You need to install the mysql extension for PHP, hence the call to undefined function error. There should be more information about this in the Install file.

Thanx for your fast response
they suggest me to move libmysql.dll file to system folder i already copy this to system folder it still not working. i see all information regarding installetion in php.net but i can't find any solution. i think i should make some change on php.ini file or httpd of apache file but i don't know what should i change. or u can suggest me a local server software which support php and mysql.
my advance thanx to all who response on my problem.
