How to use multiple ternary conditions on the same line?

Example: 

echo ($estado == 'SP' ? 'São Paulo' : ($estado == 'RJ' ? 'Rio de Janeiro') : ($estado == 'PR' ? 'Paraná') : 'teste');

This is giving you an error!

You can even use this but, as you can see, the readability of the code looks awful. 

echo
($estado == 'SP' ? 
   'São Paulo' : 
   ($estado == 'RJ' ? 
      'Rio de Janeiro') : 
      ($estado == 'PR' ? 'Paraná') : 
          'teste');

The correct assembly would look like this: 

echo
($estado == 'SP' ? 
   'São Paulo' : 
   ($estado == 'RJ' ? 
      'Rio de Janeiro' : 
      ($estado == 'PR' ?
          'Paraná' : 
          'teste')
    )
 );

//em uma linha só:
echo ($estado == 'SP' ? 'São Paulo' : ($estado == 'RJ' ? 'Rio de Janeiro' : ($estado == 'PR' ? 'Paraná' : 'teste')));

remembering : In cases with more than one validation, it is more interesting to use if or switch .
