PHP Ternary Operator

Ternary operator provides a short hand way of writing the if else statements block of codebook. It is represente by the question mark symbol (?) and it takes three operands: a condition to check, a result for true, and a result for false.

Syntax :

(Condition) ? (Statement1) : (Statement2);

Condition : Ternary operator is the expression to be evaluated and returns a boolean value.

Statement 1 : It is the statement to be executed if the condition results in a true block.

Statement 2 : It is the statement to be executed if the condition results in a false block.

how this Ternary operator works, consider the below examples :

Example :

<?php
    $age = 20;
    if($age < 18){
        echo 'Child'; // Display Child if age is less than 18
    } else{
        echo 'Adult'; // Display Adult if age is greater than or equal to 18
    }
?>

Using the PHP ternary operator same code could be written in a more compact way :

Example :

<?php
    $age = 20; 
    echo ($age < 18) ? 'Child' : 'Adult'; 
?>
