PHP: Saving files with PHP to different root directory?

Question

OK when I save uploaded files with PHP via move_uploaded_file() I cannot use an absolute URL I have to use a relative one. My site has 2 root directories one for the http side and one for the https side: httpdocs and httpsdocs respectively. So if my script is on the https side how can I save the file to a location on the http side?

Thanks!

UPDATE OK so it seems like I am using the wrong absolute path convention I am doing it like this:

$dir = 'https://www.mydomain.com/masonic_images/';
move_uploaded_file($_FILES['blue_image']['tmp_name'], $dir.$new_name);

Answer 1

move_uploaded_file() doesn't accept URLs for either parameter. The destination is an absolute path on your filesystem.

<?php
$dir = '/var/www/httpsdocs/'; // Adjust to your configuration
move_uploaded_file($_FILES['blue_image']['tmp_name'], $dir.$new_name);

As @ apphacker suggested. you can use realpath(__FILE__) to determine the absolute path to a file.

Answer 2

如果由于不知道绝对路径而不能使用绝对路径，请使用PHP的realpath（）找出它是什么，然后使用它。

Answer 3

Are the httpdocs and httpsdocs directories both located in the same parent folder? If so, just use a relative path for the second parameter in move_uploaded_file to place the file in the other root directory.

For example:

$uploaddir = '../httpdocs/';
$uploadfile = $uploaddir . basename($_FILES['myfile']['name']);

This code assumes that the uploading script is located in the httpsdocs root directory, and that you want to save the file into the httpdocs directory.

Answer 4

请注意，由于您将上传的文件放在httpdocs因此可以上传php文件并执行任意代码。
