Looping a Complex Multidimensional Array - php

Question

I'm trying to extract all the variables from a complex array of nutrition results from Neutronix API.
The array is as follows:
Food Array:
Array ( [foods] =>
Array ( [0] => Array (
[food_name] => kale
[brand_name] =>
[serving_qty] => 1
[serving_unit] => cup, chopped
[serving_weight_grams] => 130
[nf_calories] => 36.4
[nf_total_fat] => 0.52
[nf_saturated_fat] => 0.07
[nf_cholesterol] => 0
[nf_sodium] => 29.9
[nf_total_carbohydrate] => 7.32
[nf_dietary_fiber] => 2.6
[nf_sugars] => 1.63
[nf_protein] => 2.47
[nf_potassium] => 296.4
[nf_p] => 36.4
[full_nutrients] => Array (
[0] => Array (
[attr_id] => 203
[value] => 2.47
)
[1] => Array (
[attr_id] => 204
[value] => 0.52
)
[2] => Array (
[attr_id] => 205
[value] => 7.319
)
[3] => Array (
[attr_id] => 207
[value] => 1.131
)
[4] => Array (
[attr_id] => 208
[value] => 36.4
)
[5] => Array (
[attr_id] => 221
[value] => 0
)
[6] => Array (
[attr_id] => 255
[value] => 118.56
)
[7] => Array (
[attr_id] => 262
[value] => 0
)
[8] => Array (
[attr_id] => 263
[value] => 0
)
[9] => Array (
[attr_id] => 268
[value] => 152.1
)
[10] => Array (
[attr_id] => 269
[value] => 1.625
)
[11] => Array (
[attr_id] => 291
[value] => 2.6
)
[12] => Array (
[attr_id] => 301
[value] => 93.6
)
[13] => Array (
[attr_id] => 303
[value] => 1.17

[value] => 23.4
)
[15] => Array (
[attr_id] => 305
[value] => 36.4
)
[16] => Array (
[attr_id] => 306
[value] => 296.4
)
[17] => Array (
[attr_id] => 307
[value] => 29.9
)
[18] => Array (
[attr_id] => 309
[value] => 0.312
)
[19] => Array (
[attr_id] => 312
[value] => 0.2028
)
[20] => Array (
[attr_id] => 315
[value] => 0.5408
)
[21] => Array (
[attr_id] => 317
[value] => 1.17
)
)
[nix_brand_name] =>
[nix_brand_id] =>
[nix_item_name] =>
[nix_item_id] =>
[upc] =>
[consumed_at] => 2017-09-08T22:44:54+00:00
[metadata] => Array ( )
[source] => 1
[ndb_no] => 11234
[tags] => Array (
[item] => kale
[measure] =>
[quantity] => 1.0
[tag_id] => 644
)
[alt_measures] => Array (
[0] => Array (
[serving_weight] => 130
[measure] => cup, chopped
[seq] => 1
[qty] => 1 )
[1] => Array (
[serving_weight] => 130
[measure] => cup
[seq] => 80
[qty] => 1 )
[2] => Array (
[serving_weight] => 2.71
[measure] => tsp
[seq] => 101
[qty] => 1 )
[3] => Array (
[serving_weight] => 8.13
[measure] => tbsp
[seq] => 102
[qty] => 1 )
)
[lat] =>
[lng] =>
[meal_type] => 5
[photo] => Array (
[thumb] => https://d2xdmhkmkbyw75.cloudfront.net/644_thumb.jpg
[highres] => https://d2xdmhkmkbyw75.cloudfront.net/644_highres.jpg
)
[sub_recipe] =>
)
)
)
My PHP Code so far is below. I've inserted comments where I am stuck as to how to get the variables.
I'm also not sure if I'm looping the segments of the array correctly.
foreach ($foods as $food){
foreach($food as $key => $val) {
//get values for each variable
foreach($full_nutrients as $nutrient){
foreach($nutrient as $key => $val){
//get values for each variable
}
}
foreach($metadata as $meta){
$source = $meta['source'];
$ndb_no = $meta['ndb_no'];
foreach($tags as $tag){
$tag_item = $tag['item'];
$tag_measure = $tag['measure'];
$tag_quantity = $tag['quantity'];
$tag_id = $tag['tag_id'];
}
}
foreach($alt_measures as $alt_meaasure){
foreach($alt_meaasure as $key => $val){
//get alt_measures
}
}
foreach($photo as $image){
$image_thumb = $image['thumb'];
$image_highres = $image['highres'];
}
}
}
