How to select the necessary elements from json?

Question

PHP

Hello. Help solve the issue.
This json is returned:

How to select all elements (in php) lying in data->images->low_resolution->url.
Thanks for the help.

Answer 1

$array = json_decode($json, true);
$result = array();
foreach($array['data'] as $item) {
  $result[] = $item['images']['low_resolution']['url'];
}

If $item['images'] is also an array, then one more nested loop is needed.

Answer 2

Use array_column()

$urls = array_column(array_column(array_column(array_column(json_decode($jsonString ,true), 'data'), 'images'), 'low_resolution'), 'url');

Not very pretty, but fast and native. You can also try using the JsonPath library

Answer 3

json_decode()
