title: SAP and PHP Connection in WAMP server
body: <p>I have the following code:</p>
  
  <pre><code>&lt;?php
      include_once ("../libs/sap.php");
  
      $sap = new SAPConnection();
      // Params:                        hostname   sysnr
      $sap-&gt;ConnectToApplicationServer ("hostname", "sysnr");
      // Params:  client username  password  language
      $sap-&gt;Open ("client", "username","password","EN");
      $sap-&gt;PrintStatus();
      $sap-&gt;GetSystemInfo();
      echo "&lt;BR&gt;&lt;PRE&gt;"; print_r ($sap); echo ("&lt;/PRE&gt;");
      $sap-&gt;Close();
  ?&gt;
  </code></pre>
  
  <p>I have also add the dll in php/ext folder and change the php.ini file accordingly.</p>
  
  <p>DLL files are:</p>
  
  <p>1.php_saprfc_449.dll</p>
  
  <p>2.php_saprfc.dll</p>
  
  <p>3.php_saprfc_528.dll</p>
  
  <p>4.php_saprfc_528_nts.dll</p>
  
  <p>5.php_saprfc_530.dll</p>
  
  <p>6.php_saprfc_530_nts.dll</p>
  
  <p>7.php_sapnwrfc_x86.dll</p>
  
  <p>But I have got the message "SAPRFC extension is not installed. Exiting....".
  Please suggest me for the above</p>
  
  <p>Are any changes required in SAP to enable saprfc ?</p>
