Natively Connect to Sybase Data 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 connect to Sybase, specify the following connection properties:

• Server: Set this to the name or network address of the Sybase database instance.
• Database: Set this to the name of the Sybase database running on the specified Server.

Optionally, you can also secure your connections with TLS/SSL by setting UseSSL to true.

Sybase supports several methods for authentication including Password and Kerberos.

Connect Using Password Authentication

Set the AuthScheme to Password and set the following connection properties to use Sybase authentication.

• User: Set this to the username of the authenticating Sybase user.
• Password: Set this to the username of the authenticating Sybase user.

Connect using LDAP Authentication

To connect with LDAP authentication, configure Sybase server-side to use the LDAP authentication mechanism.

After configuring Sybase for LDAP, you can connect using the same credentials as Password authentication.

Connect Using Kerberos Authentication

To leverage Kerberos authentication, begin by enabling it setting AuthScheme to Kerberos. See the Using Kerberos section in the Help documentation for more information on using Kerberos authentication.

You can find an example connection string below:

Server=MyServer;Port=MyPort;User=SampleUser;Password=SamplePassword;Database=MyDB;Kerberos=true;KerberosKDC=MyKDC;KerberosRealm=MYREALM.COM;KerberosSPN=server-name

Establish a Connection

Open the connection to Sybase by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC Sybase Source","user","password");

Connections opened with are closed when the script ends. Connections opened with the 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 function.

$query = odbc_prepare($conn, "SELECT * FROM Products WHERE ProductName = ?");

Execute Queries

Execute prepared statements with .

$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 .

$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 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 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.
