[Alex_isback]

Hello everyone

I use Curl and php 7, is it possible while unloading data view only last result and delete the previous ones (ob_flush())?

for ($i=0;$i<count($str[1]);$i++) {
			//echo "\rScaricamento in corso... [Pagina#".
			($z+1)."/".$pages." - Foto#".(++$u)."/".$pagesnum[1]."]";
			if (!file_exists($folder.'_'.$u.'_'.$images.'.jpg')) 
            file_put_contents($folder.'_'.$u.'_'.$images.'.jpg', get('https://m.media-amazon.com/images/M/'.$str[1][$i].$str[2][$i].'jpg'));

You can't echo something, have it displayed, then remove it.  Once the content has been sent to the browser for display it's there.

Trying to stream content as a progress indicator is already questionable.  It may or may not working depending on what kind of software / buffers are involved in the connection.

If you want to progress indication then the ideal thing to do would be to run your tasks as background requests using fetch() and update a display with the progress information as they complete.
