CKeditor is an open source HTML text editor. For adding CKeditor we need to create a <textarea> element in our web page and call CKeditor script.
We are going to create 3 files ie, ckeditor.html, upload.js, upload.php and an image folder to upload image.
1) ckeditor.html: HTML with a textarea element.
2) upload.js: Script to display CKeditor and Upload tab in image properties.
3) upload.php: Code for uploading images in image folder.
