回复讨论(解决方案)
加个下载类型试试 header("content-type: image/png");
同1#
header("Content-Dispostion: attachment;filename=". $file_name);
这个是带路径的了吧
header("Content-Dispostion: attachment;filename=". basename($file_name));
这样才行
谢谢三位 你们说的 都对
1?和2??位。。。
加header("content-type: image/png"); ?有用的,因?是下?,不是?示?片。
首先,你的code根本就不能?行,有????了。
@$file_name=iconv(" utf_8","gb2312",$file_name); ??是UTF-8
while(!feof( $file_path)){ ??是$fp
header("Content- Dispostion: attachment;filename=".$file_name); ??是 disposition
改成??就可以了。
function down_file($file_name,$file_path){ @$file_name=iconv("utf-8","gb2312",$file_name); $file_path=$_SERVER['DOCUMENT_ROOT'].$file_path.$file_name; if(!file_exists($file_path)){ echo "文件不存在"; return; } $fp=fopen($file_path,"r+"); $file_size=filesize($file_path); header("Content-type: application/octet-stream"); header("Accept-Rangers: bytes"); header("Accept-Length: $file_size"); header("Content-Disposition: attachment;filename=".$file_name); while(!feof($fp)){ $data=fread($fp,1024); echo $data; } fclose($fp);}down_file("php.png","/down/");
