Directory Listing/Relative URL

[KooLTaB101]

Hi,

I am trying to create a line item at the top of my page that is dynamic in that it tells users where they are in relation to the home page. For example, if they are at the homepage, the line would say "Home/" and if they were in a folder "Directory 2", it would say "Home/ Directory 2/." Also, they should be hyperlinks so they can get to "Home" rather quickly by simply clicking on it. I have each of my pages call a specific page using the require call tag. The line item would be in that one specific page...but if need be, I could probably make due of the line item could be on each specific page. Let me try to give some examples:

Home
index.php
page1.php
/Directory 2
page2.php

So that if Home/Directory 2/page2.php was called, it would export that in the line item.

Also, the require tag calls index1.php in the following way: <? require 'index1.php'; ?>

I hope all this makes sense as in what I am trying to do. If need be, I can give more examples to clear it up.

Thanks,
Matt

It's not too hard.

$_SERVER['PHP_SELF'] contains the path, relative to the web site's document root, of the script invoked by the web server.

All you have to do is split that value at whatever is the correct file/directory separator for your operating system, then wrap the pieces in <a>...</a> tags. Want the best answers? Ask the best questions:

I am still a little rusty at php. Could you give me a complete code?

Thanks for the help,
Matt

No. By policy, I only post code when my answer would be less clear without it. Depending on your typographical style of editing source code, this will only be a 3 to 5 line script.

$_SERVER is documented here:

http://www.php.net/manual/en/reserved.variables.php

split() is documented here:

http://www.php.net/manual/en/function.split.php

since split() returns an array, you might be interested in foreach():
