$a is an associative map with some things in it: array ( 'foo' => 'bar', 'baz' => 'quux', 100 => 'zimbabwe', ) It has these keys: array ( 0 => 'foo', 1 => 'baz', 2 => 100, ) But there was a silent string-int coercion when we added an object to the container using a string key that looked like an int bool(false)
