unset array

[Nico]

Hi all,

I've created the following code:

<?php

session_start() ;
?>
<FORM METHOD="POST" ACTION="prova.p hp">
Add <b>Combinatio n</b><br><br>
Element 1: <INPUT NAME="el1add" TYPE="TEXT">
<BR>
Element 2: <INPUT NAME="el2add" TYPE="TEXT">
<br>
<INPUT TYPE="SUBMIT" VALUE"Submit">
</FORM>
<br>
<FORM METHOD="POST" ACTION="prova.p hp">

Del <b>Combinatio n</b><br><br>
Element 1: <INPUT NAME="el1del" TYPE="TEXT">
<BR>
Element 2: <INPUT NAME="el2del" TYPE="TEXT">
<br>
<INPUT TYPE="SUBMIT" VALUE"Submit">
</FORM>
<br><br>
Combination<br> <br>
<?php
$_SESSION["combinatio ns"][] =
($_REQUEST["el1add"].$_REQUEST["el2add"]);
unset($_SESSION["combinatio ns"][$_REQUEST["$el1del"]]);
unset($_SESSION["combinatio ns"][$_REQUEST["$el2del"]]);
print_r($_SESSI ON["combinatio ns"]);
?>

I'd like to create an array combinations which includes all the
combinations that I insert through the first form (add combinations).

ref:
$_SESSION["combinatio ns"][] = ($_REQUEST["el1add"].$_REQUEST["el2add"]);

This works fine and is OK.
Then, I'd like to delete from the array combinations all the
combinations that I insert through the second form (del combinations).

ref:
unset($_SESSION["combinatio ns"][$_REQUEST["$el1del"]]);
unset($_SESSION["combinatio ns"][$_REQUEST["$el2del"]]);

This second part doesn't work.
In particular, I want to delete all the elements of the array
$_SESSION["combinatio ns"] that include $_REQUEST["$el1del"] or
$_REQUEST["$el2del"] as text (not as key). I've some problem in doing it.
Can you help me please?
Many thanks.

Cheers,
Nico

Some extra $-signs in there.
