i got php codes here for book.php$,$ DatabaseConnection.php$,$ Functions.php and they are working correctly with main.php code below.

i am trying to built a library management system that will addBook, displayBooks and searchBook

The escatic of the web application should be moden, therefore add colur to it

book.php

title $=$ $title;

$this$->$author $=$ $author;

$this$->$isbn $=$ $isbn;

$this$->$genre $=$ $genre;

$\}$

$//$ Getter methods for book properties

public function getTitle$()$

$\{$

return $this$->$title;

$\}$

public function getAuthor$()$

$\{$

return $this$->$author;

$\}$

public function getISBN$()$

$\{$

return $this$->$isbn;

$\}$

public function getGenre$()$

$\{$

return $this$->$genre;

$\}$

$//$ Method to display book information
