PHP Keywords : Create and use static properties and methods
The static keyword is used to declare properties and methods of a class as static. Static
properties and methods can be used without creating an instance of the class.
The static keyword is also used to declare variables in a function which keep their value
after the function has ended.
Read more about static methods in our PHP OOP - Static Methods Tutorial.

<?php
function add1() {
static $number = 0;
$number++;
return $number;
}
echo add1();
echo "<br>";
echo add1();
echo "<br>";
echo
add1();
?>
