Natively Connect to Elorus Data in PHP

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

Start by setting the Profile connection property to the location of the Elorus Profile on disk (e.g. C:\profiles\Elorus.apip). Next, set the ProfileSettings connection property to the connection string for Elorus (see below).

Elorus API Profile Settings

Obtain your API Key from your User Profile in the top-right corner of Elorus. Find your Organization ID under Settings > Organization.

Establish a Connection

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

$conn = odbc_connect("CData ODBC API 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.

$conn = odbc_pconnect("CData ODBC API Source","user","password");
...
odbc_close($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 BillAttachments WHERE BillId = ?");

Execute Queries

Execute prepared statements with odbc_execute.

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM BillAttachments WHERE BillId = ?");
$success = odbc_execute($query, array('1'));
  

Execute nonparameterized queries with odbc_exec.

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_exec($conn, "SELECT BillId, Id FROM BillAttachments WHERE BillId = '1'");
  

Process Results

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

$conn = odbc_connect("CData ODBC Elorus data Source","user","password");
$query = odbc_exec($conn, "SELECT BillId, Id FROM BillAttachments WHERE BillId = '1'");
while($row = odbc_fetch_array($query)){
 echo $row["BillId"] . "\n";
}

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

$conn = odbc_connect("CData ODBC Elorus data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM BillAttachments WHERE BillId = ?");
$success = odbc_execute($query, array('1'));
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 Elorus-specific adaptations of the PHP community documentation for all ODBC functions.
