如何在mysql表列中检索数据？

In Mysql Table, I've a table name: mental_illness that there's two enum row inside as :

N and P

It means Negative and Positive

and here's my PHP code to retrieve data from that table:

  if ($history->getMentalIllness())
  {
    echo HTML::section(3, _("Mental Illness : "));
    echo HTML::para(nl2br($history->getMentalIllness()));
  }

Here's my question:

How to use if else in that above PHP code like this:

If Mental Illness is P, then show Positive text and If Mental Illness is N then show Negative text

Because this code just show P and N instead of Negative and Positive text.

Thank you

Just do:

if ($history->getMentalIllness())
{
  echo HTML::section(3, _("Mental Illness : "));
  if($history->getMentalIllness() == 'P'){
    $mental_illness = "Positive";
  }else{
    $mental_illness = "Negative";
  }
  echo HTML::para(nl2br($mental_illness));
}

One more thing... Why would you need nl2br in this case... There are no newlines in these two strings...
