Access USPS Data in PHP through the Cloud Hub

Connect to USPS through the standard MySQL libraries in PHP.

You can use the CData Cloud Hub to access USPS data from MySQL clients, without needing to perform an ETL or cache data. Follow the steps below to create a virtual MySQL database for USPS and connect to USPS 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 USPS, allowing you to easily query live USPS 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 USPS, leveraging server-side processing to quickly return USPS data.

Create a Virtual MySQL Database for USPS Data

You can use any MySQL client to connect to the CData Cloud Hub and create virtual databases.

  1. Connect to the CData Cloud Hub:
    mysql --host myinstance.cdatacloud.net --user admin --password
    
  2. Once authenticated, create the virtual database for USPS:
    mysql> CREATE DATABASE uspsdb
        -> DRIVER = "USPS",
        -> DBURL = "PostageProvider=ENDICIA; RequestId=12345; Password='abcdefghijklmnopqr'; AccountNumber='12A3B4C'";
    

With the virtual database created, you are ready to connect to USPS 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 USPS.
  • 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", "uspsdb",3306,NULL,MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT);
?>

PDO

<?php
$pdo = new PDO('mysql:host=myinstance.cdatacloud.net;dbname=uspsdb;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, Senders. 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 = $mysqli->query("SELECT FirstName, Phone FROM Senders WHERE SenderID = '25'");
while($row = $result->fetch_assoc()) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br />"; 
  }
}
$mysqli->close();

PDO

$result = $pdo->query("SELECT FirstName, Phone FROM Senders WHERE SenderID = '25'");
while($row = $result->fetch(PDO::FETCH_ASSOC)) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br />"; 
  }
}
$result = null;
$pdo = null;
