CKEditor is a WYSIWYG HTML editor.
It makes HTML textarea lot more user-friendly by providing various features like – adding images, writing HTML code, formatting text, etc.
This can also be added to HTML containers.
It does not depend on other libraries like – jQuery and can be used in 3 different modes – Article Editor, Document Editor, and Inline Editor.
Different options are available to customize the editor.
In this tutorial, I am adding Article and Inline mode CKEditor on the same page and save it to MySQL database on submit with PHP.
