libmongoc uses case-insensitive parsing for options in the URI string, as does php_phongo_make_uri() for options in Manager's second array argument; however, phongo_stream_initiator() was using case-sensitive bson_iter_init_find() to retrieve the "connectTimeoutMS" option to apply to the PHP stream. We should either use bson_iter_init_find_case() or mongoc_uri_get_option_as_int32() instead.
