There is another way to do it.
Let's say you have a form
$form="
<form method=post action=$PHP_SELF>
<input type=text name=text1 (this is where the trickcomes) <b>value=$text1</b>
<input type=text name=text2 value=$text2>
etc...
<input type=submit>";
echo "$form";
When user goes back all the values will stay in the form.
