Are there any specific PHP libraries or resources that can aid in developing a route planning application?

To develop a route planning application in PHP, you can utilize libraries like Graphp, which provides graph algorithms to calculate shortest paths between nodes. Additionally, you can use Google Maps API to access mapping and routing functionalities for displaying routes on a map. 

// Example code using Graphp library to calculate shortest path
use Graphp\Algorithms\ShortestPath\Dijkstra;
use Graphp\Graph\Graph;
use Graphp\Graph\Vertex;

$graph = new Graph();
$vertexA = $graph->createVertex('A');
$vertexB = $graph->createVertex('B');
$vertexC = $graph->createVertex('C');

$vertexA->createEdgeTo($vertexB)->setWeight(1);
$vertexB->createEdgeTo($vertexC)->setWeight(2);

$dijkstra = new Dijkstra($vertexA);
$shortestPath = $dijkstra->getVertexTarget($vertexC);

echo "Shortest path from A to C: ";
foreach ($shortestPath as $vertex) {
    echo $vertex->getId() . ' ';
}
