PHP Program to Conditional or Ternary Operators

Here's an example PHP program that demonstrates the use of conditional or ternary operators :

Program :

<?php

$a = 10;
$b = 5;

// Ternary operator
$max = ($a > $b) ? $a : $b;
echo "The maximum value is: $max <br>";

// Nested ternary operator
$result = ($a > 0) ? (($b > 0) ? "Both numbers are positive" : "Only $a is positive") : "Neither number is positive";
echo "Result: $result <br>";

?>

Output :

The maximum value is: 10
Result: Both numbers are positive

In this example, we have declared two variables `$a` and `$b` and assigned them the values `10` and `5`, respectively. We then use the ternary operator to determine the maximum value of `$a` and `$b`.

We also use a nested ternary operator to check if both `$a` and `$b` are positive, only `$a` is positive, or neither number is positive.

Finally, we print out the results using the `echo` statement.
