Best Practice introduced by
It is generally recommended to explicitly declare the visibility for methods.

Adding explicit visibility (private, protected, or public) is generally recommend to communicate to other developers how, and from where this method is intended to be used.

Bug introduced by
The method create() does not exist on Tylercd100\License\Models\License. Did you maybe mean created()?

This check marks calls to methods that do not seem to exist on an object.

This is most likely the result of a method being renamed without all references to it being renamed likewise.

Bug introduced by
There is no parameter named $remaining. Was it maybe removed?

This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function.

Consider the following example. The parameter $italy is not defined by the method finale(...).

/**
 * @param array $germany
 * @param array $island
 * @param array $italy
 */
function finale($germany, $island) {
    return "2:1";

The most likely cause is that the parameter was removed, but the annotation was not.

Documentation introduced by
The property quantity does not exist on object<Tylercd100\License\Models\License>. 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.
