I have installed PHP with Microsoft Web PI. Then I installed mysql.
According to http://learn.iis.net/page.aspx/353/install-and-configure-mysql-for-php-applications-on-iis-7/
I have to Uncomment the following lines by removing the semicolon: extension=php_mysqli.dll extension=php_mbstring.dll extension=php_mcrypt.dll
But there is no extension=php_mcrypt.dll in php.ini installed by web PI so should I add it by hand then where ? and where should I check that php_mcrypt.dll exists ?
Seems nobody knows, should better ask on Microsoft forum ?
