Question

foreach ($idsonly as $key=>$price) {  

    if($curencyarray[$key]=="Internet Download"){

        $dfr = $productidarray[$key].'.'.$itemformatarray[$key];
        $file = 'C:wamp/www/allcars/Dhotois/'.$bigidarray[$key].'/'.$dfr;
        $fie = str_replace("; charset=binary","",$mimeformarray[$key]);
        $filename = $dfr;
        $filepath = "C:wamp/www/allcars/Dhotois/".$bigidarray[$key]."/" . $filename;

        set_time_limit(0);
        ignore_user_abort(false);

        ini_set('output_buffering', 0);
        ini_set('zlib.output_compression', 0);

        header("Content-Description: File Transfer");
        header("Pragma: public");
        header("Expires: 0");
        header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
        header("Cache-Control: private",false);
        header("Content-Type: ".$fie."");

        header("Content-Transfer-Encoding: binary");
        header("Content-Length: ".@filesize($filepath));

        set_time_limit(0);
        @readfile("$filepath") or die("File not found.");
        ob_clean();
    }
}

The above block of code runs but does not display the download box, the file i am trying to download is a jpeg file, i already set ob_start(); at the top of the page and if i remove the ob_clean(); from the code, it shows me this gibberish below

please, what could possibly be wrong with my code?, any help and i will be so grateful.

Answer 1

The path C:wamp/www looks peculiar, should there not be a slash after the colon? Anyway, when sending files I have always used as below so perhaps it will be useful.

foreach ($idsonly as $key=>$price) {  

    if($curencyarray[$key]=="Internet Download"){

        $dfr = $productidarray[$key].'.'.$itemformatarray[$key];
        $file = 'C:/wamp/www/allcars/Dhotois/'.$bigidarray[$key].'/'.$dfr;
        $fie = str_replace("; charset=binary","",$mimeformarray[$key]);
        $filename = $dfr;
        $filepath = "C:/wamp/www/allcars/Dhotois/".$bigidarray[$key]."/" . $filename;

        if( realpath( $filepath ) ){

            set_time_limit(0);
            ignore_user_abort(false);

            ini_set('output_buffering', 0);
            ini_set('zlib.output_compression', 0);

            header("Content-Description: File Transfer");
            header("Pragma: public");
            header("Expires: 0");
            header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
            header("Cache-Control: private",false);
            header("Content-Type: ".$fie."");
            header("Content-Disposition: attachment; filename=".basename($filepath));
            header("Content-Transfer-Encoding: binary");
            header("Content-Length: ".@filesize($filepath));

            set_time_limit(0);

            /* send the file piece by piece */
            if( $file = fopen( $filepath, 'rb' ) ) {
                while( !feof( $file ) and ( connection_status()==0 ) ) {
                    print( fread( $file, 1024*8 ) );
                    flush();
                }
                fclose( $file );
            }
            ob_clean();
        }
    }
}

I have a function especially for sending files, it's basic but works and can be extended to include the other headers you set above.

function sendfile( $filename, $filepath ) {
    if( file_exists( $filepath ) ) {

        if( !is_file( $filepath ) or connection_status()!=0 ) { return FALSE;   }

        header("Cache-Control: no-store, no-cache, must-revalidate");
        header("Cache-Control: post-check=0, pre-check=0", false);
        header("Pragma: no-cache");
        header("Expires: ".gmdate("D, d M Y H:i:s", mktime(date("H")+2, date("i"), date("s"), date("m"), date("d"), date("Y")))." GMT");
        header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT");
        header("Content-Type: application/octet-stream");
        header("Content-Length: ".(string)( filesize( $filepath ) ) );
        header("Content-Disposition: inline; filename={$filename}");
        header("Content-Transfer-Encoding: binary
");


        if( $file = fopen( $filepath, 'rb' ) ) {
            while( !feof( $file ) and ( connection_status()==0 ) ) {
                print( fread( $file, 1024*8 ) );
                flush();
            }
            fclose( $file );
        }

        clearstatcache();
        return( ( connection_status()==0 ) and !connection_aborted() );
    }
}


$result=sendfile('mypicture.jpg','c:/wwwroot/images/banana.jpg');
