# Function: project_from_id

Returns the project within a provided resource's id, resource URI, self link, or full resource name.

For more information about using provider-defined functions with Terraform [see the official documentation](https://developer.hashicorp.com/terraform/plugin/framework/functions/concepts).

## Example Usage

### Use with the `google` provider

```terraform
terraform {
  required_providers {
    google = {
      source = "hashicorp/google"
    }
  }
}

resource "google_pubsub_topic" "default" {
  project = "my-project"
  name    = "my-topic"
}

# Value is "my-project"
output "project_from_id" {
  value = provider::google::project_from_id(google_pubsub_topic.default.id)
}
```

### Use with the `google-beta` provider

```terraform
terraform {
  required_providers {
    google-beta = {
      source = "hashicorp/google-beta"
    }
  }
}

resource "google_pubsub_topic" "default" {
  # provider argument omitted - provisioning by google or google-beta doesn't impact this example
  project = "my-project"
  name    = "my-topic"
}

# Value is "my-project"
output "project_from_id" {
  value = provider::google-beta::project_from_id(google_pubsub_topic.default.id)
}
```
