What are common pitfalls when implementing the Kruskal Algorithm in PHP?

One common pitfall when implementing the Kruskal Algorithm in PHP is not properly sorting the edges before processing them. To avoid this issue, ensure that the edges are sorted in non-decreasing order based on their weights before applying the algorithm. 

// Sort the edges in non-decreasing order based on their weights
usort($edges, function($a, $b) {
    return $a['weight'] - $b['weight'];
});
