Convert a piece of code into a php function

This is probably very easy to do, but for some reason I can't figure it out. Let's say I have code like this:

$elements = array('a', 'b', 'c', 'd');

$myValues = array(
    'values' => array(
        'a' => array(
            'xx' => 3,
            'yy' => ''
        ),
        'b' => array(
            'xx' => '',
            'yy' => ''
        ),
        'c' => array(
            'xx' => 8.4,
            'yy' => ''
        ),
        'd' => array(
            'xx' => 18.4,
            'yy' => ''
            )
        )
);

foreach($elements as $elem)
{
    if($myValues['values'][$elem]['xx'] != '')
    {
        if($myValues['values'][$elem]['xx'] < 6)
        {
            $myValues['values'][$elem]['yy'] =  'less than 6';
        }
        elseif($myValues['values'][$elem]['xx'] >= 6 && $myValues['values'][$elem]['xx'] < 15)
        {
            $myValues['values'][$elem]['yy'] =  'between 6 and 16';
        }
        else
        {
            $myValues['values'][$elem]['yy'] = 'greater than 15';
        }

            testFunc($myValues['values'][$elem]['xx']); // This is how I would call my function once I replace the code above
    }
}

As you can see here, I am trying to change the value $myValues['values'][$elem]['yy']

based on some conditions. I want to do this to replace the section of if elseif else

codes with a function that does the same thing.

I've tried something like:

function testFunc($xx)
{
    if($xx < 6)
    {
        $yy = 'less than 6';
    }
    elseif($xx >= 6 && $xx < 15)
    {
        $yy =  'between 6 and 16';
    }
    else
    {
        $yy = 'greater than 15';
    }

    return $yy;
}

But obviously it won't work because I am not changing the value $myValues['values'][$elem]['yy']

inside my function.

NOTE I really want to pass ONLY the value $myValues['values'][$elem]['xx']

inside my function and return the changed value $myValues['values'][$elem]['yy']

.

Can anyone help me with this?

Thank you in advance

EDIT : Rereading the question, I seem to have misunderstood it at first glance. There seems to be no need for links here. Wouldn't this work?

foreach ($elements as $element) {
    $myValues['values'][$element]['yy'] = testFunc($myValues['values'][$element]['xx']);
}


Equally, if it $elements

always matches array_keys($myValues['values'])

, you can use links:

foreach ($myValues['values'] as &$value) {
    $value['yy'] = testFunc($value['xx']);
}

testFunc () function

function testFunc(&$arr) {
  foreach ($arr['values'] as &$values) {
    if ($values['xx'] != '') {
      if ($values['xx'] < 6)
        $values['yy'] = 'less than 6';
      elseif ($values['xx'] >= 6 && $values['xx'] <= 15)
        $values['yy'] = 'between 6 and 15';
      else
        $values['yy'] = 'greater than 15';
      }
    }
  }

Using:



testFunc($myValues);
print_r($myValues);

Output:

Array
(
  [values] => Array
    (

      [a] => Array
        (
          [xx] => 3
          [yy] => less than 6
        )

      [b] => Array
        (
          [xx] => 
          [yy] => 
        )

      [c] => Array
        (
          [xx] => 8.4
          [yy] => between 6 and 15
        )

      [d] => Array
        (
          [xx] => 18.4
          [yy] => greater than 15
        )

    )
