I use PHP 4.3.10 opendir() function to open directory from a given path...
I want to use the relative path:
$path = "/images/contents";...
@opendir($path);But it says the path is not accessible...
But when I use:
$path = $_SERVER[DOCUMENT_ROOT]."/images/contents";it works fine...
Why am I not able to use a relative path???
The dir structure is:
root
->images
-->contents
...
Help!
Thanks.
here remove the first "/"
$path = "images/contents";
if you echo out the $_SERVER['DOCUMENT_ROOT'] you will see its something like /home/username/public_html depending on the setup. php is able to access anything on the server so its paths begin from the root drive (think of it like C:\ on windows) and the webserver has a base path (which is your document root) so html code uses this document root, where php uses the server root
The script which is executing the opendir() is located in:
root->admin->test->browser->browser.php
echo $_SERVER['DOCUMENT_ROOT'];gives me:
D:\Milan\Posao\DRI\Website
which is actually the position of the root...
How can I use the URL path instead of this directory path?
keep using $_SERVER['DOCUMENT_ROOT']. thats the only way, or dont use a / in front
Well, currently I'm building a website and testing it locally... Within the website, I'm building an image gallery browser with preview and upload fuinctions.
If I use $_SERVER[DOCUMENT_ROOT], the image link includes:
"D:/Milan/Posao/DRI/Website" and the browser complains:
"D: is not a valid protocol..."
Filepaths starting with '/' are absolute, not relative.
Filepaths and URL paths are not the same thing.
OK,
does the ABSOLUTE PATH "/..." mean that it is relative to site root or what???
Why can't I use "/images" instead of "$_SERVER[DOCUMENT_ROOT]."images""???
/images refers to
D:/images <- doesnt exist
$_SERVER['DOCUMENT_ROOT]' . "/images" refers to
D:/Milan/Posao/DRI/Website/images <- correct
this is only what you use in php. for html you do use /images
