    Yes.

    To use variables from outside do this:

    
function addslashes2($value) {
     return addslashes($value);
}

$username = addslashes2($username);

    use pass by reference :

    e.g. 

    
$a=3;

ref($a);

function ref(& $v){
   $v=$v+1;
}
echo $a;
    Code (markup):
    or most commonly used by globals

    
global $a;
$a=3;

ref();

function ref(){
  global $a;
  $a=$a+1;
}
echo $a;
    Code (markup):
