What potential issue is identified with the use of multiple return statements in the PHP code?

Using multiple return statements in a PHP function can make the code harder to read and maintain. It can also lead to unexpected behavior if multiple return statements are reached during the execution of the function. To solve this issue, consider refactoring the code to have a single return statement at the end of the function, and use variables to store the return value if needed.

function calculateTotal($price, $quantity) {
    $total = $price * $quantity;
    
    // Perform additional calculations or checks here
    
    return $total;
}
