寻找有关如何创建简单文本编辑器的教程？ [关闭]

I'm looking for a tutorial(s) on how to create a simple text editor. I'm using PHP, MySQL and Jquery on my site?

why not just use http://ckeditor.com or any of the many other existing editors. Reinventing the wheel is dumb

a simple text editor

<?
if ($_POST) {
  file_put_contents("file.txt",$_POST['text']);
  header ("Location: ".$_SERVER['PHP_SELF']);
  exit;
}
$text = htmlspecialchars(file_get_contents("file.txt"));
?>
<form method="POST">
<textarea name="text"><?=$text?></textarea>
<input type="submit">
</form>

I wouldn't call it tutorial, but I think Mozilla's Midasdemo is a good entry.
