Natively Connect to Sybase Data in PHP

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

Drop the CData ODBC Driver for Sybase into your LAMP or WAMP stack to build Sybase-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Sybase 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 Sybase, set User and Password. Additionally, set IntegratedSecurity; to true to use Windows authentication otherwise, Sybase authentication is used. Set the Server and Database properties. To secure connections with TLS/SSL, set Encrypt to true.

Establish a Connection

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

$conn = odbc_connect("CData ODBC Sybase 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.

$conn = odbc_pconnect("CData ODBC Sybase Source","user","password"); ... odbc_close($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 Products WHERE ProductName = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC Sybase Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Products WHERE ProductName = ?"); $success = odbc_execute($query, array('Konbu'));

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC Sybase Source","user","password"); $query = odbc_exec($conn, "SELECT Id, ProductName FROM Products WHERE ProductName = Konbu");

Process Results

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

$conn = odbc_connect("CData ODBC Sybase data Source","user","password"); $query = odbc_exec($conn, "SELECT Id, ProductName FROM Products WHERE ProductName = Konbu"); 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 Sybase data Source","user","password"); $query = odbc_prepare($conn, "SELECT * FROM Products WHERE ProductName = ?"); $success = odbc_execute($query, array('Konbu')); 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 Sybase-specific adaptations of the PHP community documentation for all ODBC functions.
