PHP Ternary Operator: When to Use It and When to Choose Alternatives?

How to Write a PHP Ternary Operator

The ternary operator in PHP is a concise syntax for writing conditional statements. It takes the form:

$result = (condition) ? value_if_true : value_if_false;

You can use this operator to write simple if-else statements, such as:

echo (true) ? "yes" : "no";    //prints yes
echo (false) ? "yes" : "no";    //prints no

However, the ternary operator does not support multiple conditions, such as "elseif" statements.

But wait, there's a solution! Instead of using a ternary operator, you can use a more readable alternative, such as an array lookup:

$vocations = array(
    1 => "Sorcerer",
    2 => "Druid",
    3 => "Paladin",
    ...
);

echo $vocations[$result->vocation];

This approach is more explicit and easier to maintain than using a nested ternary operator.

Remember: Ternary operators are useful for simple if-else statements, but for complex conditions, alternative solutions offer better readability and maintainability.
