The property $allowed_actions is not named in camelCase.

This check marks property names that have not been written in camelCase.

In camelCase names are written without any punctuation, the start of each new word being marked by a capital letter. Thus the name database connection string becomes databaseConnectionString.

Coding Style Compatibility introduced by
PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

You can fix this by adding a namespace to your class:

namespace YourVendor;

class YourClass { }

When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.

Documentation introduced by
$deployment is of type object<DataObject>|null, but the function expects a object<DNDeployment>.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

acceptsInteger((integer) $x);

Documentation Bug introduced by
It seems like $this->environment->CurrentBuild() can also be of type false. However, the property $_cache_current_build is declared as type null|object<DNDeployment>. Maybe add an additional type check?

Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a mixed type is assigned to a property that is type hinted more strictly.

For example, imagine you have a variable $accountId that can either hold an Id object or false (if there is no account id yet). Your code now assigns that value to the id property of an instance of the Account class. This class holds a proper account, so the id value must no longer be false.

Either this assignment is in error or a type check should be added for that assignment.

class Id
{
    public $id;

    public function __construct($id)
    {
        $this->id = $id;
    }

}

class Account
{
    /** @var  Id $id */
    public $id;
}

$account_id = false;

if (starsAreRight()) {
    $account_id = new Id(42);
}

$account = new Account();

The method Approver does not exist on object<DNDeployment>? Since you implemented __call, maybe consider adding a @method annotation.

If you implement __call and you know which methods are available, you can improve IDE auto-completion and static analysis by adding a @method annotation to the class.

This is often the case, when __call is implemented by a parent class and only the child class knows which methods exist:

class ParentClass {

    public function __call($method, array $args) {

Bug introduced by
The property Summary does not seem to exist. Did you mean summary_fields?

An attempt at access to an undefined property has been detected. This may either be a typographical error or the property has been renamed but there are still references to its old name.

If you really want to allow access to undefined properties, you can define magic methods to allow access. See the php core documentation on Overloading.

show
Documentation introduced by
The property Branch does not exist on object<DNDeployment>. Since you implemented __get, maybe consider adding a @property annotation.

Since your code implements the magic getter _get, this function will be called for any read access on an undefined variable. You can add the @property annotation to your class or interface to document the existence of this variable.

<?php

/**
 * @property int $x
 * @property int $y
 * @property string $text
 */
class MyLabel
{
    private $properties;

    private $allowedProperties = array('x', 'y', 'text');

    public function __get($name)
    {
        if (isset($properties[$name]) && in_array($name, $this->allowedProperties)) {
            return $properties[$name];
        } else {
            return null;
        }
    }

    public function __set($name, $value)
    {
        if (in_array($name, $this->allowedProperties)) {
            $properties[$name] = $value;
        } else {
            throw new \LogicException("Property $name is not defined.");
        }
    }

}

If the property has read access only, you can use the @property-read annotation instead.

Of course, you may also just have mistyped another name, in which case you should fix the error.

See also the PhpDoc documentation for @property.

Documentation Bug introduced by
The method listMembers does not exist on object<DNProject>? Since you implemented __call, maybe consider adding a @method annotation.

If you implement __call and you know which methods are available, you can improve IDE auto-completion and static analysis by adding a @method annotation to the class.

This is often the case, when __call is implemented by a parent class and only the child class knows which methods exist:

class ParentClass {
    private $data = array();

    public function __call($method, array $args) {
        if (0 === strpos($method, 'get')) {
            return $this->data[strtolower(substr($method, 3))];
        }

        throw new \LogicException(sprintf('Unsupported method: %s', $method));
    }
}

/**
 * If this class knows which fields exist, you can specify the methods here:
 *
 * @method string getName()
 */
class SomeClass extends ParentClass { }

Duplication introduced by
This method seems to be duplicated in your project.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

You can also find more detailed suggestions in the “Code” section of your repository.
