How can PHP error handling be improved to troubleshoot issues with database queries and result processing?

When troubleshooting database query and result processing issues in PHP, it is important to implement proper error handling to identify and resolve any issues that may arise. One way to improve PHP error handling in this scenario is by using try-catch blocks to catch exceptions thrown during database operations and result processing, and then displaying meaningful error messages to aid in debugging. 

try {
    // Database connection code
    $db = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    
    // Database query code
    $query = $db->prepare("SELECT * FROM mytable");
    $query->execute();
    
    // Result processing code
    while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
        // Process the result
    }
} catch (PDOException $e) {
    // Display error message
    echo "Error: " . $e->getMessage();
}
