Error Handling

Demonstrates the FileException scenarios thrown by the library.

What It Covers

Six error conditions, each caught with try/catch:

1. File not found — read() on a path that doesn't exist
2. Empty file name — read() with no name set
3. Empty path — read() with a name but no directory (and file not in calling script's directory)
4. No data to write — write() without calling setRawData() first
5. Read past end of file — read($from, $to) where $to exceeds the file size
6. Invalid Base64 — setRawData($data, true, true) with strict mode on invalid input

Key Class

• WebFiori\File\Exceptions\FileException — Extends PHP's Exception. Thrown by File and FileUploader methods on error.
