How to get array subset in PHP

Answer 1

function getSubset($array, $startIndex, $length) {
    // Extract a subset of the array
    return array_slice($array, $startIndex, $length);
}

$arr = [3, 7, 9, 0, 4, 2, 1, 8];
$startIndex = 2; // Start index for the subset
$length = 4;     // Number of elements in the subset

$subset = getSubset($arr, $startIndex, $length);

echo "Subset: " . implode(", ", $subset) . PHP_EOL;


  
/*
run:
      
Subset: 9, 0, 4, 2
