Static methods can be called directly without needing an instance of the class (an object). And, $this-> pseudo-variable is not available inside static methods.However, you can access a special variable called self. The self variable means the current class.

To access a static method use the class name, double colon (::), and the method name:

 

Syntax

     ClassName::staticMethod();

self vs. $this :

The following table illustrates the differences between the self and $this:

$this self
Represents an instance of the class or object Represents a class
Always begin with a dollar ($) sign Never begin with a dollar($) sign
Is followed by the object operator (->) Is followed by the :: operator
The property name after the object operator (->) does not have the dollar ($) sign, e.g., $this->property. The static property name after the :: operator always has the dollar ($) sign.

Syntax of Static method : 

<?php
class ClassName {
  public static function staticMethod() {
    echo "Hello World!";
  }
}
?>

Let's understand with simple example of using static method :

Output :Hello World!
