In the context of pathfinding in PHP, what role does the "vertex" play and how can it be utilized?

In pathfinding in PHP, a "vertex" represents a point or node in a graph or network. It plays a crucial role in determining the connections between different points and calculating the shortest path. To utilize vertices in pathfinding, you can create a graph data structure with vertices representing points of interest and edges representing connections between them. By implementing algorithms like Dijkstra's or A* on this graph, you can find the shortest path between two vertices. 

class Vertex {
    public $name;
    public $neighbors;

    public function __construct($name) {
        $this->name = $name;
        $this->neighbors = [];
    }

    public function addNeighbor($neighbor, $weight) {
        $this->neighbors[$neighbor] = $weight;
    }
}

// Example usage
$vertexA = new Vertex('A');
$vertexB = new Vertex('B');
$vertexC = new Vertex('C');

$vertexA->addNeighbor($vertexB, 5);
$vertexA->addNeighbor($vertexC, 10);

// Implement pathfinding algorithms on this graph
