SolutionPHP needs to be set up to use it with MySQL.
To do that please open php.ini file in your C:Windows directory with a text editor, find the string

;extension=php_mysql.dll

and remove a semicolon from the beginning.
Then find the string beginning with

;extension_dir =

and make sure that this points to folder within your PHP installation where php_mysql.dll file resides. Usually it is "c:phpextensions"
And at last copy libmysql.dll from your MySQL installation into the C:WindowsSystem32 directory.
