PHP array - `array_splice` issue - php

Question

I am working with PHP array to store the comma separated values of product Ids and then in turn use them to show as recent seen products.
Implementation is as below:
$product_data = array();
$array_ids_a_display = array();
$check_status = array();
$array_check= array();
$_COOKIE['Pr'] = [1,2,3,4,5,6,7,8]
Then i am Taking the last point of the stored string
$array_check = explode(',',substr($_COOKIE['IdProduto'],0,-1));
Now, i check of products are enabled then store them into one other array
foreach($array_check as $id_a_checar){
$check_status = $this->model->getProduct($id_a_checar);
if($check_status['status']){ // If status is 1
$array_ids_a_display[$contprods++] = $id_a_checar;
}
}
if($s['limit']>count($array_ids_a_display)){
//If the number of valid products < number of products of module
$s['limit'] = count($array_ids_a_display);
//will show,then reconfigures the number of products that will show
}
}
where $s['limit'] comes from backend , let us say 6 to limit the number of products.
Now, i will reverse the array to get latest visited product at first place like as
$last_ended = array_reverse($array_ids_a_display);
array_splice($last_ended,0,(int)$s['limit']);
foreach ($last_ended as $result) {
$product_data[$result] = $this->product->getProduct($result);
}
Now here comes the problem, as i am only getting 3 products in $product_data array but is shall get 6 products.
I hope that there is issue with array_splice because if i will comment array_splice then i am getting all stores products in cookies as result.
Mysql query is working very fine.
Please advice how to get latest 6 values from array

Answer 1

Here you are:
$last_ended = array(1, 2, 3, 4, 5, 6, 7, 8);
$last_ended = array_reverse($last_ended);
//here is what you missed:
$last_ended = array_splice($last_ended, 0, 6);
print_r($last_ended);
//returns Array ( [0] => 8 [1] => 7 [2] => 6 [3] => 5 [4] => 4 [5] => 3 )
You need to assign your $last_ended var into array_splice result.

Answer 2

<?php
// Get the last 6 entries of an array...
$arr = array(
1,
2,
3,
4,
5,
6,
7,
8
);
$entries = array_splice($arr, -6);
// returns [3, 4, 5, 6, 7, 8]
}

Answer 3

$maxResultLength = 6;
$someArray = [1,2,3,4,5,6,7,8,9,10,'a','b','c','d','e','f','g','h'];
$startIndex = (count($someArray) >= $maxResultLength) ? count($someArray) - $maxResultLength : 0;
$lastSixElements = array_slice($someArray, $startIndex, $maxResultLength);
or
$maxResultLength = 6;
$someArray = [1,2,3,4,5,6,7,8,9,10,'a','b','c','d','e','f','g','h'];
$lastSixElements = array_splice($someArray, -6);
