A static variable is the same as a local variable, but it is not destroyed when the function execution is ended.

<?php

function greetme ($name) {

static $greeting=“Hi There”;

$greeting=$greeting.””. $name;

echo $greeting.”! <br>”;

}

greetme (“John’);

greetme (“John’);

greetme (“John’);

?>

Output:

Hi There John!

Hi There John John!

Hi There John John John!

The value of the static $greeting variable is changing after each function call because the $name variable is added to it each time.

Remove the static keyword and the Output: of the function will be the same in the second and the third call

<?php

function greetme ($name) {

$greeting=“Hi There”;

$greeting=$greeting.””. $name;

echo $greeting.”! <br>”;

}

greetme (“John’);

greetme (“John’);

greetme (“John’);

?>

Output:

Hi There John!

Hi There John!

Hi There John!
