I wasn't able to reproduce your problem using your function with either
a local file, an file from an ftp server or from an http site. If the
problem still exists with a current snapshot please give more
information what kind of file you're trying to transfer and a gdb
backtrace. Thanks.

The following function also gives a error

***
function upload_file_from_url($filename, $url, $dir = 'transfer/docs/',
$overwrite_uid = false)

Reproduce code:
---------------
function upload_file_from_url($filename, $url, $dir = 'transfer/docs/',
$overwrite_uid = false)
{
//ver. 2.0
//error_reporting(E_ALL);
if($fp = fopen($url,"rb")) //file exists
{
logmsg ("DEBUG:UPLOAD - open remote file.");
//generate UNQ name
$filename = $filename;
$filetype = 'application/octet-stream';
$fileinfo = pathinfo($filename);
$fname = $fileinfo['filename'];
$filedata = '';
logmsg ("DEBUG:UPLOAD - read remote file.");
while (!feof($fp)) {
$filedata .= fread($fp, 8192);
}
if(!$filedata)
{
fclose($fp);
return false;
}
logmsg ("DEBUG:UPLOAD - reading done!");
logmsg ("DEBUG:UPLOAD - check file size");
$filesize = strlen($filedata);
if($filesize == 0)
{
fclose($fp);
return false;
}
logmsg ("DEBUG:UPLOAD - size is ok:{$filesize}");
logmsg ("DEBUG:UPLOAD - check existance of filename");
//check file exists
$exists = true;
$i = 0;
while(file_exists($this->web_root.$dir.$fname.'.'.$fileinfo['extension']))
{
$i++;
$fname.= '-'.$i;
}
$filepath = $fname.'.'.$fileinfo['extension'];
logmsg ("DEBUG:UPLOAD - check name done. using - ".$filepath);
logmsg ("DEBUG:UPLOAD - copy data..");
//store file
$fpl = fopen($this->web_root.$dir.$filepath,"w");
if($fpl)
{
fwrite($fpl,$filedata,$filesize);
fclose($fpl);
}
else
{
fclose($fp);
return false;
}
fclose($fp);
logmsg ("DEBUG:UPLOAD - data copied - done.");
return array('name' => $filename,'size'=>$filesize, 'path'=>
$filepath);
}
else
{
return false;
}
}
Expected result:
----------------
download files from website , store and return array
