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();
?>
```
