Here are some examples of using attributes with the New Relic PHP agent. To use these settings:

1.  Modify your `newrelic.ini` file as applicable.
2.  Restart the agent and its daemon for changes to take effect.

## Capture request parameters [#ex_req_params]

By default, the agent does not capture request parameters.

You can use the following configuration to turn on parameter capture for these default destinations: `transaction_tracer`, `transaction_events`, and `error_collector`. If you want to limit the destinations that you capture parameters for, see [Selecting specific destinations](#example2).

**Configuration:**

```ini
newrelic.attributes.include = request.parameters.*
```

## Capture only specific request parameters [#ex_req_params_exclude]

To capture only specific request parameters, you can pass a list to `attributes.include`:

**Configuration**:

```ini
newrelic.attributes.include = request.parameters.user_id request.parameters.product_id
```

## Disabling all attributes [#example1]

In this example, attributes are disabled, so the include and exclude lists will be ignored and all attributes will be filtered out.

**Configuration:**

```ini
newrelic.attributes.enabled = false
newrelic.attributes.include = request.parameters.*
```

**Input keys:**

```
foo, bar, request.parameters.foo, request.parameters.bar
```

**Output for destinations:**

```
transaction_tracer: none
error_collector: none
transaction_events: none
browser_monitoring: none
```

## Selecting specific destinations [#example2]

In this example:

-   Attributes are disabled for transaction traces. The include and exclude lists will be ignored, and all attributes will be filtered out for this destination.
-   Attributes are also disabled for browser monitoring by default.
-   Request parameters (prefixed with `request.parameters.`) are off by default for all destinations.

As a result, only `bar` is sent in traced errors and transaction events.

**Configuration:**

```ini
newrelic.attributes.enabled = true
newrelic.transaction_tracer.attributes.enabled = false
newrelic.attributes.exclude = foo
```

**Input keys:**

```
foo, bar, request.parameters.foo, request.parameters.bar
```

**Output for destinations:**

```
transaction_tracer: none
error_collector: bar
transaction_events: bar
browser_monitoring: none
```

## Selecting values and destinations [#example3]

In this example, specific input keys are selected for certain output destinations and excluded from others.

-   The `food.fruit.banana` key will be excluded only from transaction traces.
-   The `food` and `food.bread` keys will be excluded from all destinations.

**Configuration:**

```ini
newrelic.browser_monitoring.attributes.enabled = true
newrelic.attributes.exclude = food*
newrelic.attributes.include = food.fruit.*
newrelic.transaction_tracer.attributes.exclude = food.fruit.banana
```

**Input keys:**

```
food, food.bread, food.fruit.banana, food.fruit.apple
```

**Output for destinations:**

```
transaction_tracer: food.fruit.apple
error_collector: food.fruit.banana, food.fruit.apple
transaction_events: food.fruit.banana, food.fruit.apple
browser_monitoring: food.fruit.banana, food.fruit.apple
```
