The CData ODBC driver for Power BI XMLA enables you to create PHP applications with connectivity to Power BI XMLA data. Leverage the native support for ODBC in PHP.
Drop the CData ODBC Driver for Power BI XMLA into your LAMP or WAMP stack to build Power BI XMLA-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Power BI XMLA 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.
By default, use Azure AD to connect to Microsoft Power BI XMLA. Azure AD is Microsoft’s multi-tenant, cloud-based directory and identity management service. It is user-based authentication that requires that you set AuthScheme to AzureAD.
For more information on other authentication schemes, refer to the Help documentation.
Establish a Connection
Open the connection to Power BI XMLA by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.
$conn = odbc_connect("CData ODBC PowerBIXMLA 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.
$conn = odbc_pconnect("CData ODBC PowerBIXMLA Source","user","password");
...
odbc_close($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 Customer WHERE Country = ?");
Execute Queries
Execute prepared statements with odbc_execute.
$conn = odbc_connect("CData ODBC PowerBIXMLA Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Customer WHERE Country = ?");
$success = odbc_execute($query, array('Australia'));
Execute nonparameterized queries with odbc_exec.
$conn = odbc_connect("CData ODBC PowerBIXMLA Source","user","password");
$query = odbc_exec($conn, "SELECT Country, Education FROM Customer WHERE Country = 'Australia'");
Process Results
Access a row in the result set as an array with the odbc_fetch_array function.
$conn = odbc_connect("CData ODBC Power BI XMLA data Source","user","password");
$query = odbc_exec($conn, "SELECT Country, Education FROM Customer WHERE Country = 'Australia'");
while($row = odbc_fetch_array($query)){
echo $row["Country"] . "\n";
}
Display the result set in an HTML table with the odbc_result_all function.
$conn = odbc_connect("CData ODBC Power BI XMLA data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Customer WHERE Country = ?");
$success = odbc_execute($query, array('Australia'));
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 Power BI XMLA-specific adaptations of the PHP community documentation for all ODBC functions.
