Also if it is installed, in which directory?
And if in case some other package is installed, like lighttpd, where that is.
aptitude to start the package manager. There you can see which applications are installed.
/ to search for packages. Try searching for
php5 (or whatever versions you want to use). If they are installed, they should be bold and have an
i in front of them. If they are not installed (
p in front of the line) and you want to install them (and you have root permissions), use
+ to select them and then
g (twice) to install it.
Word of warning: Before doing that, it might be wise to have a quick look at some aptitude tutorial on the web.
