Question

I have an array that looks like this:

array
  0 => 
    array
      'title' => string 'Ireland - Wikipedia, the free encyclopedia'
      'url' => string 'http://en.wikipedia.org/wiki/Ireland'
  1 => 
    array
      'title' => string 'Ireland's home for accommodation, activities.'
      'url' => string 'http://www.ireland.com/'

that I want to add a score of 0 to each element. I thought this simple foreach loop would do the trick but…well….it doesn’t :/

public function setScore($result)
{
    foreach($result as $key)
    {
        $key = array('title', 'url', 'score' => 0);
    }
    return $result;
}

Can someone help me out?

Thanks

You create a new array here and do nothing with it:

 foreach($result as $key){
     $key = array('title', 'url', 'score' => 0);
 }

What you want to do is to modify a reference to existing one:

 foreach($result as &$key){  # Note the '&' here
     $key['score'] = 0;
 }
