[FIXED] Passing an array of data to a private function in CodeIgniter/PHP?

Issue

So I thought this should be easy, but, I'm struggling here...

Here's my code:

function xy() {
  $array['var1'] = x;
  $array['var2'] = y;
  echo $this->_z;
}

function _z($array) {
  $xy = $x.$y;
  return $xy;
}

So, why doesn't that seemingly simple code work? I know with views you can pass arrays and the variables are accessible in the views with just their array title, but, why doesn't it work in this case?

Solution

Because function _z is not a view. Call it with $this->_z($array);. Also views are processed by CodeIgniter and variables passed into them. This doesn't work the same way for non-views. PHP won't do that automatically for you.

To load a view make a view file in /system/application/views/ and call it with $this->load->view('my_view_name', $array);

I would rewrite your functions as follows:

function xy()
{
    $x = "some value";
    $y = "some other value";

    echo $this->_z($x, $y);
}

function _z($a, $b)
{
    return $a.$b;
}
