Question

How to sort the part of an array in PHP

Answer 1

$arr = [15, 6, 19, 8, 3, 7, 9, 1, 4];

// Extract and sort the subarray from index 2 to 6
$subarray = array_slice($arr, 2, 5); // indices 2 to 6 → length 5
sort($subarray); // ascending sort

// Replace the original portion with the sorted subarray
array_splice($arr, 2, 5, $subarray);

// Print the updated array
foreach ($arr as $value) {
    echo $value . " ";
}
