Multidimensionnal ARRAY - 3 and 4 levels - php

Question

I have this 3 and 4 multidimensionnal array ($response) which I need to "extract" some values.
Array (
[status] => 200
[response] => Array (
[api_id] => 38229dd9-8c52-11e5-80f6-22000afd0039
[meta] => Array (
[limit] => 20
[next] => /v1/Account/xxx/Call/?limit=20&offset=20
[offset] => 0
[previous] =>
[total_count] => 57 )
[objects] => Array (
[0] => Array (
[answer_time] => 2015-11-13 18:36:19+01:00
[bill_duration] => 10
[billed_duration] => 60
[call_direction] => inbound
[call_duration] => 10
[call_uuid] => dcd94e59-8775-4c81-a4b1-cd5d41d630c6
[end_time] => 2015-11-13 18:36:29+01:00
[from_number] => 3300000000
[initiation_time] => 2015-11-13 18:36:18+01:00
[parent_call_uuid] =>
[resource_uri] => /v1/Account/xxx/Call/dcd94e59-8775-4c81-a4b1-cd5d41d630c6/
[to_number] => 3300000000
[total_amount] => 0.00500
[total_rate] => 0.00500 )
[1] => Array (
[answer_time] => 2015-11-13 15:52:01+01:00 [
bill_duration] => 48
[billed_duration] => 60
[call_direction] => inbound
[call_duration] => 48
[call_uuid] => b2d3de5d-a047-4409-9f7a-825373c38f0a
[end_time] => 2015-11-13 15:52:48+01:00
[from_number] => 3300000000
[initiation_time] => 2015-11-13 15:52:00+01:00
[parent_call_uuid] =>
[resource_uri] => /v1/Account/xxx/Call/b2d3de5d-a047-4409-9f7a-825373c38f0a/
[to_number] => 3300000000
[total_amount] => 0.00500
[total_rate] => 0.00500 )
...
In the [meta] array, I need the [total_count] value and for the [object] array, I'd like to get all the values to disaply them in a row (each object is a new row).
I have tried foreach within foreach or access datas with $response[0][0][0] but nothing do.
If someone could lead me to the solution...
Thanks a lot !!

Answer 1

You can access the meta array through $response['response']['meta']. As you can see from your array, both response and meta are keys, and so is total_count. Hence, accessing total count is done by $response['response']['meta']['total_count'].
To then loop through all your objects, simply do
foreach ($response['response']['objects'] as $object) {
print_r($object);
}
You can also access every attribute of the object individually by using the array keys:
foreach ($response['response']['objects'] as $object) {
echo $object['answer_time'];
echo $object['bill_duration'];
echo $object['billed_duration'];
echo $object['call_direction'];
echo $object['call_duration'];
echo $object['call_uuid'];
echo $object['end_time'];
echo $object['from_number'];
echo $object['initiation_time'];
echo $object['parent_call_uuid'];
echo $object['resource_uri'];
echo $object['to_number'];
echo $object['total_amount'];
echo $object['total_rate'];
}

Answer 2

First, to verify, if $array is the name of your array:
$response = $array["response"];
In the [meta] array, I need the [total_count] value
echo $response["meta"]["total_count"];
and for the [object] array, I'd like to get all the values to disaply them in a row (each object is a new row).
Use a foreach() function for all the objects:
foreach($response["objects"] as $object){
print_r($object);
}

You can use the "count" function with "COUNT_RECURSIVE" flag. It counts all the items inside the 'mixed' var. It counts parent element too.
count($array['objects'],COUNT_RECURSIVE);
example
$cibo = array(
'frutta' => array('arancia', 'banana', 'mela'),
'verdura' => array('carota', 'zucchina', 'piselli')
);
echo count($cibo,COUNT_RECURSIVE); // output 8
