The static method in PHP is same as other OOP languages. Static method should be used only when particular data remains constant for the whole class. As an example, consider that some programmer is making the data of a college and in that every object needs getCollegeName function that returns the same college name for all objects as name of
Starting PHP 5.4+, one of the uses of the static keyword in PHP is to define static anonymous functions / closures.

It was also many times what is needed to destroy some computer components. You see, humans can't feel a static shock until it is several thousand volts strong, but it takes less than 30 volts to damage a sensitive computer component such as a stick of RAM or a processor. How to create static classes in PHP ? A class is a user-defined data type that holds its own data members and member functions that can be accessed and used by creating one or more instances of that class. - Added mp4v2 2.1.0 x86 and x64 static Visual C++ 2017 custom builds. - Added SQLite 3.19.2 x86 and x64 Visual C++ 2017 custom builds. - Improved pingo compression. But in PHP, a class can also contain properties which belong exclusively just to the class and not to any instance of it. These properties are known as static properties, and to differentiate them from instance/object properties they are also called class properties.

PHP - More on Static Methods. A class can have both static and non-static methods. A static method can be accessed from a method in the same class using the self keyword and double colon (::): PHP static methods are most typically used in classes containing static methods only often called utility classes of PHP frameworks like Laravel and CakePHP. Below is the PHP code which shows the use of static methods. Example: This example illustrates the static method in PHP. filter_none. edit close. play_arrow. link New static: The static is a keyword in PHP. Static in PHP 5.3's late static bindings, refers to whatever class in the hierarchy you called the method on. The most common usage of static is for defining static methods. Such methods are part of a class, just like any method, though they may be used even without any such instantiated object. Static variables. Static Variables. The final type of variable scoping that I discuss is known as static. In contrast to the variables declared as function parameters, which are destroyed on the function's exit, a static variable will not lose its value when the function exits and will still hold that value should the function be called again.
The reason to use PHP static properties and methods is that something is really static. "Static", if you're not familiar, is often used in English to mean "unchanging." Sometimes, objects in a system would be truly static in this way. An example I cite a lot is a unit converter. If you had an application where you often needed to
One of the things that often confuses people new to object-oriented PHP is what are called “PHP static methods” and “static properties”. They’re often confusing, because you simply aren’t used to the syntax, which is a PHP double-colon (::) where you might expect an arrow (->). In PHP, static methods are used so that the developer can use the properties and attributes of a static class in the program anywhere needed. To define a static method ‘static’ keyword is used. This keyword is used for the attributes and methods that have to be used in common between the functions and objects in the program. Phan is a static analyzer for PHP that prefers to minimize false-positives. Phan attempts to prove incorrectness rather than correctness. Phan looks for common issues and will verify type compatibility on various operations when type information is available or can be deduced. The static folder is useful as a workaround for a number of less common cases: You need a file with a specific name in the build output, such as manifest.webmanifest . You have thousands of images and need to dynamically reference their paths. PEP-Web Tip of the Day. At the top right corner of every PEP Web article, there is a button to convert it to PDF.
