PHP how to specify "back one directory level" in an url

Question

I have moved all of my files from being in the root (no folders, not very organised) so that they now reside within the following directory structure in my root folder:

css
images
js
scripts
index.html

... and this is fine. However, I have two or three php scripts which upload files (images) into the images folder above. This worked fine until I moved all of my files around and now I have been experimenting with things like "../" etc in order to link from the scripts directory, back one level, and then into the images directory.

Any help appreciated guys....

Solution 1

Using what you stated above will work, so if you're in css and want to go to images (as an example) you would do the following:

require_once('../images/yourimg.png');

Solution 2

The require_once is simular to the require() statement but it checks wheter the file has been included already, and if it did, then it won't be included again.

Now for your question, if you have something like:

yoursiteurl/scripts/myscript.php

And you want that script to write a file to

yoursiteurl/images/sampleimage.jpg

Then you should reference the image destination to something like this:

copy('source/file/location/sampleimage.jpg', '../images/sampleimage.jpg')
