Installation

Usage

Creating a New EPub Book

To create a new EPub book, you need to instantiate the EPubBook class and provide the book's title:

use tregor\epub\EPubBook;

$book = new EPubBook('My First Book');

Parsing an Existing EPub Book

You can also parse an existing EPub book and retrieve its information. To do this, use the open method:

$book = EPubBook::open('existing_book.epub');

Setting Book Metadata

You can set the author and language of the book using the setAuthor and setLanguage methods:

$book->setAuthor('John Doe');
$book->setLanguage('en');

Adding Chapters

You can add chapters to the book using the addChapter method. Each chapter requires a title, content, and order:

$book->addChapter('Chapter 1', 'This is the first chapter.', 1);
$book->addChapter('Chapter 2', 'This is the second chapter.', 2);

Rearranging Chapters

You can add a new chapter after an existing chapter by specifying the order of the existing chapter, the title and content of the new chapter, and the new order:

$book->addChapterAfter(1, 'Chapter 2', 'This is the new Chapter 2.', 2);

Removing Chapters

To remove a chapter from the book, specify its order:

$book->removeChapter(2);

Updating Chapters

You can update the content of a chapter by specifying its order and providing the new content:

$book->setChapterContent(1, 'This is the updated content of Chapter 1.');

Exporting the EPub Book

Once you have added all the chapters, you can export the EPub book to a file using the export method:

$book->export('my_first_book.epub');

Here are the available methods provided by the EPubBook class:

• __construct($title): Creates a new EPubBook object with the specified title.
