Opening a report with PHP code

I would like to know if Crystal Reports can be used with PHP. I have the following PHP code:

<?php
$reportToRun="C:\Program Files\EasyPHP1-8\www\trout\MyCustomer.rpt";
$crapp = new COM("CrystalRuntime.Application.10");
$creport = $crapp->OpenReport($reportToRun, 1);
?>

I get the following error:

Fatal error: Uncaught exception 'com_exception' with message 'Source: Crystal Reports ActiveX Designer
Description: Invalid directory.' in C:\Program Files\xampp\htdocs\xampp\crystal1.php:4 Stack trace: #0 C:\Program Files\xampp\htdocs\xampp\crystal1.php(4): com->OpenReport('C:\Program File...', 1) #1 {main} thrown in C:\Program Files\xampp\htdocs\xampp\crystal1.php on line 4

If I comment out the fourth line, where the report is being opened, I get no error message. My ultimate goal is to pass parameters to Crystal Reports, and have the user run the report from a web page. I am using Crystal Reports 10, Professional version. If this task is too much of a pain to accomplish using PHP, I am open to other technologies. Any suggestions will be appreciated. Thanks.
