Can you Preserve Key Order While Sorting Associative Arrays in PHP?

Preserving Key Order During Sorting with PHP's uasort

Query:

Is it possible to sort the values of an associative array in PHP while maintaining the original order of keys, using PHP's built-in sorting functions?

Challenge:

To achieve a stable sort where equal values retain their initial key order, a custom sorting function must be employed since PHP does not support stable sorting natively.

Solution:

A custom merge sort, which guarantees O(n*log(n)) complexity and maintains stability, can be used:

<code class="php">function mergesort(&$array, $cmp_function = 'strcmp') {
    // Handle base cases
    if (count($array) <p><strong>Alternative Resource:</strong></p>
