Here, I have provided an example of implementing Google Directions. This should give you the confidence to try more out. I recommend that you visit http://code.google.com/apis/maps/documentation/directions/ for more options.
See demo.

<?php
$params = 'origin=Toddington,Bedfordshire';
$params .= '&destination=Cranfield,Bedfordshire';
$params .= '®ion=uk&sensor=false';
$data = json_decode(file_get_contents('http://maps.googleapis.com/maps/api/directions/json?'.$params));
if ($data->status === 'OK')
{
$route = $data->routes[0];
foreach ($route->legs as $leg)
{
foreach ($leg->steps as $step)
{
echo $step->html_instructions .'<br />';
}
}
}
