Natively Connect to Amazon Marketplace Data in PHP

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

To connect to the Amazon Marketplace Webservice (MWS), AWSAccessKeyId, MWSAuthToken, AWSSecretKey and SellerId are required. You can optionally set the Marketplace property. For more information on obtaining values for these properties, refer to the Help documentation.

Establish a Connection

Open the connection to Amazon Marketplace by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC AmazonMarketplace 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.

$conn = odbc_pconnect("CData ODBC AmazonMarketplace Source","user","password");
...
odbc_close($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 Orders WHERE IsReplacementOrder = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC AmazonMarketplace Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE IsReplacementOrder = ?");
$success = odbc_execute($query, array('True'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC AmazonMarketplace Source","user","password");
$query = odbc_exec($conn, "SELECT AmazonOrderId, OrderStatus FROM Orders WHERE IsReplacementOrder = True");
 

Process Results

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

$conn = odbc_connect("CData ODBC Amazon Marketplace data Source","user","password");
$query = odbc_exec($conn, "SELECT AmazonOrderId, OrderStatus FROM Orders WHERE IsReplacementOrder = True");
while($row = odbc_fetch_array($query)){
 echo $row["AmazonOrderId"] . "\n";
}

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

$conn = odbc_connect("CData ODBC Amazon Marketplace data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE IsReplacementOrder = ?");
$success = odbc_execute($query, array('True'));
if($success)
 odbc_result_all($query);
