Thank you very much for the information. As you expected PHP installed as an RPM in my server. If I found the "PHP mhash module" with the *SAME* version numbers of PHP, is that going to work with existing PHP(installed as RPM) ? Also, what kind of "PHP mhash module" should I look for? RPM or any other? Please help me in this regard. I need this urgenlty. Thanks again, --srinadh Srinadh Sannidhanam wrote: > I am trying to configure mhash. I installed mhash.

You probably have PHP installed as an RPM or some other kind of pre-packaged binary from your Linux distribution. You can either search for "PHP mhash module" with the *SAME* version numbers of PHP, or you can un-install the pre-packaged stuff and compile from source code. Had you compiled from source code, the "configure" part would be self-evident, as that is the first step in compiling from source code. It's also possible you are using Windows, in which case you need to search for a php_mhash.dll (or similar name) again from the *SAME* version, or you need to buy Visual C++ compiler and attempt (and probably not have much success for a long time) to compile PHP from source. Do *NOT* attempt to use an mhash Module unless you are 100% certain it was compiled with the same PHP version as what you have (see http://php.net/phpinfo). If you do attempt to do that, it might even "work" for awhile, but will cause huge problems sooner or later. -- Like Music? http://l-i-e.com/artists.htm --------------------------------- Do you Yahoo!?
