本文实例讲述了php隐藏实际地址的文件下载方法。分享给大家供大家参考。具体如下:
下面这段php代码可不透露实际的文件下载地址。
function download_document($filename,$path="",$mimetype="application/octet-stream"){ header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Disposition: attachment; filename = $filename"); header("Content-Length: " . filesize($pathto . $filename)); header("Content-Type: $mimetype"); echo file_get_contents($pathto . $filename);}实现方法二:
<?php$file = "1.txt";// 文件的真实地址(支持url,不过不建议用url)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;}?>希望本文所述对大家的php程序设计有所帮助。
