Hey Drew, I used php to do almost this exact same thing. The error
checking in this could be a little tighter, but should do what you want.
Hope this helps...
Also if you are running a *nix you could set up a very simple cron wget.
Using the timestamping feature of "wget -N" (or something like that) to
compare dates, the program will only get the file if newer, otherwise
ignore.
If you have any other questions, feel free to email me on-list
or off-list.....
function get_web_page($my_url)
{
$fp = fopen($my_url, "r");
$page_data="";
while ($fp && !feof($fp))
$page_data .= fgets($fp,1000);
fclose($fp);
return $page_data;
}
function write_file_to_disk($my_file_name, $data)
{
if (!is_writeable($my_file_name))
{
print "Cannot write to file \"$my_file_name\"";
exit;
}
if (!$file_handle = fopen($my_file_name, "w+"))
{
print "Cannot open file \"$my_file_name\"";
exit;
}
if (!fwrite($file_handle, $data))
{
print "Cannot write to file \"$my_file_name\"";
exit;
}
fclose($file_handle);
}
