Answer 1

echo fread($file,filesize($file_dir.$file_name));
这块换成直接输出上面的$text

Answer 2

$file_dir = "./"; 
$file_name="status.txt";//$file=fopen($file_dir.$file_name,"r");
Header("Content-type: application/octet-stream");
Header("Accept-Ranges:bytes");
Header("Accept-Length:".filesize($file_dir.$file_name));
Header("Content-Disposition: attachment; filename=".$file_name);
//echo fread($file,filesize($file_dir.$file_name));
//fclose($file);
echo 'aaa';

Answer 3

$status = array(array('message'=>'hello'),array('message'=>'world'));
ob_start();
foreach($status as $s) {        
        $text = "{$s['message']}\r\n";
        echo $text;
}  
$content = ob_get_contents();
ob_end_clean();
$file_name = "status.txt";
Header("Content-type: application/octet-stream");
Header("Accept-Ranges:bytes");
Header("Accept-Length:".strlen($content));
Header("Content-Disposition: attachment; filename=".$file_name);
echo $content; 

Answer 4

那前面那些Header()该怎么写呢？文件大小是不确定的呀？
