Given three different numbers, the task is to find the Largest Number using Ternary Operator in PHP. In PHP, the ternary operator (?:) allows you to make a quick decision based on a condition. It is a shorthand method to write an if…else statement. You can use the ternary operator to find the largest number among two or more numbers.

Approach 1: Comparing Two Numbers

The simplest use case of the ternary operator is to compare two numbers and return the largest one.

<?php

$num1 = 10;
$num2 = 20;

$largest = ($num1 > $num2) ? $num1 : $num2;

echo "Largest Number: $largest";

?>

Largest Number: 20

In this example, if $num1 is greater than $num2, then $num1 is assigned to $largest; otherwise, $num2 is assigned.

Approach 2: Comparing Three Numbers

You can also use the ternary operator to compare three numbers and find the largest one.

<?php

$num1 = 10;
$num2 = 20;
$num3 = 15;

$largest = ($num1 > $num2) 
    ? ($num1 > $num3 ? $num1 : $num3) 
    : ($num2 > $num3 ? $num2 : $num3);

echo "Largest Number: $largest";

?>

Largest Number: 20

In this example, the outer ternary operator compares $num1 and $num2 first. If $num1 is greater, it compares $num1 with $num3 to determine the largest. If $num2 is greater, it compares $num2 with $num3 to determine the largest.
