if you use php5 you may get it to work with wrappers.

If you use [man]fsockopen[/man] to set a HEAD request for the page (looks exactly like a GET request except you use HEAD instead of GET - an example of what a request looks like is on the manual page), you'll get just the headers. You can look through that to see if there's a Last-Modified: header - if there's one there it'll be the closest you'll get to the resource's "modification time".

Let's see the code you tried with, and maybe we can fix it.

Hai

here is the code

can you find the bug in this code and rectify it.

thankz

<?php
$URL = "www.sanposoft.com";
$fp = fsockopen ($URL, 80, $errno, $errstr, 30);

if (!$fp)
echo "$errstr ($errno)\n";
else {
fputs ($fp, "HEAD /syncrx/test/Test.php HTTP/1.0\r\n\r\n");
$match = array();
while (!feof($fp)) {
$line = fgets($fp, 2280);
echo "Hello" . $line . "<br>";
if (preg_match('/^{Last-Modified:} (.+)$/i', $line, $match))
break;
}
fclose ($fp);

if (count($match) > 0)
$date = $match[1];
else
$date = "UNKNOWN DATE";

// Note date time is in GMT, process further if you
// want local date time
echo $date . "\n";
}
?>

Reading the headers, I see the response is a 400 Bad Request. Presumably the request is bad.

fputs ($fp, "HEAD http://www.sanposoft.com/syncrx/test/Test.php HTTP/1.0\r\n\r\n");

Of course, if the server won't say when the resource was last modified, there's no way for you to find out. (And remember, it's a resource, and a resource doesn't have to be a file on the server.)
