Opening Google Map at Last Destination.

[ijyoung]

I have code driven by php that tracks co-ordinates on Google Map and
has a different icon on the last co-ordinate entered. I would like the
map to open at this co-rodinate rather than the first one. Any
thoughts on how we could achieve this?

Code is as follows

[code]
<?php
function makePlacemark($line,$id)
{
// 38 degrees 22.3 N 020 degrees 42.8 E anchorage in
Ithaca 7/7/09
$t = preg_split("/[\s]+/",$line);
$north = $t[0] + $t[2]/60;
if ($t[3] == "S") $north = $north * -1;
$east = $t[4] + $t[6]/60;
if ($t[7] == "W") $east = $east * -1;
$description = "";
for ($pos = 8; $pos < count($t); $pos++)
{
$description = $description . " " . $t[$pos];
}
$pm = "
<Placemark>
<name>$description</name>
<description> </description>
<styleUrl>#$id</styleUrl>
<Point><coordinates>$east,$north,0</coordinates></Point>
</Placemark>
";
return $pm;
}

function readPlacemarks($file, $delimiter="\n\r")
{
$fp = fopen( $file, 'r' );
$placemarks = '';
$line = fgets($fp);
while ( !feof ( $fp) )
{
$placemarks = $placemarks . makePlacemark($line,"standardMark");
$line = fgets($fp);
}
$placemarks = $placemarks . makePlacemark($line,"lastMark");
return $placemarks;

}
