I will talk about static methods usages in php with some code samples. Lets get started.

Here is a sample, calling static function outside of the class.

<?php
class welcome {
  public static function sayHi() {
    echo "Welcome!";
  }
}

// we can like this -> className::methodName()
welcome::sayHi();
?>

We can also call within the class like this using self::

<?php
class welcome {
	public static function sayHi() {
		echo "Welcome!";
	}
	public function msg() {
		self::sayHi();
	}
}

$hi = new welcome();
$hi->msg();
?>

You can also call static methods from another class like this

<?php
class welcome {
  public static function sayHi() {
    echo "Welcome!";
  }
}

class anotherClass {
  public function msg() {
    welcome::sayHi();
  }
}

$var = new anotherClass();
$var->msg();
?>

You can choose any ways depending upon the situations, the result will still be the same.

Today I will talk about constants which are very useful in development. Before we dive into code samples, there are a few things you have to remember.

1. – It is declared inside a class with the const keyword.
2. – They are case-sensitive. It’s better to name them all upper case letter for best practice.
3. – We can access them back outside of the class with this operator (::)

Let’s see a simple constant and it has been called outside of the class.

<?php
class Welcome {
  const HELLO_MSG = "Hello From Gigas!";
}

echo Welcome::HELLO_MSG;
// this will output "Hello From Gigas!"
?>

And also we can access the constant within the class like this using self keyword.

<?php
class Welcome {
  const HELLO_MSG = "Hello From Gigas!";
  public function sayHello() {
    echo self::HELLO_MSG;
  }
}

$hello = new Welcome();
$goodbye->sayHello();
// this too will output "Hello From Gigas!"
?>
