title: Add writing permission to PHP on IIS 7
body: <p>I need a PHP script to have writing permission in a directory. PHP 5.3 is running as FastCGI under IIS 7 with windows server 2008 as OP. On my php error logs, I got "permission denied" when the script attempts to write a file.</p>
  
  <p>How can I sort this out? I tried to give all right to IIS_IUSR and to IUSR_myservername (with a right click on my folder) but it didn't work.</p>
  
  <p>Any help would be very appreciate,</p>
  
  <p>Regards,</p>
