嵌套数组中的访问元素PHP - 数组到字符串转换错误

Question

I need have an array structured like so

Array
 (
    [id] => 
    [name] => 
    [description] => 
    [table_id] => 
    [records] => Array
        (
            [0] => Array
                (
                    [id] => 
                    [table_id] => 
                    [created] => 2016-01-15T09:19:36-0700
                    [updated] => 
                    [created_by] => 
                    [updated_by] => 
                    [fields] => Array
                        (
                            [created] => 
                            [Delivery Date] => 
                            [Total Price Including Shipping] =>
                            [Enquiry Status] => 
                            [Equipment Booked 1] =>
                            [Equipment Booked 2] => 
                            [Equipment Booked 3] => 
                            [Equipment Booked 4] => 
                            [Equipment Booked 5] =>
                            [Equipment Booked 6] =>
                            [Surname] => 
                        )

                )

        )

    [record_count] => 1
)

I need to extract the [created] field from the last element of the nested array in [records]. I've tried doing the following

$target_elems = $target.['record_count'];
//print_r($target_elems);

//echo $target_elems;
//echo $target.['records'].[$target_elems].['created'];
echo '<pre>'; print_r($target); echo '<pre/>';

bur I always get Array to String conversion error (commented lines have been tested obviously).

the only generated output is

ArrayArrayArrayArray

As you said:- I need to extract the [created] field from the last element of the nested array in [records].

first count the number of records in records sub-array and then get the data:-

<?php
  $count = count($target['records']); // count number of record in records sub-array
  echo $target['records'][$count-1]['created']; // get last created from records array
?>
