Natively Connect to Google Translate Data in PHP

Drop the CData ODBC Driver for Google Translate into your LAMP or WAMP stack to build Google Translate-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Google Translate data, execute queries, and output the results.

Configure a DSN

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Authentication

Google Cloud Translation API requires OAuth 2.0 authentication to ensure secure access to translation services, datasets, glossaries, and adaptive MT resources. This authentication method allows you to securely connect to your Google Cloud project and manage translation resources with proper authorization.

OAuth 2.0 Setup and Configuration

Step 1: Create Google Cloud Project and Enable API

To set up OAuth authentication:

1. Visit the Google Cloud Console
2. Create a new project or select an existing project
3. Note down your Project ID (required for all API calls)
4. Navigate to "APIs & Services" > "Library"
5. Search for and enable the "Cloud Translation API"
6. Go to "APIs & Services" > "Credentials"
7. Click "Create Credentials" and select "OAuth Client ID"
8. Configure the OAuth consent screen if prompted
9. Select "Desktop application" or "Web application" as appropriate
10. Set the authorized redirect URI (CallbackURL)
11. Copy the Client ID and Client Secret for use in your connection

Required Connection Properties

• AuthScheme: Set this to OAuth (required)
• OAuthClientId: Client ID from Google Cloud Console (required)
• OAuthClientSecret: Client secret from Google Cloud Console (required)
• CallbackURL: Redirect URI specified in your OAuth application (required)
• InitiateOAuth: Set to GETANDREFRESH for automatic token management (recommended)
• ProjectId: Your Google Cloud project ID or project number (required for queries)

Required OAuth Scopes

The Google Cloud Translation API Profile requires the following OAuth scope:

• https://www.googleapis.com/auth/cloud-translation - Full access to Cloud Translation API resources including translation, datasets, glossaries, and adaptive MT

Establish a Connection

Open the connection to Google Translate by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC API Source","user","password");

Connections opened with are closed when the script ends. Connections opened with the method are still open after the script ends. This enables other scripts to share that connection when they connect with the same credentials. By sharing connections among your scripts, you can save system resources, and queries execute faster.

$conn = odbc_pconnect("CData ODBC API Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly

Create Prepared Statements

Create prepared statements and parameterized queries with the function.

$query = odbc_prepare($conn, "SELECT * FROM SupportedLanguages WHERE ProjectId = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM SupportedLanguages WHERE ProjectId = ?");
$success = odbc_execute($query, array('my-project-12345'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_exec($conn, "SELECT LanguageCode, DisplayName FROM SupportedLanguages WHERE ProjectId = 'my-project-12345'");
 

Process Results

Access a row in the result set as an array with the function.

$conn = odbc_connect("CData ODBC Google Translate data Source","user","password");
$query = odbc_exec($conn, "SELECT LanguageCode, DisplayName FROM SupportedLanguages WHERE ProjectId = 'my-project-12345'");
while($row = odbc_fetch_array($query)){
 echo $row["LanguageCode"] . "\n";
}

Display the result set in an HTML table with the function.

$conn = odbc_connect("CData ODBC Google Translate data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM SupportedLanguages WHERE ProjectId = ?");
$success = odbc_execute($query, array('my-project-12345'));
if($success)
 odbc_result_all($query);

More Example Queries

You will find complete information on the driver's supported SQL in the help documentation. The code examples above are Google Translate-specific adaptations of the PHP community documentation for all ODBC functions.
