From the command line it triggers a dialog box saying that the version of Crystal the reports was written in was later than the one that is being used to open it via the php program.   The other problem is that when it is run from the browser the program hangs on the openReport command

I use Crystal all day and via PHP also.

Here is the code I use (edited). It might not be perfect, but it works
perfectly.

<?php
// Create an Crystal Object Factory.
$o_CrObjectFactory = new COM('CrystalReports11.ObjectFactory.1');

// Create the Crystal Reports Runtime Application.
$o_CrApplication =
$o_CrObjectFactory->CreateObject("CrystalRunTime.Application.11");

// Register the typelibrary.
com_load_typelib('CrystalDesignRunTime.Application');

// Load the report.
$o_CrReport = $o_CrApplication->OpenReport('C:\Report.rpt', 1); // 1
== crOpenReportByTempCopy.

// Logon to the database.
$o_CrReport->Database->LogOnServer
	(
	'odbc',
	'Accounts',
	registryDatabaseLocations::Database('Accounts'),
	registryDatabaseLocations::Username('Accounts'),
	registryDatabaseLocations::Password('Accounts')
	);

// Don't tell anyone what is going on when running live.
$o_CrReport->DisplayProgressDialog = False;

$s_ExportedReport = 'C:\Report.pdf';

// Run the report and save the PDF to disk.
$o_CrReport->ExportOptions->DiskFileName = $s_ExportedReport;
$o_CrReport->ExportOptions->PDFExportAllPages = True;
$o_CrReport->ExportOptions->DestinationType = 1; // Export to File
$o_CrReport->ExportOptions->FormatType = 31; // 31 = PDF, 36 = XLS, 14 = DOC

// Assign the parameters to the report.
$m_Stuff = new Variant();

$o_CrPeriodsParam =
$o_CrReport->ParameterFields->GetItemByName('PeriodIDs', $m_Stuff);
$o_CrPeriodsParam->ClearCurrentValueAndRange();

foreach($_SESSION['tabRG_PeriodIDs'] as $i_Period)
	{
	$o_CrPeriodsParam->AddCurrentValue(intval($i_Period));
	}

$o_CrReport->ReadRecords();
$o_CrReport->Export(False);
?>
