Use fsockopen() or fopen() (if remote open is enabled in php conf). Read the incoming buffer and count the length.
| Code: | $string = "";
$fp = fsockopen("http://foo.bar", 80, $errno, $errstr, 15);
if ($fp) {
fputs($fp, "GET images/image.gif HTTP/1.0\r\n");
fputs($fp, "HOST: http://foo.bar\r\n\r\n");
while(!feof($fp)) {
$pagetext = fgets($fp,300);
$string .= chop($pagetext);
}
fputs($fp,"Connection: close\r\n\r\n");
fclose($fp);
}
echo "Image size is " . strlen($string) ."bytes\n"; |
If you know PHP, you know what I mean. |
