What best practice should be followed when testing PHP scripts?

When testing PHP scripts, it is important to follow best practices such as writing unit tests for each function, using a testing framework like PHPUnit, and ensuring proper error handling and logging. This helps to identify bugs and issues early on in the development process, leading to more reliable and maintainable code. 

// Example of a simple PHP script with proper error handling and logging

try {
    // Your PHP code here
} catch (Exception $e) {
    error_log('An error occurred: ' . $e->getMessage());
}
