Personal how to go through an array with multiple requests?

Question

I am receiving this object via API and would need to scroll through each of these pages, remembering that each page is a request. Here in this demonstration I am on page 1 each page brings me 50 records and the return shows me that there are 39 pages.. how do I go through these 39 pages making a request to each page? Since I am very grateful for the help of all.

Array

Answer 1

Run a foreach at each level of the array.

foreach($retornoDaAPI['retorno'] as $key => $value){
    foreach($value['contas'] as $key2 => $value2){
       //e assim sucessivamente
    }
}
