What is wrong with my array syntax?

Question

So I'm having a problem with arrays:

print_r($_POST['bank']);

produces the following output:

Array ( ['deposit'] => 30 ) 

However,

assert($_POST['bank']['deposit']==30);

which immediately follows print_r, fails. I feel like an idiot, but could someone help me out? Since nothing is changing the value of $_POST, I suppose my syntax is wrong, but I can't see it for the life of me.

Answer 1

Try doing

assert(intval($_POST['bank']['deposit']) == 30);

Answer 2

Ugh, I just realized it.

assert($_POST['bank']['\'deposit\'']==30);

works fine, because "deposit" had had extra single quotes around it.
