Adding to multidimensional array from foreach loop issue

3 Views

I have a foreach loop that iterates through posts and performs actions (such as setting a $distance variable for each). Through a conditional, it needs to do two things, which work independently but I cannot get them to work together.

$results[] = $value; works, as it adds the array ($value)

$results['distance'] = $distance; works by itself but I need to include the $value arrays.

If I have them both in, it results in twice as many arrays as there should be. Distance is supposed to be included in the value. If I do an array_push it works also, but I need to specify the key. 

foreach ($posts as $key => $value) {
  $loop->the_post();
  $result_lat = get_post_meta( $value->ID, 'latitude', true );
  $result_long = get_post_meta( $value->ID, 'longitude', true );
  $distance = round(calc_distance($input_lat, $input_lng, $result_lat, $result_long, "M"));

  // add item to results if within distance
  if ($distance < $_GET['within']) {
    $results[] = $value;
    $results['distance'] = $distance; // add distance to array
  }
}

  1. Use a single multidimensional array to store values:

    foreach ($posts as $key => $value) {
    #..
    $results[$key]["values"] = $value;  
    $results[$key]["distance"] = $distance;
}
#show first row
print_r( array_values($results)[0] );
#iterate
foreach ($results as $r_key => $r_value) {
    print_r($r_value["distance"]);
}

  2. Distance is supposed to be included in the value

    Well then why don’t you just do exactly that – put $distance into $value, before you put $value into the $results array?

    $value['distance'] = $distance;
$results[] = $value;
