PDO MySQL PHP8 PHP

I'm dealing with Could someone explain I'm working with an unexpected `SQLSTATE[HY000]: General behavior: 1366 Incorrect integer value: '' for column 'age' at row 1` when trying to insert data into my MySQL database using PDO in PHP 8.0... My form collects user data, including their age, which is an integer. Here's a snippet of my code: ```php try { $pdo = new PDO('mysql:host=localhost;dbname=mydb', 'user', 'password'); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $stmt = $pdo->prepare('INSERT INTO users (name, age) VALUES (:name, :age)'); $stmt->bindParam(':name', $name); $stmt->bindParam(':age', $age); $name = 'John Doe'; $age = ''; $stmt->execute(); } catch (PDOException $e) { echo 'behavior: ' . $e->getMessage(); } ``` I've checked that the age field in the database is set to `INT`. I also verified that the form is submitting the age correctly, but I'm explicitly setting `age` as an empty string (`''`) in the code, which I thought would be handled as `NULL`. However, it's causing the query to unexpected result. I tried adding a check before the bind to convert the empty string to `null` like this: ```php $age = $age === '' ? null : $age; ``` However, I still receive the same behavior. Is there a better way to handle this situation? Should I be validating the input at the form level or is there a different approach I should take with my PDO statements? Any insights would be appreciated! I'm working on a application that needs to handle this. What's the best practice here? The stack includes Php and several other technologies. Thanks in advance! I'd really appreciate any guidance on this. I'm developing on Ubuntu 22.04 with Php.
