How does using the exit function in PHP affect output in scripts?

Using the exit function in PHP will immediately terminate the script and prevent any further output from being sent to the browser. This can be useful for stopping the script if a certain condition is met or for handling errors. However, it's important to note that using exit can also prevent any cleanup code or functions from running. 

// Example of using the exit function in PHP
$number = 10;

if ($number > 5) {
    echo "Number is greater than 5.";
    exit;
}

echo "This will not be outputted.";
