A question about count in Php

Question

I have noticed in the challenge that:
echo count(array(true=>1,false=>2,0=>3,1=>4));
gives 2. I think count does counts the keys, because true is 1 and false is 0, it gives 0. Am I right, inshaALLAH?

Answer 1

Yusuf , it's because old values for the same keys are replaced with the new ones (as you mentioned there are duplicate keys (0 and false and 1 and true). Finally associative array is (1=>4, 0=>3).
