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。
