FCPATH in CodeIgniter

### 📌 What is `FCPATH`?
`FCPATH` is a predefined constant in CodeIgniter that gives the **full server path to the `index.php`** file (the front controller of the application).

### ✅ Example:
If your project is located at:

/var/www/html/myapp/

and the `index.php` file is here:

/var/www/html/myapp/index.php

Then:

echo FCPATH;
// Output: /var/www/html/myapp/

—

### 🛠️ Common Use Cases:
1. **When including/creating files in the root**:

require_once FCPATH . 'vendor/autoload.php';

2. **When saving uploaded files**:

$target_path = FCPATH . 'uploads/' . $filename;

—

### 🧠 Where is `FCPATH` defined?
It is defined in `index.php`:

define('FCPATH', __DIR__ . DIRECTORY_SEPARATOR);

—

Let me know if you're using CodeIgniter 4 — the concept is similar, but CI4 uses a different structure (like `ROOTPATH`, `APPPATH`, etc.).

—

### ✅ Option 1: Manually redefine `FCPATH` at the top of `index.php`

In `fossetts_admin/index.php`, locate this line:

define('FCPATH', __DIR__ . DIRECTORY_SEPARATOR);

Replace it with:

define('FCPATH', realpath(__DIR__ . '/../') . DIRECTORY_SEPARATOR);

This will set `FCPATH` to:

/home/fossetts/public_html/boxoffice/

💡 `__DIR__ . '/../'` moves one level up from the `fossetts_admin` directory.

—

### 🧪 To test:

echo FCPATH;
// Output: /home/fossetts/public_html/boxoffice/

—

### ✅ Option 2: Define your own constant (if you still want to use default FCPATH)

If you need both:
– The default `FCPATH` (for public file access),
– And another constant pointing to the parent directory,

You can do:

define('BOXOFFICE_PATH', realpath(__DIR__ . '/../') . DIRECTORY_SEPARATOR);

Then use `BOXOFFICE_PATH` wherever needed.

Let me know if your `index.php` is in a different location or if you're routing URLs differently via `.htaccess`.
