For example, MVC frameworks would generally provide a super object or base controller that other controllers must extend to gain access to its dependencies. This **is** Inversion of Control, however, instead of loosening dependencies, this method simply moved them. Dependency Injection allows us to more elegantly solve this problem by only injecting the dependencies we need, when we need them, without the need for any hard coded dependencies at all. -### Dependency Inversion Principle +### S.O.L.I.D. -Dependency Inversion Principle is the "D" in the S.O.L.I.D set of object oriented design principles that states one -should *"Depend on Abstractions. Do not depend on concretions."*. Put simply, this means our dependencies should be -interfaces/contracts or abstract classes rather than concrete implementations. We can easily refactor the above example -to follow this principle. +#### Single Responsibility Principle + +The Single Responsibility Principle is about actors and high-level architecture. It states that “A class should have +only one reason to change.” This means that every class should _only_ have responsibility over a single part of the +functionality provided by the software. The largest benefit of this approach is that it enables improved code +_reusability_. By designing our class to do just one thing, we can use (or re-use) it in any other program without +changing it. + +#### Open/Closed Principle + +The Open/Closed Principle is about class design and feature extensions. It states that “Software entities (classes, +modules, functions, etc.) should be open for extension, but closed for modification.” This means that we should design +our modules, classes and functions in a way that when a new functionality is needed, we should not modify our existing +code but rather write new code that will be used by existing code. Practically speaking, this means that we should write +classes that implement and adhere to _interfaces_, then type-hint against those interfaces instead of specific classes. + +The largest benefit of this approach is that we can very easily extend our code with support for something new without +having to modify existing code, meaning that we can reduce QA time, and the risk for negative impact to the application +is substantially reduced. We can deploy new code, faster, and with more confidence. + +#### Liskov Substitution Principle + +The Liskov Substitution Principle is about subtyping and inheritance. It states that “Child classes should never break +the parent class’ type definitions.” Or, in Robert C. Martin’s words, “Subtypes must be substitutable for their base +types.” + +For example, if we have a `FileInterface` interface which defines an `embed()` method, and we have `Audio` and `Video` +classes which both implement the `embed()` method, then we can expect that the usage of the `embed()` method will always +do the thing that we intend. If we later create a `PDF` class or a `Gist` class which implement the `FileInterface` +interface, we will already know and understand what the `embed()` method will do. The largest benefit of this approach +is that we have the ability to build flexible and easily-configurable programs, because when we change one object of a +type (e.g., `FileInterface`) to another we don't need to change anything else in our program. + +#### Interface Segregation Principle + +The Interface Segregation Principle (ISP) is about _business-logic-to-clients_ communication. It states that “No client +should be forced to depend on methods it does not use.” This means that instead of having a single monolithic interface +that all conforming classes need to implement, we should instead provide a set of smaller, concept-specific interfaces +that a conforming class implements one or more of. + +For example, a `Car` or `Bus` class would be interested in a `steeringWheel()` method, but a `Motorcycle` or `Tricycle` +class would not. Conversely, a `Motorcycle` or `Tricycle` class would be interested in a `handlebars()` method, but a +`Car` or `Bus` class would not. There is no need to have all of these types of vehicles implement support for both +`steeringWheel()` as well as `handlebars()`, so we should break-apart the source interface. + +#### Dependency Inversion Principle + +The Dependency Inversion Principle is about removing hard-links between discrete classes so that new functionality can +be leveraged by passing a different class. It states that one should *"Depend on Abstractions. Do not depend on +concretions."*. Put simply, this means our dependencies should be interfaces/contracts or abstract classes rather than +concrete implementations. We can easily refactor the above example to follow this principle. {% highlight php %} query('SELECT * FROM table'); } -foreach (getAllFoos($db) as $row) { +$results = getAllFoos($db); +foreach ($results as $row) { echo "
