What are the best practices for handling and sorting arrays with thousands of entries in PHP?

When handling and sorting arrays with thousands of entries in PHP, it is important to use efficient sorting algorithms like quicksort or mergesort to avoid performance issues. Additionally, consider using array functions like array_multisort() for sorting multidimensional arrays and array_chunk() for splitting large arrays into smaller chunks for easier processing. 

// Example code snippet for sorting a large array using quicksort algorithm
function quicksort($array) {
    if (count($array) < 2) {
        return $array;
    }
    
    $pivot = $array[0];
    $left = $right = array();
    
    for ($i = 1; $i < count($array); $i++) {
        if ($array[$i] < $pivot) {
            $left[] = $array[$i];
        } else {
            $right[] = $array[$i];
        }
    }
    
    return array_merge(quicksort($left), array($pivot), quicksort($right));
}

$largeArray = // array with thousands of entries
$sortedArray = quicksort($largeArray);
