PHP強制下載的問題
$file_dir = 'd:/file/';
$file_name = 'XXX.zip';
$file=fopen($file_dir.$file_name,"r");?
header("Content-Type: application/force-download");
header("Accept-Ranges: bytes");
header("Accept-Length: ".filesize($file_dir.$file_name));
header("Content-Disposition: attachment; filename=".$file_name);
// 輸出文件內(nèi)容
echo fread($file,filesize($file_dir.$file_name));
fclose($file);
exit;
為什么我這樣寫了之后運行他沒有直接強制下載這個文件，反而讀取了這個文件？？
------解決方案--------------------
你最好不要用fread($file,filesize($file_dir.$file_name));
你把
echo fread($file,filesize($file_dir.$file_name));
fclose($file);
換成
readfile($file_dir.$file_name);
試試
最好再添加以下兩句
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Pragma: no-cache");
這樣應該可以解決你的問題
