PHP form

My HTML form submits the data to a php form. I was wondering if I could "save" the data in the php form so whoever opens it can see the data. Atm, if I open "action.php" from a different computer I see "hi you are 0 years old"

Here's the code

Code:

<html>

<head> </head>

<title> Form </title>

<body>

<form action="action.php" method="post">
<p> your name: <input type="text" name="name" /> </p>
<p> your age: <input type="text" name="age" /> </p>
<p> <input type="submit" /> </p>
</form>
</body>
</html>

Code:

hi <?php echo htmlspecialchars($_POST['name']); ?>
you are <?php echo (int)$_POST['age']; ?> years old

The $_POST data is specific to the connection, so if I enter some data it will be POST'ed to the web server on my connection. If you then connect to the web server you establish a separate connection and if you send some data then it will be POST'ed along your connection.

So the $_POST data is specific to the connection, if you want everyone to be able to see a history of what has been sent (much like this forum) then you need to get PHP to save the data in some permanent format, such as a file, or a database.

Is it easier to use Perl's CGI.pm instead of PHP then? AFAIK, CGI.pm can do this thing without having to save the data to a backend database.

Which is easier?
It depends upon which you know, both will need to store the data somewhere, it could just be a file but it needs to store it somewhere because that is how HTTP works, it is a connection based protocol. It's relatively easy in PHP.
