#24 - fail to check line in boundaries

[hitapia]

#24 - I have a problem, when I use function 'getBody()'

The boundaries array should have no space, but it's not.

if (is_array($boundaries)) {
    if (in_array(substr($line, 2), $boundaries)) {  // found the delimiter
        break;
    }
}

When checking line in boundaries array, It's fail always in my case.

Please review my pull request.

p.s. It's my first time to pull request in GitHub and my eng. is not good. :)
Thanks.
