How to get the name of cities using neo4j and PHP?

Question

I followed this tutorial to do the following:

    echo "<h2>Encontre a rota mais curta da cidade A para a cidade B</h2>";

    $query4 = 'MATCH p = (a {name: \'Palo Alto\'})-[r*2..5]->(b {name: \'Santa Clara\'}) WHERE NOT(a-->b) WITH p.name, relationships(p.name) AS rcoll RETURN a.name, b.name, p.name, reduce(totalDistance=0, x IN rcoll| totalDistance + x.distance) AS totalDistance ORDER BY totalDistance LIMIT 5';  

    $result4 = $client->run($query4);

    $record4 = $result4->getRecord();

    echo '<b>' . $record4->get('a.name') . '</b>';

    foreach ($result4->getRecords() as $records4) 
    {
      echo ' ⇢ ' . $records4->get('p.name');
    }

    echo '<b>' . $record4->get('b.name') . '</b>';

I tried the name of the cities, using the p.name of MATCH p.

Similar to $query4 = 'MATCH (a {name: \'Palo Alto\'})-[r*2..5]->(p) RETURN a.name, p.name LIMIT 5'; that worked, only that wanted to catch the city of Palo Alto to Santa Clara using the shortest route and the total distance because this result gave from Palo Alto to Milpitas for lack of shorter route and total distance.
