How can error handling be improved in the PHP code to identify the specific issue with inserting data into the database?

The issue with error handling in the PHP code for inserting data into the database is that it lacks specificity in identifying the root cause of the problem. To improve error handling, we can utilize PHP's `try-catch` block to catch exceptions thrown during the database operation and then use the `getMessage()` method to retrieve the specific error message.

try {
    // Database connection and data insertion code here
    $conn = new PDO("mysql:host=localhost;dbname=myDB", $username, $password);
    $stmt = $conn->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
    $stmt->bindParam(':value1', $value1);
    $stmt->bindParam(':value2', $value2);
    $stmt->execute();
} catch (PDOException $e) {
    echo "Error: " . $e->getMessage();
}
