## Introduction to PEAR_Info

PEAR_Info obtains and displays information about your current PEAR Install. The PEAR_Info page features an A-Z index for easy searching, aswell as anchors for each package in the form of pkg_Package_Name (i.e. url.tld/pearinfo.php#pkg_PEAR_Info) PEAR_Info also features a full 'PEAR Credits' page, with information about the authors of the packages you currently have installed. PEAR_Info will also display any later versions that are available from PEAR to help keep you up to date.

Example 51-1. Using PEAR_Info
    <?php
        require_once 'PEAR/Info.php';

        /*
        If you need to set a http_proxy value at run-time you can use the
        following, this must be called BEFORE instantiating the PEAR_Info object
        */

        PEAR_Info::setProxy('your.proxy.here');

        /*
        Optional pear_dir variable, allows you to choose where your PEAR
        install is, in case its not found
        */

        $pear_dir = "/path/to/your/pear/files";

        /*
        Instantiate PEAR_Info object
        */

        $info = new PEAR_Info($pear_dir);

        /*
        Show PEAR_Info output
        */

        $info->show();
    ?>
