Ben offered this example up for PHP access to the Oracle database from orchestra.

 $conn = OCILogon("guest","secret","testdb.world") or die("Couldn't connect"); 

 $query = "select user from dual";  

 $stmt = ociparse($conn, $query); 

 OCIDefineByName($stmt, "USER", $u); 

 ociexecute($stmt, OCI_DEFAULT); 

 ocifetch($stmt); 

 echo "The user is: $u"; 

 ocilogoff($conn);
