Learning AJAX

[blueparukia]

OK, so I have a few Ajax questions that Zinga will know

1. Can you execute specific PHP functions?
Say all my PHP file contains is

PHP Code:

<? function name(){echo "something";} ?>

---

Is it possible to specify (in the JS) to execute only that function?

2. Retrieving a value from an input

How do I do this in the PHP. Say I have

HTML Code

<input name="input" type="text">

---

  

How do I transfer that to the PHP form without submitting it? Via $_GET?.

That is all my incredibly inportant questions,
