How does the ternary operator work in PHP and when should it be used?

The ternary operator in PHP is a shorthand way of writing an if-else statement. It is used when you need to assign a value to a variable based on a condition. The syntax is: condition ? value_if_true : value_if_false. This can make your code more concise and easier to read in certain situations.

// Example of using the ternary operator to assign a value based on a condition
$score = 85;
$result = ($score >= 70) ? "Pass" : "Fail";

echo $result; // Output: Pass
