Natively Connect to Google Ads Data in PHP

The CData ODBC driver for Google Ads enables you to create PHP applications with connectivity to Google Ads data. Leverage the native support for ODBC in PHP.

Drop the CData ODBC Driver for Google Ads into your LAMP or WAMP stack to build Google Ads-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Google Ads 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.

Google uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

In addition to the OAuth values, specify the DeveloperToken and ClientCustomerId.

See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Establish a Connection

Open the connection to Google Ads by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.

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

Connections opened with odbc_connect are closed when the script ends. Connections opened with the odbc_pconnect 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.

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

Create Prepared Statements

Create prepared statements and parameterized queries with the odbc_prepare function.

$query = odbc_prepare($conn, "SELECT * FROM CampaignPerformance WHERE Device = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC GoogleAds Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM CampaignPerformance WHERE Device = ?"); $success = odbc_execute($query, array(''Mobile devices with full browsers''));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC GoogleAds Source","user","password"); $query = odbc_exec($conn, "SELECT Device, Clicks FROM CampaignPerformance");

Process Results

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

$conn = odbc_connect("CData ODBC Google Ads data Source","user","password"); $query = odbc_exec($conn, "SELECT Device, Clicks FROM CampaignPerformance"); while($row = odbc_fetch_array($query)){ echo $row["Device"] . "\n"; }

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

$conn = odbc_connect("CData ODBC Google Ads data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM CampaignPerformance WHERE Device = ?"); $success = odbc_execute($query, array(''Mobile devices with full browsers'')); 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 Ads-specific adaptations of the PHP community documentation for all ODBC functions.
