PHP實現簡單的檔案下載通用方法

function download_file($file){ if(is_file($file)){ $length = filesize($file); $type = mime_content_type($file); $showname = ltrim(strrchr($file,'/'),'/'); header("Content-Description: File Transfer"); header('Content-type: ' . $type); header('Content-Length:' . $length); if (preg_match('/MSIE/', $_SERVER['HTTP_USER_AGENT'])) { //for IE header('Content-Disposition: attachment; filename="' . rawurlencode($showname) . '"'); } else { header('Content-Disposition: attachment; filename="' . $showname . '"'); } readfile($file); exit; } else { exit('檔案已被刪除！'); } } 複製代碼
