What are PHP Static Methods or Static Functions

PHP static methods – In certain instances, viewing methods and properties in terms of a class and not an object is really useful. This can be done using the static keyword. Any method declared to be static can be accessed without creating an object. The class is associated with static functions and not a class instance. Only static methods and static variables are allowed to access these. Static Keyword is used to add a static method to the class.

Declaration of Static Methods

To declare static methods the static keyword is used.

Before the keyword, static can be applied to a visibility modifier. If there is no declaration of visibility, otherwise the exposure must be available. For what visibility, the same rules which we studied in the visibility chapter are added.

The static methods and static properties are not related to any single class object but to the class itself.

You use the :: operator to call a static process outside of class as follows.


How are static methods defined?

Ask yourself a query before specifying a static method: “Is it sensible to name the method without instantiating a new object? “What is happening? If there is a principle that several instances of the class can share, you can remove the code and insert it into a static process. PHP static methods are also used in PHP frameworks utility classes. A utility class is a class comprising only static methods.

The usage of static methods is considered a poor idea. However, in certain situations, it may be helpful to be able to use a technique without the need to create an object. The key situations where the usage of static methods is known while we require them.
