Setting multidemensional POST array with variable

Question

I understand how to set POST variables ($_POST['u'] = 10), and I understand how to call a multi-demensional post value ($_POST['u']['number2']), so to set a simple multi-demensional POST, it'd be simple ($_POST['u']['number2'] = 10).

The problem comes when I need to set a POST variable by use of a variable, i.e., $_POST['u']['$number'] = $number2, where $number is a string from a loop.

What's going on is the loop takes data from the POST[u][$number], manipulates it, spits out $number2, and I'm wanting to update the POST[u][$number] with $number2, if that makes any sense.

So, basically, is there anyway for me to do $_POST['u']['$number'] = $number2?

I tried using eval but that didn't work...

Single quotes parse literal strings!

Maybe you mean:

$_POST['u'][$number] = $number2;

Without single quote. Or even:

$_POST['u']["{$number}"] = $number2; //> Discouraged
