Question

Having this php code:

$data['items'] =  array('cars', 'bikes', 'trains');
$data['title']   = $parameters['title'];

foreach ($searchResults as $key => $value)
{
    switch ($key)
    {
        case "_cars":
        foreach ($searchResults['_cars']['items'] as $car)
        {
            preg_match('@video/([^_]+)_([^/]+)@', $car['url'], $match);
            $url = $match[1].'/'.$match[2];
            $url = base_url().'video/'.substr($url,0,1).'d'.substr($url,1);

            $data['data']['car']['url']   = $url;
            $data['data']['car']['title'] = $car['title'];
            $data['data']['car']['img']   = $car['thumbnail_medium_url'];
        }
        break;
        // ................

How can I fix this, or what I am doing wrong because $['data']['car'][...] returns only 1 item for url, title and img outside case "_cars": foreach... but inside it does returns all the data.

Edit:
but I wonder why doing print_r($data) inside the foreach ($searchResults['_cars']['items']... loop returns all data and outside that foreach only 1?

I’m not quite sure what you’re wanting, but at first glance, it looks like each iteration is overwriting the actual value of the array key:

$data['data']['car']['url'] = $url; // this is overwritten each time

You need to create an iterator and use that:

$i = 0;
foreach ($searchResults['_cars']['items'] as $car)
{
  preg_match('@video/([^_]+)_([^/]+)@', $car['url'], $match);
  $url = $match[1].'/'.$match[2];
  $url = base_url().'video/'.substr($url,0,1).'d'.substr($url,1);

  $data['data']['car'][$i]['url']   = $url;
  $data['data']['car'][$i]['title'] = $car['title'];
  $data['data']['car'][$i]['img']   = $car['thumbnail_medium_url'];
  $i++;
}
