Natively Connect to TigerGraph Data in PHP


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

Drop the CData ODBC Driver for TigerGraph into your LAMP or WAMP stack to build TigerGraph-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to TigerGraph 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 authenticate with your TigerGraph instance, set the User, Password, and URL properties to valid TigerGraph credentials. By default connections are made on port 14240.

Establish a Connection

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

$conn = odbc_connect("CData ODBC TigerGraph 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.

$conn = odbc_pconnect("CData ODBC TigerGraph Source","user","password"); ... odbc_close($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 person WHERE locationId = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC TigerGraph Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM person WHERE locationId = ?"); $success = odbc_execute($query, array('chn'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC TigerGraph Source","user","password"); $query = odbc_exec($conn, "SELECT id, locationId FROM person WHERE locationId = 'chn'");

Process Results

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

$conn = odbc_connect("CData ODBC TigerGraph data Source","user","password"); $query = odbc_exec($conn, "SELECT id, locationId FROM person WHERE locationId = 'chn'"); 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 TigerGraph data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM person WHERE locationId = ?"); $success = odbc_execute($query, array('chn')); 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 TigerGraph-specific adaptations of the PHP community documentation for all ODBC functions.
