php讀取csv實現csv檔案下載功能

 用PHP代碼下載CSV檔案，可以是字串，也可以是一個CSV檔案,下面直接上代碼

第一段是讀檔案，下載。第二段是字串下載。 代碼如下:<?php$fileName = "prefs.csv";header('Content-Type: application/octet-stream');header('Content-Disposition: attachment; filename=' . $fileName);header('Content-Transfer-Encoding: binary');header('Content-Length: ' . filesize($fileName));readfile($fileName); 代碼如下:<?php$fileName = "pref_" . date("YmdHis") . ".csv";header('Content-Type: application/octet-stream');header('Content-Disposition: attachment; filename=' . $fileName);echo $csv;
