What is Select2 and how is it used in PHP for database search functionality?

Select2 is a jQuery-based replacement for select boxes. It provides a user-friendly interface for selecting options from a dropdown list with features such as searching, tagging, infinite scrolling, and remote data loading. In PHP, Select2 can be used to enhance the search functionality of a database by allowing users to easily search and select options from a large dataset.
