How can PHP beginners effectively handle error output and debugging in their code?

PHP beginners can effectively handle error output and debugging in their code by using error reporting functions like error_reporting() and ini_set('display_errors', 1) to display errors on the screen. They can also use functions like var_dump() and print_r() to print out variable values for debugging purposes. Additionally, utilizing try-catch blocks can help catch and handle exceptions gracefully. 

// Set error reporting to display all errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Sample code with error handling and debugging
try {
    $numerator = 10;
    $denominator = 0;
    
    if($denominator == 0) {
        throw new Exception("Division by zero error");
    }
    
    $result = $numerator / $denominator;
    echo "Result: " . $result;
} catch(Exception $e) {
    echo "Error: " . $e->getMessage();
}
