Access PHP data from Array within an Array

Question

Newbie PHP question here:

I am using the Vimeo API to access video information and am using PHP to receive the initial array of data. I know how to access the data by using calls like:

echo $array['body']['description'];

But I need to access data like this where 'download' would be accessed via

echo $array['body']['download'];

Specifically where the quality is stated as source as I don't need the other ones. From it I need the link.

"download": [
    {
        "quality": "mobile",
        "type": "video/mp4",
        "width": 480,
        "height": 270,
        "expires": "2015-01-07T18:51:48+00:00",
        "link": "LINK",
        "created_time": "2015-01-02T18:47:11+00:00"
    },
    {
        "quality": "source",
        "type": "source",
        "width": 1920,
        "height": 1080,
        "expires": "2015-01-07T18:51:48+00:00",
        "link": "LINK",
        "created_time": "2015-01-02T18:25:19+00:00"
    }
]

Thank you all for your help!

You can loop through the array $array['body']['download'] then check the value of quality. If it equals source then get the link.

foreach( $array['body']['download'] as $innerArray ){
  if( $innerArray['quality'] === 'source' ){
    echo $innerArray['link'];
  }
}
