Which way of writing do you like more?

gistfile1.php

// first way
// standard 
$example->foo(2, 2)->andReturn(4)
    ->foo(4, 4)->andReturn(8)
    ->foo(8, 8)->andReturn(16);

// second way
// Same functionality as well indented and the first line is as readable as the following lines.
$example
    ->foo(2, 2)->andReturn(4)
    ->foo(4, 4)->andReturn(8)
    ->foo(8, 8)->andReturn(16);
