This sample shows how to replace a selected <textarea> element
with a CKEditor instance by using PHP code.
To replace a <textarea> element, place the following call at any point
after the <textarea> element:
<?php
// Include the CKEditor class.
include_once "ckeditor/ckeditor.php";
// Create a class instance.
$CKEditor = new CKEditor();
// Path to the CKEditor directory.
$CKEditor->basePath = '/ckeditor/';
// Replace a textarea element with an id (or name) of "textarea_id".
$CKEditor->replace("textarea_id");
?>
Note that textarea_id in the code above is the id attribute of
the <textarea> element to be replaced.
