My site is hosted by another provider. Is there a way I can tell if PEAR is installed on the server without having direct access to it?

how can I tell if PEAR is installed?

Assuming your machine has PEAR configured correctly and all is well the following should enlighten you as to if it is installed. Note though they may not have this package (PEAR_Info) installed... so you would prob get a fatal error... if your lucky provided by PEAR...if its installed :) - by the way when i checked this there was not docs for this package when i checked it (20th Oct 2003)... these are some of the main functions inside that class... along with

function setProxy($proxy)
function getPackages()
function getConfig()
function getCredits()
function pearImage() {
function show() {

<?php
// Include the appropriate PEAR classes
require_once("PEAR/Info.php");
$pearinfo = &new PEAR_Info();
$pearinfo->getPackages();
$pearinfo->getConfig();
$pearinfo->getCredits();
?>

I get an error when running getPackages()

Warning: Invalid argument supplied for foreach() in D:\xampplite\php\pear\PEAR\Info.php on line 235

Here's the whole script for packages, Line 235 is bold.

function getPackages()
{
$latest = @$this->r->call('package.listLatestReleases');
$available = $this->reg->listPackages();
if (PEAR::isError($available)) {
echo '<h1 style="font-size: 12px;">An Error occured fetching the package list. Please try again.</h1>';
return FALSE;
}
if (!is_array($available)) {
echo '<h1 style="font-size: 12px;">The package list could not be fetched from the remote server. Please try again.</h1>';
return FALSE;
}
natcasesort($available);
if ((PEAR::isError($latest)) || (!is_array($latest))) {
$latest = FALSE;
}
$packages = '';
foreach ($available as $name) {
$installed = $this->reg->packageInfo($name);
if (strlen($installed['package']) > 1) {

Please send response to tturowski@gmail.com also.

how can I tell if PEAR is installed?

You should have install driver for mysql

$dsn = 'mysql://test_user:test_pw@localhost/test_db';

simpleQuery is not in use right now, to launch the query simply use $dbobj->query() passing a query string in query function using above dsn.
