Trying to get a full URL without filename in PHP

Question

I thought this would be simple but I can't seem to find a variable of $_SERVER array that has what I'm looking for.

Let's say my url is http://example.com/subdirectory/index.php I want to get all but the filename - http://example.com/subdirectory/.

I know I could quite easily do this with some string manipulation, but I want to know if there's a var of the _server array that I'm just missing. I've tried all of them to see what they give and I can get anything BUT what I'm looking for.

Answer 1

There won't be one because it's not a useful attribute to track. If the current script is something other than index.* then it will not return the correct URL for the current script.

However, this might get you what you want:

echo '//'.$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']); 

Edit:
Also, aside from installing the php.net online manual search tool for Firefox and setting it up with a search keyword (which will let you pull up the documentation on the $_SERVER global by typing something like "php $_server" into your URL bar), you should also know that var_dump() and print_r() lets you output the full contents of any variable, including arrays and objects. This is very useful for debugging.

Answer 2

In your case, string manipulation is the best solution.

For Example:

substr($_SERVER['REQUEST_URI'], 0, strrpos($_SERVER['REQUEST_URI'], '/') + 1);
