title: Install ingres extension for php on my WAMP server
body: <p>I've a development computer, which runs under windows.</p>
  
  <p>For a project, I've to make a php website which has to connect to an Ingres database server.</p>
  
  <p>So I installed wamp, I installed ingres(server and client, on my local machine).</p>
  
  <p>I added the library that I found on their site(<code>php_ingres.dll</code>) in the <code>C:\wamp\bin\php\php5.3.5\ext</code> folder, and I added a line "<code>extension=php_ingres.dll</code>" in the configuration file.</p>
  
  <p>I shutdown wamp and restarted it, and I restarted the server, I see now a check mark in the wamp menu, indicating that php_ingres is now activated. But when I go to the welcome page of the server, I don't see this extension as loaded. If I go on the php info page, I don't see any  Ingres entry in the Configure Command.</p>
  
  <p>I just can't found any <code>post/tutorial/...</code> which indicating how to do this operation, so any help would be appreciated!</p>
  
  <p>Thank you!</p>
  
  <p>Edit: I made a small test to see if I can connect to an Ingres database:</p>
  
  <pre><code>    &lt;?php
  $link = ingres_connect("localhost", "demodbtest", "demodbtest")  or die("Connexion impossible");
  echo "Connexion réussie";
  
  $result = ingres_query($link,"select * from airline");
  
  while ($row = ingres_fetch_array($result)) {
      echo $row["al_iatacode"];  // utilisation du tableau associatif
      echo $row["al_name"];
      echo $row["al_ccode"];          // utilisation du tableau à indices numériques
      echo "&lt;/br&gt;";
  }
  ingres_close($link);
  ?&gt;
  </code></pre>
  
  <p>And I get this error:</p>
  
  <blockquote>
    <p>( ! ) Fatal error: Call to undefined function ingres_connect() in
    C:\wamp\www\tests\index.php on line 2</p>
