PHP - HOW TO View Info About the Current Directory/Folders/Files via PHP Code

Home Short:

Trying to get information about the current directly you are in via PHP can be a bit confusing with all the various PHP functions related to listing information about the current directory.

For the code examples below, we will pretend we are running the php from a url on our website https://www.vb6code.com/phpcode/examples/code-php-current-directory-file-functions.php

Get the full server filepath to the current page calling the script:
- getcwd() OR dirname(__FILE__).
  - returns, ie, /elmo/walweb04/walweb04ac/d793/moo.isspybubbleascamcom/vb6code.com/phpcode/examples/. Note that the last listed item listed to the right is the current folder.
Get the current folder only:
- basename(dirname(__FILE__)) OR basename(__DIR__).
  - Returns, ie, examples.
To get all the folders leading to the current page:
- dirname($_SERVER[PHP_SELF]).
  - Returns, ie, /phpcode/examples.
To get the protocol for the actual url for the current page protocol example, http:// or https://:
- $protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://".
  - The variable $protocol now contains either http:// or https://.
To get the host of part of the actual url for the current page:
- $_SERVER['HTTP_HOST'].
  - Returns, ie, vb6code.com.
To get the rest of the url to the current page which would include any folders/sub folders and the current file also referred to as the path of the url:
- $_SERVER['REQUEST_URI'].
  - Returns, ie, /phpcode/examples/code-php-current-directory-file-functions.php.
To get the full url to the current page, you connect or concate the above three examples:
- $protocol . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'].
  - Returns, ie, https://www.vb6code.com/phpcode/examples/code-php-current-directory-file-functions.php.

You can test these file/folder functions on your web server by copying and pasting the code below into a text file and saving as .php.

<?php
echo "<input type=\"text\" style=\"text-align:right;width:250px;\" value=\"getcwd() = \">" . " " . getcwd() . "<br>";
echo "<input type=\"text\" style=\"text-align:right;width:250px;\" value=\"dirname(__FILE__) = \">" . " " .  dirname(__FILE__) . "<br>";
echo "<input type=\"text\" style=\"text-align:right;width:250px;\" value=\"basename(dirname(__FILE__)) = \">" . " " . basename(dirname(__FILE__)) . "<br>";
echo "<input type=\"text\" style=\"text-align:right;width:250px;\" value=\"basename(__DIR__) = \">" . " " .  basename(__DIR__) . "<br>";
echo "<input type=\"text\" style=\"text-align:right;width:250px;\" value=\"dirname($_SERVER[PHP_SELF]) = \">" . " " . dirname($_SERVER[PHP_SELF]) . "<br>";
$protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
echo "<input type=\"text\" style=\"text-align:right;width:250px;\" value=\"$protocol = \">" . " " . $protocol . "<br>";
echo "<input type=\"text\" style=\"text-align:right;width:250px;\" value=\"$_SERVER['HTTP_HOST'] = \">" . " " . $_SERVER['HTTP_HOST'] . "<br>";
echo "<input type=\"text\" style=\"text-align:right;width:250px;\" value=\"$_SERVER['REQUEST_URI'] = \">" . " " . $_SERVER['REQUEST_URI'] . "<br>"; 
?>

If you have a url and you want to parse the url into its different parts you can use the PHP parse_url function.

We will use the example url https://www.vb6code.com/phpcode/examples/code-php-current-directory-file-functions.php?r=affiliate

First you call the parse_url function, passing the url you want to parse.

To get all the scheme of the parsed url:
- $arrparts['scheme'].
  - Returns, ie, https://.
To get all the host of the parsed url:
- $arrparts['host'].
  - Returns, ie, vb6code.com.
To get all the path of the parsed url:
- $arrparts['path'].
  - Returns, ie, /phpcode/examples/code-php-current-directory-file-functions.php.
To get all the query string of the parsed url:
- $arrparts['query'].
  - Returns, ie, r=affiliate.
