unusual ternary operation

Question

I was asked to perform this operation of ternary operator use:

$test=\'one\';

echo $test == \'one\' ? \'one\' :  $test == \'two\' ? \'two\' : \'three\';


        

Answer 1

Nested ternary operations are gross! The above explanation shows why.

Basically this is the logic:

is $test == 'one'

  if TRUE then echo 'one'

  else is $test == 'two'

      if TRUE then echo 'two'

      else echo three
