How to write a PHP ternary operator

Question

How do I write a PHP ternary operator with the elseif portion   I see basic examples with the if and else portions of the PHP ternary operator like this   echo  true      yes     no        prints yes echo  false     yes     no        prints no   How do I get the  elseif  portion like this into the ternary operator    lt  php    if  result- gt vocation    1       echo  Sorcerer       else if  result- gt vocation    2       echo  Druid      else if  result- gt vocation    3       echo  Paladin      else if  result- gt vocation    4       echo  Knight      else if  result- gt vocation    5       echo  Master Sorcerer      else if  result- gt vocation    6       echo  Elder Druid      else if  result- gt vocation    7       echo  Royal Paladin      else      echo  Elite Knight         gt

You wouldn   t  it   s messy and hard to read    You   re looking for the switch statement in the first case  The second is fine as it is but still could be converted for consistency   Ternary statements are much more suited to boolean values and alternating logic

echo   result - gt vocation    1     Sorcerer              result- gt vocation    2     Druid                  result- gt vocation    3     Paladin                                It   s kind of ugly  You should stick with normal if statements

In addition to all the other answers  you could use switch  But it does seem a bit long   switch   result- gt vocation    case 1      echo  Sorcerer       break   case 2      echo  Druid       break   case 3      echo  Paladin       break   case 4      echo  Knight       break   case 5      echo  Master Sorcerer       break   case 6      echo  Elder Druid       break   case 7      echo  Royal Paladin       break   default      echo  Elite Knight       break

How to write a basic PHP Ternary Operator      your boolean     This is returned if true     This is returned if false     Example    myboolean   true  echo   myboolean     foobar     penguin   foobar  echo    myboolean     foobar     penguin   penguin   A PHP ternary operator with an  elseif  crammed in there    chow   3  echo   chow    1     one      chow    2     two     three   three   But please don t nest ternary operators except for parlor tricks   It s a bad code smell

To be honest  a ternary operator would only make this worse  what i would suggest if making it simpler is what you are aiming at is    groups   array 1  gt  Player   2  gt  Gamemaster   3  gt  God    echo  groups  result- gt group id      and then a similar one for your vocations   vocations   array    1  gt  Sorcerer     2  gt  Druid     3  gt  Paladin     4  gt  Knight             echo  vocations  result- gt vocation      With a ternary operator  you would end up with  echo  result- gt group id    1    Player      result- gt group id    2    Gamemaster      result- gt group id    3    God     unknown        Which as you can tell  only gets more complicated the more you add to it

A Ternary is not a good solution for what you want   It will not be readable in your code  and there are much better solutions available   Why not use an array lookup  map  or  dictionary   like so    vocations   array      1   gt   Sorcerer       2   gt   Druid       3   gt   Paladin               echo  vocations  result- gt vocation     A ternary for this application would end up looking like this   echo  result- gt group id    1    Player      result- gt group id    2    Gamemaster      result- gt group id    3    God     unknown        Why is this bad  Because - as a single long line  you would get no valid debugging information if something were to go wrong here  the length makes it difficult to read  plus the nesting of the multiple ternaries just feels odd   A Standard Ternary is simple  easy to read  and would look like this    value     condition     Truthy Value     Falsey Value     or  echo   some condition     The condition is true      The condition is false      A ternary is really just a convenient   shorter way to write a simple if else statement   The above sample ternary is the same as   if   some condition        echo  The condition is true      else       echo  The condition is false        However  a ternary for a complex logic quickly becomes unreadable  and is no longer worth the brevity   echo  result- gt group id    1    Player      result- gt group id    2    Gamemaster      result- gt group id    3    God     unknown        Even with some attentive formatting to spread it over multiple lines  it s not very clear   echo  result- gt group id    1         Player           result- gt group id    2             Gamemaster               result- gt group id    3                 God                  unknown

Since this would be a common task I would suggest wrapping a switch case inside of a function call   function getVocationName  vocation       switch  vocation           case 1  return  Sorcerer           case 2  return  Druid           case 3  return  Paladin           case 4  return  Knight           case 5  return  Master Sorcerer           case 6  return  Elder Druid           case 7  return  Royal Paladin           default  return  Elite Knight            echo getVocationName  result- gt vocation

You could also do   echo  yes      no     Assuming that yes is a variable that can be false    Instead of   echo  true      yes     no

I d rather than ternary if-statements go with a switch-case  For example   switch  result- gt vocation   case 1      echo  Sorcerer       break  case 2      echo  Druid       break  case 3      echo  Paladin       break  case 4      echo  Knight       break  case 5      echo  Master Sorcerer       break  case 6      echo  Elder Druid       break  case 7      echo  Royal Paladin       break  default      echo  Elite Knight       break
