Hi,
I am trying to build a page where i pull out a number of reviews about
places to go from a database, each containing a postcode..
Now i am using Googles Directions API ad have written some code which
should pull out the distance in miles from XML.
See my code below:
class PostcodeSearch{
public function LoadXml($origin, $destination){
$xml = simplexml_load_file("http://maps.google.com/maps/api/
directions/xml?origin=".$origin."&destination=".
$destination."&sensor=false");
foreach ($xml->xpath('//distance') as $distance):
$lastvalue = $distance->value;
endforeach;
$total = $lastvalue * 0.00062137119;
$total = number_format($total, 2);
return $total;
}
}
And then i putt the code out like this:
<?
while($row = mysql_fetch_array($review)){
$text = strip_tags($row['body']);
$intro = substr($text, 0, 600);
$pcode = PostcodeSearch::LoadXML($_GET['search'],
$row['postcode']);
?>
Distance is <?=$pcode?> miles.
<? } ?>
The results should be shown on this page:
http://babiesinthecity.co.uk/test/?searchbutton=&search=M25
But notice i get errors, can someone please help me out?
A typical XML file which contains results is as such:
http://maps.google.com/maps/api/directions/xml?origin=m25%202Nu&destination=M25%202SW&sensor=false
Any ideas what i'm doing wrong?
Thanks
Kind regards
billy
