Natively Connect to MailChimp Data 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, 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 or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC MailChimp 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.

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

Execute Queries

Execute prepared statements with .

$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 .

$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 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 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);
