In the “describe” callback, you provide multiple tests using the “test” function or “it” function callbacks. How can you run only one “test” or “it” function? One way is to use it.only that depends on…
Use Symfony Security without implementing UserInterface in your domain User object. UserInterface is a contract between your application and Symfony Security. It binds them together so that you can use Symfony Security in your application….
Getter and setters, also known as accessors and mutators; and predicates are very useful to attain abstractions and encapsulation in object-oriented programming. In schools, when you initially learn about these, you start to use them…
I have faced this problem when I was using devilbox with Symfony. The problem was connection to database while running the app, especially the the unit tests. Before I give you the solution, let us…
Binary Search algorithm has runtime complexity of O(log n) for worst case and average case, and O(1) for the best case. There is recursive and iterative implementation of Binary Search. I will write iterative implementation…
Quick Sort is the most widely used sorting algorithm. It is official sorting algorithm in PHP (sort). It has average case runtime O(n log n) and worst case O(n^2). If you want to understand how…
Merge sort guarantees O(n log n) runtime. It is usually compared with Quick Sort and is likely a second best sorting algorithm after Quick Sort in most cases. Quicksort is average case O(n log n),…
Even with similar complexity of O(n^2) as Bubble Sort, selection sort is preferred when memory writes are too expensive. If you want to understand how it works, jump to bottom of the page to see…
Bubble sort algorithm has a runtime complexity of O(n2) and space complexity of O(1). Find below two implementations of Bubble Sort in PHP. If you want to understand how it works, jump to bottom of…
UPDATE: With improvement in my ideas, experience and knowledge, I no longer agree with having an interface for a Value Object. I don’t write interface for Value Objects anymore. The most solid reason for this…
