Modifying an existing scrip to grab this text:Solar Discussion. I am getting the text to here: solar-discussion.txt but not here: solar-discussion.php. The code is below. Can't figure out why its not reading the cached file.
Thanks for any help on this, Doug
Code:
<?php

// fetch it each time
$refetchSeconds = 1800; // refetch every nnnn seconds
// end of settings
// Constants
// don't change $fileName or script may break ;-)
$fileName = "http://www.swpc.noaa.gov/ftpdir/latest/RSGA.txt";
// end of constants
// ------ start of code -------
