There's a myriad of these things out there, of vastly varying quality.
Skewing away from PHP a tad, I looked at JasperReports a while back, when the mob I was working forw was about to embark down a hideously expensive CR / BO path.
Jasper is java, but might be worth some investigation - either because you know enough java to be useful, you're doing this for a large enough site that has some java resources available, or you are happy with the API as presented. There's also things like resin, quercus, and project zero (all things that give me the willies) that try to tie java with php - never looked at these, as I just don't move in java circles, or indeed at this level of application / integration work - but again might be of interest.
Much depends on what level of complexity / sophistication you want, and at what cost. As soon as someone starts talking about BO nee CR, I tend to assume they're in the $100k and up market.
EDIT: Oh, [url="http://en.wikipedia.org/wiki/Agata_Report"]Agata Report[/url] might be useful - they mention php, but presumably you've already found this one in your preliminary searches.
