    Evaluating If Else statements is very common in programming paradigm. But 'If Else' statements are long and they can be easily replaced by simply using Ternary operators. Here is a tutorial on the usage of ternary operators and their implementation in Php.

    The ternary operator logic -

    (condition) ? (true return value) : (false return value)

    If condition is true execute the true block and if false then execute the false block

     /* Simple usage */
     $a = 2;  
     $a_is_greater_than_one = ($a > 1 ? true : false); // returns true
    

    Advantages of implementing Ternary Logic :-

    If/Else logic can be coded quicker

    Short code

    Code maintenace is easy

    More Sample Usage

        /* Basic usage */
    
    $message = 'Hello '.($user->is_logged_in() ? $user->get('first_name') : 'Guest');
    // If user is logged in then print Hello 'name' else  print the name of user as guest
    
    
     /* echo, inline */
    echo 'On the basis of your score, you are ',($score > 90 ? 'a genius' : 'not a genius'); 
    // If you're score is greater than 90 then you are a genius else you are not a genius
    
    
    
    /* Next level */
    $days = ($month == 2 ? ($year % 4 ? 28 : ($year % 100 ? 29 : ($year %400 ? 28 : 29))) : (($month - 1) % 7 % 2 ? 30 : 31));  //returns days in the given month
