For a few reasons i started an online php file editor.
Does line numbers.
Will edit files with textarea tags.
Line Numbers are links back to the top for convenience to save
Search, and find and replace.
Noticed a few differences between using IE and Mozilla.
You will have to try it with your browser.
No java or client side scripting, php server side. but it seems they display a little different.
For a few reasons, Does not do directory traversing. (jusk copy the page and change the Dir)
not designed for multi users. one login name and password. (You can copy the page and make different loggins *also see above*)
