PHP: SplFixedArray
SplFixedArray is a data structure provided by the Standard PHP Library(SPL). Works similar to the array but is memory efficient. So when memory consumption is a concern in some part of your PHP application then use SplFixedArray instead of standard array.
PHP: Interface vs Abstract Class vs Trait
Here is a comparison between Interface, Abstract class, and Trait in PHP. Let’s take a look at that side-by-side comparison in a table.
PHP: Abstract Class and Method
An Abstract class is a partially implemented class, as the abstract methods(in the class) do not contain their definition. Those methods are defined in the class that extends the Abstract class.
PHP: Interfaces
Interfaces are contract that ensures the availability of methods/actions that an object must contain. By implementing an interface, a class agrees to contain the definitions of the methods declared in the interface. Interfaces have just the declaration/signature of the method, and the classes(that implement the interface) must have the definition of those methods.
PHP Programming
PHP is one of the most popular programming languages for web application development. PHP is easy to learn and easy to use. PHP stands for “PHP Hypertext Preprocessor”.
PHP: Traits
Traits facilitate code reuse in PHP by providing a simple way to define functionality and reuse those functionalities when we need it. Traits do not comply with the “is-a” nature of inheritance, so traits do not follow the true strict inheritance. As we can use multiple traits in a class, so it compensates for the lack of multiple inheritance nature of PHP.
