Output and use array elements from a REST Api call in php - php

Question

I am calling a REST Api to get data using curl in php. It gives me the list of data/contents in the api in Array php format.
I was able to get single element value using $resultArray[0]['nid'][0]['value'];. But my goal is to get elements in all contents in the api.
Say I want to get the following elements in the nested arrays.
$resultArray[0]['nid'][0]['value'];
$resultArray[0]['vid'][0]['value'];
$resultArray[0]['cid'][0]['value'];
And use these values in a loop too.
I am trying to search how I can do it loop, and if anyone can provide sample code, that would be appreciated.
Update:
This is the sample result of var_dump:
array(1) {
[0]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(1)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(2)
}
}
["cid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(3)
}
}
["field"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
int(4)
}
}
}
[1]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(11)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(22)
}
}
["cid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(33)
}
}
["field"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
int(44)
}
}
}
[2]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(111)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(222)
}
}
["cid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(333)
}
}
["field"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
int(444)
}
}
}
}
And I want to use these elements values in a loop.
Say my expected result is.
Test1 = "1", "2", "3"
Test2 = "11", "22", "33"
Test3 = "111", "222", "333"
These equivalent numbers should be comming from the element nid, vid, cid.
I dont just want to assign/echo these values in the result as I have array[100s] in one api call.

Since your array is a multidimensional array, you need to have nested foreach loops:
$test = 1;
foreach ($resultArray as $items) {
// Echo the current test number
echo "Test{$test} = ";
$values = [];
foreach ($items as $item) {
// Get the correct value.
if (array_key_exists('value', $item[0])) {
$values[] = $item[0]['value'];
continue;
}
if (array_key_exists('target_id', $item[0])) {
$values[] = $item[0]['target_id'];
continue;
}
}
echo '"' . implode('", "', $values) . '"' . "\n";
$test++;
}
