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";

    /*
