What alternative approach, such as using functions, could the user consider to manage variable scope in PHP?

When dealing with variable scope in PHP, one alternative approach is to encapsulate variables within functions. By defining variables within functions, you can limit their scope to that specific function, preventing conflicts with variables in other parts of your code. This can help organize and manage your variables more effectively. 

function myFunction() {
    $localVariable = "This is a local variable.";
    echo $localVariable;
}

myFunction(); // Output: This is a local variable.

// Attempting to access $localVariable outside of the function will result in an error
// echo $localVariable; // This will throw an error
