What does this simple command means in PHP?

I have found this command written in PHP, but I cannot understand what it does... I have seen an introduction to arrays for PHP, but still, I can't figure this out.

$from=1;
$A['from'] = $A[$from];

What is the programmer here doing? I mean, how he can assign $A[$from] somewhere, since $A[$from] has not get any values (array A is not used before). And what this command does?
