How can beginners ensure proper error handling in PHP scripts to avoid white screen errors?

When writing PHP scripts, beginners can ensure proper error handling by using try-catch blocks to catch and handle exceptions. This helps prevent white screen errors by providing a way to gracefully handle errors and display meaningful error messages to users. By using try-catch blocks, beginners can easily identify and troubleshoot issues in their scripts.

try {
    // PHP code that may throw an exception
} catch (Exception $e) {
    echo 'An error occurred: ' . $e->getMessage();
}
