## Description

These samples show how to use the [Google Cloud Translate API][translate-api]
from PHP.

[translate-api]: https://cloud.google.com/translate/docs/quickstart-client-libraries

## Build and Run
1.  **Enable APIs** - [Enable the Translate API](https://console.cloud.google.com/flows/enableapi?apiid=translate)
    and create a new project or select an existing project.
2.  **Download The Credentials** - Configure your project using [Application Default Credentials][adc].
    Click "Go to credentials" after enabling the APIs. Click "Create Credentials"
    and select "Service Account Credentials" and download the credentials file. Then set the path to
    this file to the environment variable `GOOGLE_APPLICATION_CREDENTIALS`:
```
    $ export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
```
3.  **Clone the repo** and cd into this directory
```
    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples
    $ cd php-docs-samples/translate
```
4.  **Install dependencies** via [Composer](http://getcomposer.org/doc/00-intro.md).
    Run `php composer.phar install` (if composer is installed locally) or `composer install`
    (if composer is installed globally).
5.  **Run** with the command `php src/SNIPPET_NAME.php`. For example:
    ```sh
    $ php src/list_languages.php
    af: Afrikaans
    sq: Albanian
    am: Amharic
    ...

    $ php src/translate.php "This is my text to translate" fr
    Source language: en
    Translation: Ceci est mon texte à traduire
    ```
