Retrieving array element from $_SESSION[] or $_POST[]

[redlamb]

Is there a way to get access to an array element using the $POST or $SESSION variable? I have a form that is populating an array on submission, but i can't figure out how to get just a particular element from an array.

I tried:
$element = $_POST["array[1]"]

but that didnt work. Is there a way to do this or do i have to first assign $_POST["array"] to a variable and then access it that way?

Next question, is it ok to have arrays stores within a session variable? I wasnt too sure on this one and I havent been able to find any info about it on the net.

Thanks in advance.

You talking about this...?

$element = $_POST[$array[1]];

No, that isnt exactly what I am trying to do. Let me try and explain it a little better. In the html form, I have:

<input type=text name=company[0]><br>
<input type=text name=company[1]><br>
<input type=text name=company[2]><br>

When the form is submitted, I only need to get the values of company[1] and company[2] if company[0] is a specific value. So, I was wondering how I check that value using the $_POST variable. I know that I could check it doing:

$a = $_POST["company"];
if ( $a == 'something' )
...

but i was wondering if there is a way to do it without the step of assigning the array to a variable first such as:

if ( $_POST["company[0]"] == 'something' )
....

But that doesnt work. Hope that makes better sense. Thanks in advance.
