Well I suggest that you either change your project to something that has more documentation out there to show you or look at the Crystal reports documentation and see if there is a way. Typically, if you are using PHP on windows, you can call the report using a com object... but there are little resources showing you code samples. I have found the following code out there, but not much more...
php
<?php
$crapp = new COM ("CrystalRuntime.Application") or die ("Error on
load");
$creport = $crapp->OpenReport("c:/test.rpt", 1);
$creport->ExportOptions->DiskFileName="c:/test.rtf";
$creport->ExportOptions->DestinationType=1; // Export to File
$creport->ExportOptions->FormatType=4; // Type: RTF
$creport->DiscardSavedData();
$creport->Export(false);
$creport = null;
$crapp = null;
print "...done";
?>
But if you have no clue on what this is all doing and how to get PHP running with it, you might want to switch topics now so that you are not pinned against a project that you can't end up completing.
Good luck and I hope it works out for you.
