The filereading hint was a good suggestion- it does actually seem to
work if I'm using file_get_contents instead of join('',file($file))-
could smdb. explain why?

Kindly,
Andi

I'm sorry. The function where the file is written is obviously not
download, but this one:

function saveHTTPcache($url,$resp){
  $cfile='cache/imdb/'.md5($url);
  $string=serialize($resp);
  @fwrite(@fopen("$cfile", "w"),$string,strlen($string));
}

Have not tried the snapshot yet- is it supposed to fix (un)serialize or
load/store?

This is the code to save and restore the data:

function download($url, $local){
  $resp = fetchHTTP($url);
	$writefile = @fopen($local, "wb");
	if(!$writefile) return false;
	if(!fwrite($writefile, $resp[data], strlen($resp[data]))) return
false;
	fclose($writefile);
	return true;
}

function getHTTPcache($url){
  $cfile='../videodb/cache/imdb/'.md5($url);
    $resp = unserialize(join('',file($cfile)));
    return $resp;
}

The problem doesn't have to do anything with serialize/unserialize but
with the way you store/load the serialized data. Can you tell us how?
And do you do any manual changes to the serialized data or even view it
with an external editor?
