CData Connect Server

Access Yahoo! Data in PHP through Connect Server



Connect to Yahoo! through the standard SQL Server libraries in PHP.

You can use CData Connect Server to access Yahoo! data from SQL Server clients, without needing to perform an ETL or cache data. Follow the steps below to create a virtual SQL Server database for Yahoo! and connect to Yahoo! data in real time through PHP's standard SQL Server interface, i.e. sqlsrv_connect.

CData Connect Server provides a pure SQL Server interface for Yahoo!, allowing you to easily build reports from live Yahoo! data in PHP — without replicating the data to a natively supported database. As you build visualizations, PHP generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to Yahoo!, leveraging server-side processing to quickly return the requested Yahoo! data.

Create a Virtual SQL Server Database for Yahoo! Data

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

  1. Login to Connect Server and click Connections.
  2. Select "Yahoo!" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Yahoo!.

    In order to authenticate, specify the following:

    • AppID: The App ID used for authentication. Send a request to the Yahoo! Japan Data Solution support team to obtain your App ID.
    • (Optional) Search Keyword: Specify any value to search for.
  4. Click Save Changes
  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 Yahoo! data from PHP.

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 SQL Server database:

  • Server name/Host: Specify the remote host location where the service is running.
  • Username: Specify the username for a user you authorized in Connect Server.
  • Password: Specify the password for the authorized user account.
  • Database Name: Specify the name of the virtual database you created for Yahoo!.
  • Port: Specify the port the service is running on, port 1433 in this example.

sqlsrv_connect

<?php
$serverName = "connect_server_url, 1433"; //Connect Server Address, portNumber (default is 1433)
$connectionInfo = array( "Database"=>"YahooDS1", "UID"=>"userName", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo);

if( $conn ) {
     echo "Connection established.<br>";
}else{
     echo "Connection could not be established.<br>";
     die( print_r( sqlsrv_errors(), true));
}
?>

PDO

<?php
<?php
$user = my_connect_user
$pass = my_connect_pass

$pdo = new PDO("sqlsrv:Server=connect_server_url,1433;Database=YahooDS1", $user , $pass);

?>

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, SearchVolume. 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.

sqlsrv_connect

$result = $sqlsrv_connect->query("SELECT Date, Volume FROM SearchVolume WHERE SearchKeyword = 'CData'");
while($row = $result->fetch_assoc()) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br>"; 
  }
}
$sqlsrv_connect->close();

PDO

$result = $pdo->query("SELECT Date, Volume FROM SearchVolume WHERE SearchKeyword = 'CData'");
while($row = $result->fetch(PDO::FETCH_ASSOC)) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br>"; 
  }
}
$result = null;
$pdo = null;
