I've was working on some old parts of a website and found myself in a situation where I have to run the following code 

<?=($stone->2_way)? 'checked' : ''?>

Attempting to do this causes the page to crash while this 

<?=($stone->rectangular)? 'checked' : ''?>

doesn't. I'm wondering if it is because the variable starts with a number? I can var_dump the stone object and get 

object(Cut_Stone)#54 (6) {
  ["errors"]=>
  NULL
  ["attributes":"ActiveRecord\Model":private]=>
  array(13) {
    ["stone_id"]=>
    int(24)
    ["stone_name"]=>
    string(11) "Test Stone "
    ["active"]=>
    int(1)
    ["rectangular"]=>
    int(1)
    ["2_way"]=>
    int(1)
    ["3_piece_radius"]=>
    int(1)
    ["3_piece_straight"]=>
    int(1)
    ["wedge"]=>
    int(1)
    ["partial_wash"]=>
    int(1)
    ["pier_cap"]=>
    int(1)
    ["pier_cap_w_flat"]=>
    int(1)
    ["radiused_hearth"]=>
    int(1)
    ["total_washed"]=>
    int(1)
  }
  ["__dirty":"ActiveRecord\Model":private]=>
  array(0) {
  }
  ["__readonly":"ActiveRecord\Model":private]=>
  bool(false)
  ["__relationships":"ActiveRecord\Model":private]=>
  array(0) {
  }
  ["__new_record":"ActiveRecord\Model":private]=>
  bool(false)
}

Also it is important to note that this object has been used in other places without fail, so I don't really get what is going on here.

Try using brackets and quotes around the property name: 

<?=($stone->{'2_way'})? 'checked' : ''?>
