unset() works for any variable - also for the superglobals like $_POST.
Try this:

--------------------[cut here]-------------------- 
<xmp>
<?php
print_r($_POST);
echo 'F1 = ', $_POST['f1'], "\nF2 = ", $_POST['f2'], "\n";
unset($_POST['f2']);
print_r($_POST);
?>
</xmp>
<form method="POST">
<input type="text" name="f1" value="<?php echo $_POST['f1'];?>">
<br>
<input type="text" name="f2" value="<?php echo $_POST['f2'];?>">
<br>
<input type="submit">
</form>
--------------------[/cut here]-------------------- 

What error do you get? Make sure you're using the correct case - PHP is
case sensitive in variable names and associative index keys...
