Static electricity has several uses, also called applications, in the real world. One main use is in printers and photocopiers where static electric charges attract the ink, or toner, to the paper. Other uses include paint sprayers, air filters, and dust removal. It can damage electronics Static electricity can also cause damage.

Electro Static Technology, the world leader in passive static control solutions, solves industry challenges posed by static charges in many of today’s sophisticated machines from printers and copiers to sensitive medical equipment, aerospace systems, and automated electronics manufacturing equipment, process machines, kiosks, and many other applications. Static properties. Static properties cannot be accessed through the object using the arrow operator ->. Like any other PHP static variable, static properties may only be initialized using a literal or constant before PHP 5.6; expressions are not allowed. 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.

Note: The PHP 4 method of declaring a variable with the var keyword is still supported for compatibility reasons (as a synonym for the public keyword). In PHP 5 before 5.1.3, its usage would generate an E_STRICT warning.

Just throwing my own opinion out there, but from my experience in PHP, for sanity, testability, and scalability's sake, static classes should be pretty much entirely stateless, present a more functional programming-like api than an object oriented one, and generally are best used as accessibility facades for fully instantiated objects or utility wrappers for helpers or similar constructs if Output: 1 1. 2) Static variables are allocated memory in data segment, not stack segment. See memory layout of C programs for details.. 3) Static variables (like global variables) are initialized as 0 if not initialized explicitly. 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

Introduction. In this article I will explain static variables in PHP. A static variable is a variable that has been allocated statically. Static variables only exist within a local scope and it retains its previous value even after function calls; static variables are initialized only one.

Starting PHP 5.4+, one of the uses of the static keyword in PHP is to define static anonymous functions / closures. Read below to understand what they are and how they differ from non-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.
