Relative URL's/paths in php

Question

Hi this is the first time I am asking a question here.

I have a image src as

src="images//images/pixel.gif" 

But I dont understand this double forward slashes (//) in the src.

Also what is the meaning of "./" and "../" in a relative file path like in below src:

src="./images/pixel.gif" 
src="../images/pixel.gif" 

Answer 1

An initial / means the root of the web page.

A directory entry with name . means the same directory. If it's at the beginning, it normally means something like "here" and mostly used to clarify that the path is relative to the present location.

A directory entry with name .. means the parent directory. So, this means going up the directory tree.

If two or more / are consecutive, this cancels all previous path and replaces with the root of the web page.

That said,

src="images//images/pixel.gif" means /images/pixel.gif (directly at the root directory, a folder with name images, and then the file.

src="./images/pixel.gif" means a directory images inside the same directory where the loaded page resides (the one containing the reference to the image). Remember the here concept. You could also write directly src="images/pixel.gif".

src="../images/pixel.gif" means going up to the parent directory in which resides the loaded page and then go down to a directory named images. Remember the parent concept.

Hope helped!
