Natively Connect to DigitalOcean Data in PHP

The CData ODBC driver for DigitalOcean enables you to create PHP applications with connectivity to DigitalOcean data. Leverage the native support for ODBC in PHP.

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

DigitalOcean uses OAuth 2.0 authentication. To authenticate using OAuth, you can use the embedded credentials or register an app with DigitalOcean.

See the Getting Started guide in the CData driver documentation for more information.

Establish a Connection

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

$conn = odbc_connect("CData ODBC DigitalOcean 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.

$conn = odbc_pconnect("CData ODBC DigitalOcean Source","user","password"); ... odbc_close($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 Droplets WHERE Id = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC DigitalOcean Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Droplets WHERE Id = ?"); $success = odbc_execute($query, array('1'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC DigitalOcean Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Name FROM Droplets");

Process Results

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

$conn = odbc_connect("CData ODBC DigitalOcean data Source","user","password"); $query = odbc_exec($conn, "SELECT Id, Name FROM Droplets"); 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 DigitalOcean data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Droplets 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 DigitalOcean-specific adaptations of the PHP community documentation for all ODBC functions.
