  <p>Everything works perfectly except the MSSQL driver for PHP. I have Googled a lot and downloaded lots of <code>dll</code> files. Every time I get this error:</p>
  
  <blockquote>
    <p>PHP Warning:  PHP Startup: Unable to load dynamic library c:\php\ext\php_sqlsrv_54_nts.dll - %1 is not a valid Win32 application.
     in Unknown on line 0</p>
  </blockquote>
  
  <p>Can anyone tell me that how can I find the specified driver? Thanks in advance.</p>
