Thanx a lot for your help.I tried some other examples in a book named Mastering PHP that i'd like to discuss with you.
They are as follows:

<html>
    <head><title></title></head>

<body>
    <form action="you_are_adv.php" method ="GET">
        Please fill in the following fields:</br>

        <?php
            $favourite_lang="PHP";

        ?>
        <b>First Name:</b>
        <input type="text" name="first" value="<?php print($first); ?>" size="15"><br/>

        <b>Last Name:</b>
        <input type="text" name="last" value="<?php print($last); ?>" size="15"><br/>

        <b>Favourite Programming Language:</b>
        <input type="text" name="favourite_lang" value="<?php print($favourite_lang); ?>" size="15"></br>

        <input type="submit" value="Go!" size="15">

    </form>
</body>
</html>

<html>
    <head><title></title></head>
    <body>
        Hello<b><?php print($first . " " . $last);?></b>

        I am glad to know your favourite programming language
        is<?php print($favourite_lang); ?>

        <?php
        $query_string="";
        $query_string .= "?first" .urlencode($first);
        $query_string .= "&last=" .urlencode($last);
        $query_string .= "&favourite_lang=" .urlencode($favourite_lang);
        ?>
        <br/><br/>
        <a href="who_are_you_adv.php<?php print($query_string) ?>">
        Back to who are you advanced
        </a>
    </body>
</html>
The output was something like this after entering text and clicking the submit(GO) button:
(Hello I am glad to know your favourite programming language is

Back to who are you advanced)
And in the adress bar of the you_are_adv.php page i see the following:
(http://127.0.0.1/you_are_adv.php?fir...urite_lang=PHP)

Now what is really going on?
What is the importance of urlencode???
Waiting for your reply...

Well, urlencode (http://uk2.php.net/manual/en/function.urlencode.php) will replace any prohibited characters in a querystring, like a space, with their escaped equivalents (so, that a querystring of '?first=William&last=Arbuthnal Higgin' becomes '?first=William&last=Arbuthnal%20Higgins'). You must retrieve the values you sent from the submission form by assigning them to local variables (via $first=$_GET['first'], and so on). Since the browser would have urlencoded the values sent from the form, anyway, you will have to make a call to urldecode (http://uk2.php.net/manual/en/function.urldecode.php), to cater for the 'William Arbuthal Higgins'es of this world, as in:
$last = urldecode($_GET['last'];

HTH
