When you make form in (X)HTML like this :

[code]
<form metod="post" action="page.php">
<input name="b" type="text" />
</form>
[/code]

note the method in form tag :) it's post , so any "input" in this form will save in $_POST array .

try :
[code]print_r($_POST);[/code]

in page.php :)

POST is a method of passing data between scripts. Here's an example:
[code]<form name="test" action="next.php" method="POST">
<input type="name" name="name"/>
<input type="submit" name="submit" value="GO!"/>
</form>

//PHP page "next.php"
<?php
echo "Hello $_POST[name]";
?>[/code]
