Create an application with file upload functionality.

Project Specifications:

1. Convert the form with the following input fields into valid HTML:

   • File input (image/*) (file selection)
   • Text input (alternate text)

2. Establish a database with a table to store images, having the following columns:

   • ID
   • Path (file path)
   • Alt (alternate text)

3. Develop a class for file uploads, which includes the following tasks:

   • Alternative text validation
   • File type validation
   • File size validation
   • Generate a date-coded path (e.g., 31/12/2022)
   • Rename files to avoid duplicates (overwriting)
   • Upload files to the date-coded path

4. Build a database connection using PDO.

5. Store relative file paths and alternate text as new entries in the database table.

6. If the upload is successful, output a JSON string containing all information about the new database entry:

   • Include the content type as Application/JSON in the response header.
   • Return HTTP status code 201.

7. If the upload fails, output a JSON string with error messages related to the file upload:

   • Include the content type as Application/JSON in the response header.
   • Return HTTP status code 422.
