Thanks for help.
But unfortunately I am not able to execute any mssql_ functions (the error was 'undefined funtion...') for that (on the suggestion of a friend),
->I downloaded php-4.0.6-Win32.zip
->extracted it to c:\PHP folder
->copied php.ini-dist to windows directory and renamed it to php.ini (i.e. replaced the existing php.ini) and then to that php.ini made following changes:
-> uncommented, extension=php_gd.dll
-> Added, extension_dir = c:\php\extensions
Then when I run the program,
-> Still its working
-> But not throwing any error even
Thanks in advance
