You can download and use it for free. But don't delete the copyright notice. You can read terms of the PHP license.

YES if there is no answer in this Guide and if you are ready to share some informations such as : your configuration (platform Win *nix mac, PHP version, PEAR packages installed) and perharps your script.

You can report it with the bug tracker at PEAR.

PEAR (an acronym for PHP Extension and Application Repository) is a framework and distribution system for reusable PHP components.

Don't forget to read also the PEAR Manual and PEAR FAQ.

If your system file (see command pear config-show) does not exists, or is locate in another directory, then you should give this information on PEAR_Info class constructor.

<?php
// @link http://pear.php.net/bugs/bug.php?id=12878
//       Search for pear.conf inside /etc/pear/

require_once 'PEAR/Info.php';

$pear_dir  = '';
$user_file = '';
$syst_file = '/etc/pear/pear.conf';

$info = new PEAR_Info($pear_dir, $user_file, $syst_file);
$info->display();
?>

First copy the default stylesheet named pearinfo.css (locate in {data_dir}/PEAR_Info : see command pear config-show) as a pattern. Then second, change colors and whatever you want until you keep all CSS selectors.

See for example the blue layout pattern skin locate in package installation under name {doc_dir}/PEAR_Info/examples/blueskin.css.

Last, as {doc_dir}/PEAR_Info/examples/pear_info2.php script, set the new stylesheet with PEAR_Info::setStyleSheet.

<?php
require_once 'PEAR/Info.php';

$info = new PEAR_Info();
$info->setStyleSheet(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'blueskin.css');
$info->display();
?>

By default PEAR_Info display only informations from pear.php.net channel.

To remove this limit, give as option to the class constructor an empty channels list, as below :

<?php
require_once 'PEAR/Info.php';

$pear_dir  = '';
$user_file = '';
$syst_file = '/opt/lampp/etc/pear.conf';
$options   = array('channels' => array() );

$info = new PEAR_Info($pear_dir, $user_file, $syst_file, $options);
$info->display();
?>

With static method PEAR_Info::packageInstalled, you can check installation of a package from all channels declared, and also filter by version.

<?php
require_once 'PEAR/Info.php';

$inst = PEAR_Info::packageInstalled('Role_Web', '1.1.0', 'pearified');
if ($inst === false) {
    echo 'sorry it seems that "pearified/Role_Web" package is not installed'
       . ' or version is less than 1.1.0';
}
?>
