IBM Informix Icon IBM Informix ODBC Driver

The IBM Informix ODBC Driver is a powerful tool that allows you to connect with live data from IBM Informix, directly from any applications that support ODBC connectivity.

Access IBM Informix data like you would a database - read, write, and update IBM Informix databases through a standard ODBC Driver interface.

Access IBM Informix Data from MySQL in PHP



Connect to IBM Informix through the standard MySQL libraries in PHP.

You can use the CData SQL Gateway and ODBC Driver for IBM Informix to access IBM Informix data from MySQL clients, without needing to perform an ETL or cache data. Follow the steps below to connect to IBM Informix data in real time through PHP's standard MySQL interfaces, mysqli and PDO_MySQL.

Connect to IBM Informix Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

Set the following properties to connect to IBM Informix

  • Server: Set this to the name of the server running IBM Informix.
  • Port: Set this to the port the IBM Informix server is listening on.
  • Database: Set this to the name of the IBM Informix database.
  • User: Set this to the username of a user allowed to access the database.
  • Password: Set this to the password of a user allowed to access the database.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to IBM Informix data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

Creating a MySQL Remoting Service in SQL Gateway (Salesforce is shown)

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 "localhost" 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 on the SQL Gateway's Users tab.
  • Password: Specify the password for the authorized user account.
  • Database Name: Specify the system DSN as the database name.
  • Port: Specify the port the service is running on; port 3306 in this example.

mysqli

<?php
$mysqli = new mysqli("localhost", "user", "password", "CData Informix Sys","3306");
?>

PDO

<?php
$pdo = new PDO('mysql:host=localhost;dbname=CData Informix Sys;port=3306', 'user', 'password');
?>

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, Books. 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 = $mysqli->query("SELECT Id, Price FROM Books WHERE Category = 'US'");
while($row = $result->fetch_assoc()) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br>"; 
  }
}
$mysqli->close();

PDO

$result = $pdo->query("SELECT Id, Price FROM Books WHERE Category = 'US'");
while($row = $result->fetch(PDO::FETCH_ASSOC)) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br>"; 
  }
}
$result = null;
$pdo = null;
