This chapter requires that you are already familiar with the
general structure of PEAR.
The base installation that comes with the PHP distribution as part
of the PFC, contains all the stuff
that is needed to run the PEAR installation tools etc. If you have
a recent installation of PHP, you can relax: The PEAR base
installation is already there, unless you have compiled your PHP
with the ./configure flag
--without-pear.
The packages that are not part of the
PFC can be installed with the PEAR
package manager. The manager is comparable to Debian's
"apt-get". Again:
If you are running a recent version of PHP (> 4.3.0) you can skip
the next section. But if you are running PHP 4.2.* or earlier, you
need to manually install the manager.
Apart from installing packages, the PEAR package manager also
handles some other tasks: It can create new packages on your
machine, manage a registry of installed packages, check
dependencies and it can interact with an XML-RPC service on pear.php.net to serve
some other tasks.
