 Posted: Tue Jun 27, 2006 1:12 am Post subject: php-gtk2 file grabber |
 |
|
This is the code to a basic file grabber program.
this is part of a larger program i am writing to apply updates and extentions to Gnope (windows) and php.
hope someone finds this code helpful contians some useful functions.
sec2hms() converts seconds to h:mm:ss format
remote_file_size ($url) gets file size of remote file
the base of this code is a progressbar example i found in the forum so this is more of a testing bed for the final code.
| Code: | <?php
function bytes_scale($bytes)
{
if ($bytes < 1024 )
return array($bytes,'B',$bytes);
elseif ($bytes >= 1024 && $bytes < 1048576 )
return array(round($bytes/1024, 2),'kB',$bytes);
elseif ($bytes >= 1048576 && $bytes < 1073741824 )
return array(round($bytes/1048576, 2),'MB',$bytes);
else
return array(round($bytes/1073741824, 2),'GB',$bytes);
}
function remote_file_size ($url)
{
$head = "";
$url_p = parse_url($url);
$host = $url_p["host"];
$path = $url_p["path"];
$fp = fsockopen($host, 80, $errno, $errstr, 20);
if(!$fp)
{ return false; }
else
{
fputs($fp, "HEAD ".$url." HTTP/1.1\r\n");
fputs($fp, "HOST: dummy\r\n");
fputs($fp, "Connection: close\r\n\r\n");
$headers = "";
while (!feof($fp)) {
$headers .= fgets ($fp, 128);
}
}
fclose ($fp);
$return = false;
$arr_headers = explode("\n", $headers);
foreach($arr_headers as $header) {
$s = "Content-Length: ";
if(substr(strtolower ($header), 0, strlen($s)) == strtolower($s)) {
$return = substr($header, strlen($s));
break;
}
}
return $return;
}
if(!class_exists('gtk'))
{
die("Please load the php-gtk2 module in your php.ini\r\n");

function quit_routine($dialog)
