PhpDoc: protected property - php

Is it possible to declare protected or private class #property using PhpDoc?
/**
* Class Node
* #package app\models
* #property string $name
*/
class Node
{
}

I don't think so. For #property, public is implied, even if it's read-only or write-only. The point of such tags is about documenting interfaces that can't be inferred. A private/protected variable is really internal to the class so it's only relevant to child classes which should be written as if they already know this. You can still leave a plain docblock immediately before you declare it, though.

Is there any way of using an object type in #property-read and "declare" its attributes?

I want to add a type of object in #property-read and also be able to access its attributes with PhpStorm suggestions.
Here's what I would like to do:
/**
* #property-read object{type: string, schema: string} $request_schema
* #property-read object{type: string, schema: string} $response_schema
*/
class ConfigApiRoutesSchema extends BaseSchema
{
...
}
The reason I'm doing this is because I want to access the attributes type and schema, like this:
$configApiRoutesSchema = new ConfigApiRoutesSchema();
$configApiRoutesSchema->request_schema->type // Here's the problem, type is not suggested
$configApiRoutesSchema->request_schema->schema // schema is also not suggested
This is exactly what I need, but unfortunately this doesn't work for some reason. One solution is to create two classes and specify them as types:
/**
* #property-read string $type
* #property-read string $schema
*/
class RequestSchema {}
/**
* #property-read string $type
* #property-read string $schema
*/
class ResponseSchema {}
/**
* #property-read RequestSchema $request_schema
* #property-read ResponseSchema $response_schema
* #
*/
class ConfigApiRoutesSchema extends BaseSchema {}
Now PhpStorm suggests both schema and type.
But it doesn't seem correct, since RequestSchema and ResponseSchema won't actually be used. So I wonder if there's any way of using annotation with objects without having to create a class to suggest its attributes.
Thank you.
Altho it is possible to specify the shape of arrays, for objects it is not possible to do so (yet). Such a syntax would have been be specified in PSR-5 and PSR-19, but this is not the case.
In the same manner it is not possible to specify the properties of a returned plain object from a method with the #return object annotion.
Apparently the syntax is supported by Psalm, but not in PhpStorm (at very least not yet).
Currently there is a public proposal on the PhpStorm YouTrack board. You might want to upvote that issue to increase it's chance of being included in the next PhpStorm version.

How to use a $this reference inside PHP docblocks

I have a project that utilised MVC where the view file is inherting $this which refers to a view class attached to the controller.
Helper classes have been attached in some of the views and are used like follows:
<?=$this->someHelper->renderSomething()?>
I was hoping to help devs and the IDE out by doing this:
/** #var SomeHelper $this->someHelper */
It's not supported, seemingly. Is there a way to achieve this?
I can only find a workaround at the moment, to declare the helper as a new variable and include a #var statement for that.
It's not possible, you are supposed to type hint the $this instead. If $this is not any concrete class you can type hint, create a fake class/interface instead which will act as a helper to the IDE:
// somewhere outside of your code base, but accessible by the IDE
// use the name of your choice
interface CodeIgniterMvc
{
/**
* #return string
*/
function renderSomething(): string;
/**
* #param array $filter Filtering conditions
* #return \Your\App\Models\User[]
*/
function getUsers(array $filter): array;
}
and in the views:
/** #var $this CodeIgniterMvc **/
Of course include in the repository so every team member can gain such benefits.

Override PHP docblock/annotation of method without overloading (PhpStorm autocompletion)

This is a question about the autocompletion behavior in PhpStorm (and possibly other IDEs) in conjunction with PHP docblocks.
I have to groups of classes in my application. First there are individual classes for various products (CarProduct, FoodProduct etc.), all inheriting from BaseProduct, and the counterpart for individual contracts (CarContract, FoodContract etc.), all inheriting from BaseContract.
<?php
class BaseContract
{
/** #var BaseProduct */
private $product;
/**
* #return BaseProduct
*/
public function getProduct()
{
return $this->product;
}
}
Now I have an instance of CarContract, and I wanna get some CarProduct specific information:
<?php
/* PhpStorm thinks, this is BaseProduct */
$product = $carContract->getProduct();
/* hence, getSpeed() is not available for PhpStorm */
$product->getSpeed();
The autocompletion is not working as I like. There are two workarounds for this, but both are not nice:
Overload getProduct() in the subclass, just with updated #return docblocks
Add /** #var CarProduct $product */ everywhere, where I access the product of a CarContract
Is there a "usual" way to solve something like this, or are my workarounds the only solutions?
PhpStorm does not really allow/does not support doing something like: have the same named class defined elsewhere and just use it as a reference for overriding definitions of real class. You can do that .. but IDE will warn with "multiple definitions of the same class" and it may introduce some weird behaviour/unexpected warnings...
Here is a ticket that ask for such feature: https://youtrack.jetbrains.com/issue/WI-851 -- watch it (star/vote/comment) to get notified on any progress.
Your options are: you can provide correct type hint locally (to local variable) using #var -- you already know it and that's first that you would think of:
<?php
/** #var \CarProduct $product */
$product = $carContract->getProduct();
$product->getSpeed();
Another possible way: instead of overriding actual method .. you can try doing the same but with #method PHPDoc -- will work with your code:
<?php
/**
* My Car Product class
*
* #method \CarProduct getProduct() Bla-bla optional description
*/
class CarContract extends BaseContract ...

Code completion of my classes in netbeans 8

How do I enable code completion for clases and methods I create in code for in netbeans 8.
Thanks,
Dion
You really should google this kinda thing, but I'm in the mood to answer a question :-)
Anyway, most IDE's read your code in pretty much the same way. I can't attest to NetBeans specifically (I use PHPStorm), but the general idea is to make sure you add docblocks to your classes, methods etc. The IDE reads these and can then provide decent code-completion.
<?php
namespace App;
/**
* Class MyClass
* Does some stuff
* #package App
*/
class MyClass extends SomeOtherClass
{
/**
* This is my var
* #var string
*/
public $myVar = 'some val';
/**
* This is my method
* #param string $yourString
* #return SomethingElse
*/
public function myMethod ($yourString)
{
$this->myVar = $yourString;
return new SomethingElse($this->myVar);
}
}
Have a look at the PHPdoc site for the tag syntax. Most IDE's will also have a way of generating this for you as well.

Doctrine entity inheritance and generate:entities command

I have decided to create a 'MappedSuperclass' which will be extended by all other entities to easily share between them two common fields, it looks like this:
/**
* #ORM\MappedSuperclass
*/
abstract class EntityBase {
/**
* #ORM\Column(type="datetime")
*/
protected $created_at;
/**
* #ORM\Column(type="datetime", nullable=true)
*/
protected $updated_at;
/**
* #ORM\PrePersist
* #ORM\PreUpdate
*/
public function updateTimestamps() {
$this->updated_at = new \DateTime('now');
if(is_null($this->created_at)) {
$this->created_at = new \DateTime('now');
}
}
}
My problem is that, after using generate:entities command, script copies to all child classes both fields (as private) as well as updateTimestamps function (which is empty).
Is there any possibility to prevent this behavior? Now i have only 5 entities so its not a big deal to manually delete unneeded code, but it may be pain when project grows up to 20 or more entities.
Or maybe it not the right way to achieve my needs?
If you define a class as abstract it will be interpreted as 'to be implemented'. Thats why you get dummy functions to implement the feature in the actual class. You should just extent a regular class to inherit the fields and the function to update the timestamps.
If you inherit entity classes, you must set the properties of the parent class as private. Child classes may only access them via the getter/setter. I had the same problem a while ago, making properties private works like a charm.
