How can PHP functions be utilized to improve script performance and output?

To improve script performance and output in PHP, functions can be utilized to encapsulate reusable blocks of code, reduce redundancy, and improve code organization. By breaking down the script into smaller, more manageable functions, it becomes easier to debug, maintain, and optimize the code. 

// Example of utilizing functions to improve script performance and output

// Function to calculate the sum of two numbers
function calculateSum($num1, $num2) {
    return $num1 + $num2;
}

// Function to display the result
function displayResult($result) {
    echo "The result is: " . $result;
}

// Usage of the functions
$number1 = 10;
$number2 = 20;

$sum = calculateSum($number1, $number2);
displayResult($sum);
