foreach($data as $directions){
    echo 'Start: '.$directions->route->leg->step->start_location->lat.' <br>End: '.$directions->route->leg->step->end_location->lng.'<br>

Try this after

if(!$data=simplexml_load_file("http://maps.googleapis.com/maps/api/directions/xml?origin=51.519812,-0.200774&destination=51.26246,-1.084024&sensor=false")){    trigger_error('Error reading XML file',E_USER_ERROR);}

Use this...

$start = $data->route->leg->step->start_location->lat;
$end = $data->route->leg->step->end_location->lng;
$html = $data->route->leg->step->html_instructions;
$distance = $data->route->leg->step->distance->text;
echo "Start: ".$start."<br />";
echo "End: ".$end."<br />";
echo "HTML: ".$html."<br />";
echo "Distance: ".$distance."<br />";

Let me add a little more.  I think what you are doing is trying to extract all of the "steps" in the XML.  Since there are many steps, you are trying to extract each step.  Try looking at the PHP example: http://www.php.net/manual/en/simplexmlelement.children.php

 

My example only takes the first child with the name of step.
