Access SAP Concur Data in PHP through the Cloud Hub

Connect to SAP Concur through the standard MySQL libraries in PHP.

You can use the CData Cloud Hub to access SAP Concur data from MySQL clients, without needing to perform an ETL or cache data. Follow the steps below to create a virtual MySQL database for SAP Concur and connect to SAP Concur data in real time through PHP's standard MySQL interfaces, mysqli and PDO_MySQL.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for SAP Concur, allowing you to easily query live SAP Concur data in PHP — without replicating the data to a natively supported database. As you query data in PHP, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to SAP Concur, leveraging server-side processing to quickly return SAP Concur data.

Create a Virtual MySQL Database for SAP Concur Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "SAP Concur" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to SAP Concur.

    SAP Concur uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId and OAuthClientSecret by registering an app with SAP Concur. See the Getting Started section of the help documentation for an authentication guide.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to SAP Concur data from any MySQL client.

Connect in PHP

The following examples show how to use object-oriented interfaces to connect and execute queries. Initialize the connection object with the following parameters to connect to the virtual MySQL database:

  • Host: Specify the remote host location where the service is running. In this case "myinstance.cdatacloud.net" is used for the remote host setting since the service is running on the local machine.
  • Username: Specify the username for a user you authorized in the Cloud Hub.
  • Password: Specify the password for the authorized user account.
  • Database Name: Specify the name of the virtual database you created for SAP Concur.
  • Port: Specify the port the service is running on, port 3306 in this example.

mysqli

<?php
$mysqli = mysqli_init();

$mysqli->ssl_set("C:/certs/cloudclient.key",
                 "C:/certs/cloudclient.pem",
                 "C:/certs/myCA.pem",
                 NULL,NULL);

$mysqli->real_connect("mysintance.cdatacloud.net", "admin", "mypassword", "concurdb",3306,NULL,MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT);
?>

PDO

<?php
$pdo = new PDO('mysql:host=myinstance.cdatacloud.net;dbname=concurdb;port=3306;','admin', 'mypassword', array(
    PDO::MYSQL_ATTR_SSL_KEY                => 'C:/certs/cloudclient.key',
    PDO::MYSQL_ATTR_SSL_CERT               => 'C:/certs/cloudclient.pem',
    PDO::MYSQL_ATTR_SSL_CA                 => 'C:/certs/myCA.pem',
    PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => false
    )
);
?>

Query in PHP

With the connection established, you can then access tables. The following steps walk through the example:

  1. Query the table; for example, Departments. The results will be stored as an associative array in the $result object.
  2. Iterate over each row and column, printing the values to display in the PHP page.
  3. Close the connection.

mysqli

$result = $mysqli->query("SELECT Id, OfficeId FROM Departments");
while($row = $result->fetch_assoc()) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br />"; 
  }
}
$mysqli->close();

PDO

$result = $pdo->query("SELECT Id, OfficeId FROM Departments");
while($row = $result->fetch(PDO::FETCH_ASSOC)) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br />"; 
  }
}
$result = null;
$pdo = null;
