definitions: keys are class names and define dependencies, ex: \App\Bootstrap::class => \DI\autowire()->constructorParameter(...)
  • virtual: keys are virtual class names and also define dependencies, ex: 'App\ApiBootstrap::class => \DI\autowire(\App\Bootstrap::class)->constructorParameter(...)
    So far, it covers all my cases :)
Mohamed Cherif Bouchelaghem
@nanawel thanks you for sharing your approach, I really like it and give me ideas
Anaël Ollier
There's a mistake in the last line, the example should be 'App\ApiBootstrap' => \DI\autowire(\App\Bootstrap::class)->constructorParameter(...) (the key should be string, not a ::class)
Mohamed Cherif Bouchelaghem
@nanawel Yeah I got it since is virtual

Plus this page in the docs https://php-di.org/doc/definition-overriding.html gives some insights about organizing big applications definitions.

hi all, anyone know where i can find some documentation about using mocked service in PHPUnit with PHP-DI? we are using the annotations to inject services into our classes and need to be able to inject a mocked version of the service when running out PHPUnit tests
Miika Koskela
Hello, is there a way to get the class name that required specific dependency?
What I try to do, is that when I use Doctrine ORM, I want to use generic repository classes that are retrieved using EntityManager::getRepository("EntityName"). But I don't want to pass EntityManager itself only to get generic repository out of it so I was thinking if I just could typehint to generic EntityRepository class and somehow pass in the required "EntityName"
So I could in my service just typehint to generic EntityManager and get the requiring service class name and the name of the entity from that, e.g. UserService => UserEntity => UserRepository
Miika Koskela
Or should I just manually configure all my services?
Lewis Cowles
Are there any plans for PHP-DI to offer addSingleton or addTrait, a bit like .NET DI? Is there a nice singleton proxy people recommend using to be able to ensure the single-ness of a particular dependency?
Lewis Cowles

I Also do not understand https://php-di.org/doc/definition-overriding.html#decorators chronology. Are the two snippets from different files?

I'd have thought having the same array key, that the definitions would overwrite. I think this might be why they are shown as they are, separate arrays, but something to confirm this would be nice.

For example, could I use this syntax with add if singular? or is addDefinitions the only way this works?

Anaël Ollier
@Lewiscowles1986 To me it's 2 distinct, subsequent calls to addDefinitions(), otherwise of course the second key of the array overwrites the first one.

Hi everyone! In the PhpDoc of ContainerBuilder::enableCompilation() it says for the parameter $containerClass: "Name of the compiled class. Customize only if necessary". Is there any downside in deviating from the default class name, or why does it say to only do that if necessary? The reason is that I would like to have two different containers, which obviously will need to compile to two different filenames.
