What are the potential risks of writing extremely long scripts in PHP?

Writing extremely long scripts in PHP can lead to decreased readability, maintainability, and performance issues. It can become difficult to debug and make changes to the code, leading to potential errors and inefficiencies. To mitigate these risks, it is recommended to break down the script into smaller, more manageable functions or classes. 

// Example of breaking down a long script into smaller functions

function processInput($input) {
    // code to process input
}

function validateInput($input) {
    // code to validate input
}

function generateOutput($data) {
    // code to generate output
}

$input = $_POST['input'];

$processedInput = processInput($input);
if (validateInput($processedInput)) {
    $output = generateOutput($processedInput);
    echo $output;
} else {
    echo "Invalid input";
}
