How can you extract specific values like name, GPS coordinates, and elevation from a GPX file using PHP?

To extract specific values like name, GPS coordinates, and elevation from a GPX file using PHP, you can use a library like SimpleXML to parse the XML structure of the GPX file. You can then access the specific elements you need by traversing the XML tree and extracting the desired values. 

<?php

// Load the GPX file
$xml = simplexml_load_file('path/to/your/file.gpx');

// Extract name
$name = $xml->metadata->name;

// Extract GPS coordinates and elevation
foreach ($xml->trk->trkseg->trkpt as $point) {
    $lat = $point['lat'];
    $lon = $point['lon'];
    $elevation = $point->ele;
    
    // Do something with the extracted values
    echo "Name: $name, Latitude: $lat, Longitude: $lon, Elevation: $elevation\n";
}

?>
