Requesting Info...Help!

[melvnatic]

How do you ask a visitor something and store his/her reply to a variable? And also, is it possible to delete a session variable when the visitor closes the browser or exits the page? Thank you!

actually, i meant form fields...how do you create a box where, when the user presses submit, it saves the info to a variable?

Generally, the page has to be reloaded in order to take input from a field and put it into a variable:
[code]<?php
if(isset($_POST['name'])) {
    $name = $_POST['name'];
    echo "Your name is $name!";
}
?>
<form name="name" action="" method="post">
    <input type="text" name="name"/>
    <input type="submit" name="submit" value="GO!"/>
</form>[/code]
With regards to session variables, I think they are destroyed when the browser is closed, although you could clear the session data with something like $_SESSION = array();
