search associative array by value

Question

I\'m fetching some JSON from flickrs API. My problem is that the exif data is in different order depending on the camera. So I can\'t hard-code an array number to get, for i

Answer 1

To my knowledge there is no such function. There is array_search, but it doesn't quite do what you want.

I think the easiest way would be to write a loop yourself.

function search_exif($exif, $field)
{
    foreach ($exif as $data)
    {
        if ($data['label'] == $field)
            return $data['raw']['_content'];
    }
}

$camera = search_exif($exif['photo']['exif'], 'model');
