How can error handling and debugging be improved in PHP code?

To improve error handling and debugging in PHP code, you can use functions like error_reporting() to set the level of error reporting, display_errors to show errors on the screen, and log_errors to log errors to a file. Additionally, you can use try-catch blocks to handle exceptions and use tools like Xdebug for more advanced debugging capabilities. 

// Set error reporting level
error_reporting(E_ALL);
ini_set('display_errors', 1);
ini_set('log_errors', 1);

// Example code with try-catch block
try {
    // Code that may throw an exception
    $result = 1 / 0;
} catch (Exception $e) {
    // Handle the exception
    echo 'Caught exception: ' . $e->getMessage();
}

// Example code with Xdebug
xdebug_start_trace();
// Code to debug
xdebug_stop_trace();
