how can i access a folder or file in parent folder php

i want a shared folder which contains ima开发者_Go百科ges to be accessed by html pages inside sub folders.(child folders)

If you mean your html folder and images folder are siblings, you're probably looking for the .. directory... um, thingy.

Your files look like:

/www
    /html
        index.php
    /images
        myimage.png

Write an img tag like this:

<img src="../images/myimage.png" />

Make a folder inside your website and put images into it.

Basically, there are two ways of linking to a resource (page/script/image/whatever):

• Use an absolute link: http://www.yourserver.com/path/to/resource.jpg
• Use a relative link: for example, to go from http://www.yourserver.com/path/from/page.html to http://www.yourserver.com/path/to/resource.jpg, you use ../to/resource.jpg

So just put your images on a publicly accessibly folder, and refer to them using one of those two methods.

Or refine your question :)

If I got it right, you have a folder with many folders inside, and inside does many folder you have html pages, and you want does pages to access the first folder...

main_folder

pic.png

pic.gif

pic.jpg

sub_folder

html_page.php

just use ../pic.png when you call the image file from the html_page.php

Was this what you where looking for ?

You can get the directory of the current file with the dirname funciton:

dirname(__FILE__)

If you want the parent directory you can use '..' thus:

$current_dir = dirname(__FILE__);
$parent_dir = $current_dir.'/..';
