To update an existing data attribute, you can combine `setData()` with `getData()`:

```php
$span->setData([
'data_attribute_1' => $span->getData('data_attribute_1', 0) + 1,
]);

$transaction->setData([
'data_attribute_1' => $transaction->getData('data_attribute_1', 0) + 1,
]);
```

To attach data attributes to the transaction and all its spans, you can use <PlatformLink to="/configuration/filtering/#using-before-send-transaction">`before_send_transaction`</PlatformLink>:

```php
\Sentry\init([
'dsn' => '___PUBLIC_DSN___',
'before_send_transaction' => function(Event $event) {
$spans = $event->getSpans();
foreach ($spans as $span) {
$span->setData([
'data_attribute_1' => 42,
'data_attribute_2' => true,
]);
}

$event->contexts['trace']['data']['foo'] = 42;
},
]);
```
