➤ The global keyword imports variables from the global scope
into the local scope of a function.
For instance:
$x = 10;
$y = 5;
function additional_first(){
return $x + $y;
}
echo additional_first();
// outputs : Undefined variables $x and $y
function additional_second(){
global $x,$y;
return $x + $y;
}
echo additional_second();
// outputs : 15 by Levani Makhareishvili
