Editing and Reading an External Document

How do you edit and read an external document?

[CoolJRT2009]

Hi.
I am making a website that needs to edit and read an external document.
How could I do this? I have searched through Google [google.com.au] and couldn't find anything. Except other forums.
If I have 2 text boxes, for example:
Title: <input name="Title"><br>
Content: <input name="Content"><br>
<input type="button" value="Save">

I need the button Save to edit the document.
And then on another page:
<input type="button" value="Refresh Information" onclick="?"><br>
Title: <input name="Title"><br>
Content: <input name="Content"><br>
<input type="button" value="Save" onclick="?">
Here, I need the Save button to save it and the Refresh Information to read it.

Thanks.
From Hayden.

You are going to need some server-side scripting for this one. Read up on one (eg PHP [php.net]) and see where you get.

You have 2 main avenues (that i know of) with php, using a MySQL database or using XML. Both ways can be found on php.net as linked to by eelixduppy.
