Natively Connect to WordPress Data in PHP
The CData ODBC driver for WordPress enables you to create PHP applications with connectivity to WordPress data. Leverage the native support for ODBC in PHP.
Drop the CData ODBC Driver for WordPress into your LAMP or WAMP stack to build WordPress-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to WordPress 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 WordPress, set the URL property and other authentication properties. WordPress supports Basic (User and Password) and OAuth2.0 authentication, though Basic is recommended for a testing environment only. To connect with OAuth you will need to register an app with WordPress.
See the Getting Started guide in the CData driver documentation for more information.
Establish a Connection
Open the connection to WordPress by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.
$conn = odbc_connect("CData ODBC WordPress 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.
$conn = odbc_pconnect("CData ODBC WordPress Source","user","password");
...
odbc_close($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 Categories WHERE Id = ?");
Execute Queries
Execute prepared statements with odbc_execute.
$conn = odbc_connect("CData ODBC WordPress Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Categories WHERE Id = ?");
$success = odbc_execute($query, array('1'));
Execute nonparameterized queries with odbc_exec.
$conn = odbc_connect("CData ODBC WordPress Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Categories");
Process Results
Access a row in the result set as an array with the odbc_fetch_array function.
$conn = odbc_connect("CData ODBC WordPress data Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Categories");
while($row = odbc_fetch_array($query)){
echo $row["Id"] . "\n";
}
Display the result set in an HTML table with the odbc_result_all function.
$conn = odbc_connect("CData ODBC WordPress data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Categories WHERE Id = ?");
$success = odbc_execute($query, array('1'));
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 WordPress-specific adaptations of the PHP community documentation for all ODBC functions.

Wordpress ODBC Driver
The Wordpress ODBC Driver is a powerful tool that allows you to connect with live data from Wordpress, directly from any applications that support ODBC connectivity.
Access Wordpress data like you would a database - read, write, and update Wordpress Pages, Posts, Tags, Users, etc. through a standard ODBC Driver interface.
