Natively Connect to Omnisend Data in PHP

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

Start by setting the Profile connection property to the location of the Omnisend Profile on disk (e.g. C:\profiles\Omnisend.apip). Next, set the ProfileSettings connection property to the connection string for Omnisend (see below).

Omnisend API Profile Settings

Navigate to your Omnisend account integrations at https://app.omnisend.com/#/my-account/integrations/api-keys to generate an API key.

Establish a Connection

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

$conn = odbc_connect("CData ODBC API 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.

$conn = odbc_pconnect("CData ODBC API Source","user","password");
...
odbc_close($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 Batches WHERE Status = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Batches WHERE Status = ?");
$success = odbc_execute($query, array('completed'));
  

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_exec($conn, "SELECT BatchId, Method FROM Batches WHERE Status = 'completed'");
  

Process Results

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

$conn = odbc_connect("CData ODBC Omnisend data Source","user","password");
$query = odbc_exec($conn, "SELECT BatchId, Method FROM Batches WHERE Status = 'completed'");
while($row = odbc_fetch_array($query)){
 echo $row["BatchId"] . "\n";
}

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

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