Please convert this code from php to vb6?
Greetings? hope all active user on this forum is fine :)
i was looking for code to get web file size correctly. After a lot research i don't find any vb6 code that does this correctly on most files but found a php code.
Php code works on good on my server. But i don't want to use php code, i need vb6 code..
so, if any one can convert following code to pure vb6, then it would be great
here is the php code:
Code:
function remote_file_size($url){
$head = "";
$url_p = parse_url($url);
$host = $url_p["host"];
if(!preg_match("/[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*/",$host)){
$ip=gethostbyname($host);
if(!preg_match("/[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*/",$ip)){
return -1;
}
}
if(isset($url_p["port"]))
$port = intval($url_p["port"]);
else
$port = 80;
if(!$port) $port=80;
$path = $url_p["path"];
$fp = fsockopen($host, $port, $errno, $errstr, 20);
if(!$fp) {
return false;
} else {
fputs($fp, "HEAD " . $url . " HTTP/1.1\r\n");
fputs($fp, "HOST: " . $host . "\r\n");
fputs($fp, "User-Agent: http://www.example.com/my_application\r\n");
fputs($fp, "Connection: close\r\n\r\n");
$headers = "";
while (!feof($fp)) {
$headers .= fgets ($fp, 128);
}
}
fclose ($fp);
$return = -2;
$arr_headers = explode("\n", $headers);
foreach($arr_headers as $header) {
$s1 = "HTTP/1.1";
$s2 = "Content-Length: ";
$s3 = "Location: ";
if(substr(strtolower ($header), 0, strlen($s1)) == strtolower($s1)) $status = substr($header, strlen($s1));
if(substr(strtolower ($header), 0, strlen($s2)) == strtolower($s2)) $size = substr($header, strlen($s2));
if(substr(strtolower ($header), 0, strlen($s3)) == strtolower($s3)) $newurl = substr($header, strlen($s3));
}
if(intval($size) > 0) {
$return=intval($size);
} else {
$return=$status;
}
if (intval($status)==302 && strlen($newurl) > 0) {
$return = remote_file_size($newurl);
}
return $return;
}
any help would be highly appreciated..
thanks in advance..
best regards
