Natively Connect to Salesforce Chatter Data in PHP

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

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

Salesforce Chatter uses OAuth 2.0 authentication. To authenticate to Salesforce Chatter via OAuth 2.0, you will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with Salesforce Chatter.

Establish a Connection

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

$conn = odbc_connect("CData ODBC SalesforceChatter 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.

$conn = odbc_pconnect("CData ODBC SalesforceChatter Source","user","password"); ... odbc_close($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 Users WHERE SearchTerms = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC SalesforceChatter Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Users WHERE SearchTerms = ?"); $success = odbc_execute($query, array('Smoked*BBQ'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC SalesforceChatter Source","user","password"); $query = odbc_exec($conn, "SELECT Name, PostCount FROM Users");

Process Results

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

$conn = odbc_connect("CData ODBC Salesforce Chatter data Source","user","password"); $query = odbc_exec($conn, "SELECT Name, PostCount FROM Users"); while($row = odbc_fetch_array($query)){ echo $row["Name"] . "\n"; }

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

$conn = odbc_connect("CData ODBC Salesforce Chatter data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Users WHERE SearchTerms = ?"); $success = odbc_execute($query, array('Smoked*BBQ')); 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 Salesforce Chatter-specific adaptations of the PHP community documentation for all ODBC functions.
