Please help! Oracle + PHP question

Hello! I`ve got a problem, witch made me a bit sad, and mad :) So, the problem is about BLOB, uploading file, and so on... And when ive seeked for the solution, ive found many other people with the same problem... So this is it: When i try to use a script nearly the same as it shown in your manual in php.net/manual/function.ocinewdescriptor.php 2nd example. So as you can see, i just want to upload a file into a BLOB. And it doesn`t work :( It returns a warning :OCILobWrite: ORA-22990: LOB locators cannot span transactions in ... in the line, where i try to use savefile() function of a lob object created several lines before. So i ask you to give me a _working_ example, if it is possible. Thank you for your help! NemTom
