sending and reading data on the same page

[peuge]

I have made a simple table in PHP and I want to send the entered data to the same page. Once this is done I want to read it from the same page. Is this possible or do I have to send it to another page?

 

echo "<table>";

echo "<form method=post action=What do I put here]>";

echo "<input type=text name=num id=num>";

echo "<input type=submit name=submit value=submit>";

echo "</form>";

echo "</table>";

[trq]

<?php

if (isset($_POST['submit'])) {
  echo $_POST['num'];
} else {
  echo "<table>";
  echo "<form method=post action=''>";
  echo "<input type=text name=num id=num>";
  echo "<input type=submit name=submit value=submit>";
  echo "</form>";
  echo "</table>";

}

You could also do:

action='{$_SERVER['REQUEST_URI']}'

But either works fine.
