PHP做下載檔案的方法

<?phpheader("Content-Type: application/force-download");header("Content-Disposition: attachment; filename=ins.jpg"); readfile("imgs/test_Zoom.jpg");?>

 

第一行代碼是強制下載；

第二行代碼是給下載的內容指定一個名字；

第三行代碼是把下載的內容讀進檔案中。

 

Example #1 Forcing a download using readfile()

 

<?php$file = 'monkey.gif';if (file_exists($file)) {    header('Content-Description: File Transfer');    header('Content-Type: application/octet-stream');    header('Content-Disposition: attachment; filename='.basename($file));    header('Content-Transfer-Encoding: binary');    header('Expires: 0');    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');    header('Pragma: public');    header('Content-Length: ' . filesize($file));    ob_clean();    flush();    readfile($file);    exit;}?>
