How does this print “hello world”?

Question

I discovered this oddity:

for (long l = 4946144450195624l; l > 0; l >>= 5)
    System.out.print((char) (((l & 31 | 64) % 95) + 32));

Answer 1

I found the code slightly easier to understand when translated into PHP, as follows:

 0; $bignum >>= 5){
    $result = (( $bignum & 31 | 64) % 95) + 32;
    echo chr($result);
}
