Question

There is a function which returns a value :

function f($criteria, $extra_return)
{
   return $criteria['activity_code'];
}

I want to set a value to the $extra_return parameter. Is that possible in PHP ?

Answer 1

Yes, you could use Passing by Reference.

function f($criteria, &$extra_return)
{
   $extra_return = 1;
   return $criteria['activity_code'];
}
