Ok, The directory "VatsimPHPfiles" goes in your site root directory, it should only contain the .txt files. The file VatsimPHPgenerator.php also goes in your site root by itself, not in any directory.
Here is an example of how I use it.
<?php
require_once("VatsimPHPgenerator.php");
$VatsimPHP=new VatsimPHP;
$pilotlist=$VatsimPHP->airline("put your va's call letters here");
for($i = 0; $i < count($pilotlist); $i++)
{
echo '<p>';
echo $pilotlist[$i][0].':';
echo $pilotlist[$i][2];
echo '</p>';
}
if(count($pilotlist) == "0")
{
echo "<p>Currently no operations</p>";
}
?>
