Natively Connect to MailChimp Data in PHP

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

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

You can set the APIKey to the key you generate in your account settings, or, instead of providing your APIKey, you can use the OAuth standard to authenticate the application. OAuth can be used to enable other users to access their own data. To authenticate using OAuth, you will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with MailChimp.

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

Establish a Connection

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

$conn = odbc_connect("CData ODBC MailChimp 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.

$conn = odbc_pconnect("CData ODBC MailChimp Source","user","password"); ... odbc_close($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 Lists WHERE Contact_Country = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC MailChimp Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Lists WHERE Contact_Country = ?"); $success = odbc_execute($query, array('US'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC MailChimp Source","user","password"); $query = odbc_exec($conn, "SELECT Name, Stats_AvgSubRate FROM Lists");

Process Results

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

$conn = odbc_connect("CData ODBC MailChimp data Source","user","password"); $query = odbc_exec($conn, "SELECT Name, Stats_AvgSubRate FROM Lists"); while($row = odbc_fetch_array($query)){ echo $row["Name"] . "\n"; }

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

$conn = odbc_connect("CData ODBC MailChimp data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Lists WHERE Contact_Country = ?"); $success = odbc_execute($query, array('US')); 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 MailChimp-specific adaptations of the PHP community documentation for all ODBC functions.
