replace value in php array with given index

I have a problem on replacing a value in array with exact given index. To be exact, I'd like to replace a string in array[2] with a new number but I don't have an idea. So please have a look on my resources :

pos:0 //position of index in array 
id:498 //id of a field
new:6300 //new value to replace in an array
cost:6200-5200-4600-5600-4100 //the array

From above, I'd like to replace a string indexes "0" in "cost" with a new string from "new" so the expected result should be :

6300-5200-4600-5600-4100

I tried to search for everywhere but there's nothing return but array_search - which is not what i'm looking for. Please advise.

It's so simple:

<?php

$array = array(
    6200, 
    5200, 
    4600, 
    5600, 
    4100
);

$pos = 0;
$new = 6300;

$array[$pos] = $new;

?>

Try this:

$the_array[$pos] = $new

$pos = 0;                            // position
$new = 6300;                         // new value
$cost = '6200-5200-4600-5600-4100';  // string
$cost = explode('-', $cost);         // make it array
$cost[$pos] = $new;                  // change the position $pos with $new
$cost = implode('-', $cost);         // return new $cost
// 6300-5200-4600-5600-4100
