Here's a handy little function to get file modification time of remote file (benquinn code
expanded basically), returns false if date-modified is not returned in the header:
function fileStamp($domain, $file)
{
$file = "/" . $file;
$fp = fsockopen ($domain, 80, $errno, $errstr, 30);
$header = "HEAD $file HTTP/1.0\r\nHost: $domain\r\n\r\n";
if (!$fp){
echo "$errstr ($errno)";
return false;
}
fputs ($fp, $header);
while (!feof($fp)) {
$output .= fgets ($fp,128);
}
fclose ($fp);
$begin = strpos($output, "Last-Modified: ") + 15;
if($begin==15) //no last-modified (like yahoo.com)
return false;
$end = strpos($output, "\n", $begin);
$time = substr($output, $begin, $end-$begin-1);
return strtotime($time);
}
