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: ".$fie."");
        header("Content-Disposition: attachment; filename=\"".basename($filepath)."");
        header("Content-Transfer-Encoding: binary");
        header("Content-Length: ".@filesize($filepath));

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

上面的代码块运行但没有显示下载框，我试图下载的文件是jpeg文件，我已经设置了ob_start（）;在页面顶部，如果我删除ob_clean（）;从代码中，它向我显示下面的这个乱码

如果结肠后没有斜线，路径$scope.sryarndebitnote = [ { "_id": "57ac1b6d82e1c5940ac3c730", "user": { "_id": "57400c32bd07906c1308e2cf", "displayName": "mani selvam" }, "__v": 0, "created": "2016-08-11T06:30:05.118Z", "shipment_id": "57ac19b982e1c5940ac3c72f", "conversion_rate": "62.04", "invoice_value_fob_currency": "Rs", "invoice_value_fob": "300.231", "invoice_quantity_unit": "KG", "invoice_quantity": "37", "invoice_date": "2016-08-17", "supplier_name": "Msd", "buyer_name": "Mani selvam .R" }, { "_id": "57b5af69df0475401f644b2e", "user": { "_id": "57400c32bd07906c1308e2cf", "displayName": "mani selvam" }, "__v": 0, "created": "2016-08-18T12:51:53.671Z", "shipment_id": "57b5af5bdf0475401f644b2d", "conversion_rate": "62.06", "exclusive": true, "invoice_value_fob": "400.343", "invoice_quantity": "97", "supplier_name": "Msd", "buyer_name": "Mani selvam .R" },]看起来很奇怪？无论如何，在发送文件时，我总是使用如下，所以它可能会有用。

我有一个特别用于发送文件的功能，它是基本但可以工作，可以扩展到包括你在上面设置的其他标题。

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();
        }
    }
}
