How can the use of exit() affect the overall security and maintainability of PHP scripts?

The use of exit() in PHP scripts can affect security and maintainability because it abruptly terminates script execution, potentially leaving resources unclosed or data in an inconsistent state. To address this issue, it is recommended to refactor the code to use return statements instead of exit() to gracefully exit functions or methods without prematurely ending script execution. 

// Instead of using exit(), refactor the code to use return statements

function doSomething() {
    // do some operations
    return $result;
}

// Call the function
$result = doSomething();

// Continue script execution
// More code here
