 $offsetKey = 25; //<---  offset seng mbok butohke

    //Lets do the code....
    $n = array_keys($myArrayInit); //<---- Grab all the keys of your actual array and put in another array
    $count = array_search($offsetKey, $n); //<--- Returns the position of the offset from this array using search
    $new_arr = array_slice($myArrayInit, 0, $count + 1, true);//<--- Slice it with the 0 index as start and position+1 as the length parameter.

Example 2: slice array php

array_slice() function is used to get selected part of an array.
Syntax:
array_slice(array, start, length, preserve)
*preserve = false (default)
If we put preserve=true then the key of value are same as original array.

Example (without preserve):
<?php
$a=array("red","green","blue","yellow","brown");
print_r(array_slice($a,1,2));
?>

Output:
Array ( [0] => green [1] => blue )
  
Example (with preserve):
<?php
$a=array("red","green","blue","yellow","brown");
print_r(array_slice($a,1,2,true));
?>

Output:
Array ( [1] => green [2] => blue )
