Keywords in PHP :

1. Local:

<?php 
$x = 20;

$y = 40;

function mindstick() {

    local $x, $y;

    $y = $x + $y;

}

mindstick();

echo $y; // outputs 60

?>

2. global: global variable access by using this from within a function.

Example:

<?php 
$x = 5;

$y = 10; 
function mindstick() {

    $GLOBALS['y'] = $GLOBALS['x'] + $GLOBALS['y'];

} 

mindstick();

echo $y; // outputs 15

?>

3. static: all of its variables are deleted when a function is executed.

<?php 
function mindstick() {

    static $x = 0;

    echo $x;

    $x++;

}

mindstick();

mindstick();

mindstick();

?>
