This PHP script is a simple HTTP status code handler, designed to provide informative and human-readable error messages for a wide range of HTTP status codes. From informational and success codes to client errors and server errors, it aims to provide useful feedback based on the status code it receives.

The script starts by getting the REDIRECT_STATUS value from the $_SERVER superglobal. If the status code is present in the predefined list of codes, it fetches the corresponding title and message. If the status code is not in the list but is a valid 3-digit code, a generic message is displayed. If the received status is not a valid 3-digit code, an error is thrown with information about the server and environment variables.

In case of an unexpected error, the script catches the exception, displays the exception message, and prints the exception trace.

To use this custom error handling script effectively, you need to setup your .htaccess file to redirect error requests to it. Here's a basic example of how you can do this:

ErrorDocument 400 /error-handler.php
ErrorDocument 401 /error-handler.php
ErrorDocument 403 /error-handler.php
ErrorDocument 404 /error-handler.php
ErrorDocument 500 /error-handler.php
# ... and so on for each error code you want to handle

In this example, /error-handler.php should be the path to the error handling script relative to the web root.

If your script is not at the root directory, adjust the path accordingly. For example, if your script is inside an includes directory, you would use:

ErrorDocument 400 /includes/error-handler.php
# ...

Remember that the .htaccess file should be in the root directory of your website. If it's not already there, you'll need to create it.

Please note that usage of .htaccess files requires the server to be running Apache and have the AllowOverride directive enabled. If you're using a different server such as Nginx or if AllowOverride is disabled, you would need to use a different method to redirect error requests to the script.

To use this script, simply include it at the beginning of your PHP file:

<?php
require 'http_status_handler.php';

Make sure to replace 'http_status_handler.php' with the actual path to this script.

Once included, the script will automatically handle any HTTP status code it encounters.
