How to take a value with a foreach loop in a multidimensional array if one of the arrays is not associative?

Question

PHP

In general, getting data from the instagram api, I recoded Json into a multidimensional array, but one of the arrays is not associative. We need to get all images [standart_resolution]->[url] . But due to the fact that the initial array is numbered , I can not write foreach . Tell me friends, I just started learning php, and I put it very clumsily, but I think the essence is clear, thanks in advance
