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.

Unused Code introduced by
The call to CMB2_REST_Controller_Boxes::prepare_item() has too many arguments starting with $this->request.

This check compares calls to functions or methods with their respective definitions. If the call has more arguments than are defined, it raises an issue.

If a function is defined several times with a different number of parameters, the check may pick up the wrong definition and report false positives. One codebase where this has been known to happen is Wordpress.

In this case you can add the @ignore PhpDoc annotation to the duplicate definition and it will be ignored.

Documentation introduced by
The property $rest_read is declared protected in CMB2_REST. Since you implemented __get(), maybe consider adding a @property or @property-read annotation. This makes it easier for IDEs to provide auto-completion.

Since your code implements the magic setter _set, this function will be called for any write 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.");
        }
    }

}

Since the property has write access only, you can use the @property-write 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.

Bug introduced by
The method get_error_message() does not seem to exist on object<CMB2_REST>.

This check looks for calls to methods that do not seem to exist on a given type. It looks for the method on the type itself as well as in inherited classes or implemented interfaces.

This is most likely a typographical error or the method has been renamed.

Compatibility Best Practice introduced by
Use of global functionality is not recommended; it makes your code harder to test, and less reusable.

Instead of relying on global state, we recommend one of these alternatives:

1. Pass all data via parameters

function myFunction($a, $b) {
    // Do something
}

2. Create a class that maintains your state

class MyClass {
    private $a;
    private $b;

    public function __construct($a, $b) {
        $this->a = $a;
        $this->b = $b;
    }

    public function myFunction() {
        // Do something
    }
}

Documentation introduced by
$cmb is of type object<CMB2>, but the function expects a object<CMB2_REST>.

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);

// we recommend to use
acceptsInteger((integer) $x);

Documentation introduced by
The property cmb_id does not exist on object<CMB2_REST>. 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.
