I'm totally newbie to Linux, I just installed Linux Redhat 7.2 on my computer (server type) now I want to upgade PHP 4.2.1 to 4.2.2 but I cant find where PHP 4.2.1 is stored. Do you know where it is and by the way what is best way to upgrade PHP from 4.2.1 to 4.2.2

this may not be much help to u now, but when i install redhat, i set it up as a server, but dont install the webserver, ftp server and things like that

then once redhat is installed, i just go find them myself, that way, u dont have to go searching for where redhat has put them

This would be a good place to start - even if you are not running PSA.

get familiar with these commands:
locate
whereis
man (help pages on anything)
ex. man locate (will give you all options/syntax with command locate)
just find the php rpm for the distribution and upgrade like this
rpm -Uvh php4.2.2.rpm
