How to add new array item into existing array?

Question

I want to add new array item to an existing array. I'm using array_push for this purpose but it is not working.

Array

Array ( [productID] => 51  )

Php Code

if(isset($_REQUEST['sendProductId'])){

    $inserted = $_COOKIE['productID'];
    $original = $_REQUEST['sendProductId'];

    if($inserted){
        $cookie_value   =   array_push( $inserted, $original ); 
    }else{
        $cookie_value = $_REQUEST['sendProductId'];
    }
    $cookie_name = 'productID';

    setcookie($cookie_name, $cookie_value, time() + (86400 * 30));

}
print_r($_COOKIE);

Actually I want to add products ids into a cookie. I have also used array_splice for this but it's also not working.

Please guide me where I'm going wrong.

@Semmix I think it is not duplicate because my question is totally different from above mention link — Ayaz Ali Shah, Dec 07 '15 at 14:23
What is in `var_dump( $inserted);` ,`var_dump( $original);` ? — ashkufaraz, Dec 07 '15 at 14:26
@ashkufaraz `string '51' (length=2)` is result of this `var_dump( $inserted);` — Ayaz Ali Shah, Dec 07 '15 at 14:31
@ashkufaraz it does not giving any result because when i post data through ajax then its showing the value — Ayaz Ali Shah, Dec 07 '15 at 14:35
Reading the [manual](http://php.net/array_push) would show you that you are using array_push() incorrectly. — vascowhite, Dec 07 '15 at 14:38
You want set `productID=>51` and `productID=>52` in cookie ? — ashkufaraz, Dec 07 '15 at 14:52
`setcookie("TestCookie", $value);` `$value` is not array http://php.net/manual/en/function.setcookie.php — ashkufaraz, Dec 07 '15 at 14:57

With serialize(array()) set array to cookie and for read data use $data = unserialize($_COOKIE[$cookie_name]);

so try this

if(isset($_REQUEST['sendProductId'])){

    $inserted = 51;//$_COOKIE['productID'];
    $original = 52;//$_REQUEST['sendProductId'];

    $cookie_name = 'productID';

    $cookie_value[0]   = $original;   
    if($inserted)
        $cookie_value[1]   = $inserted;   



    setcookie($cookie_name, serialize($cookie_value), time() + (86400 * 30));

}

$data = unserialize($_COOKIE[$cookie_name]);
array(2) {
  [0]=>
  int(52)
  [1]=>
  int(51)
}

From the documentation for array_push():

array_push — Push one or more elements onto the end of array
int array_push ( array &$array , mixed $value1 [, mixed $... ] )
array_push() treats array as a stack, and pushes the passed variables onto the end of array. The length of array increases by the number of variables pushed. Has the same effect as:
<?php
$array[] = $var;
?>
repeated for each passed value.
