In what situations should one seek professional help or guidance when encountering PHP script errors?

When encountering PHP script errors that are difficult to diagnose or resolve on your own, it is advisable to seek professional help or guidance. This is especially true if the error is causing critical functionality issues on your website or application, or if you are unable to pinpoint the root cause of the problem despite troubleshooting efforts.

// Example PHP code snippet to implement a fix for a common PHP script error
try {
    // Your problematic code causing the error
} catch (Exception $e) {
    // Handle the error gracefully
    echo 'An error occurred: ' . $e->getMessage();
}
