Hello, I want to allow uploading of huge video files, which may be as big as 4 GB. But when I try to set post_max_size = 4G upload_max_filesize = 4G in php.ini, it doesn't work and everything in post (posted data) is ignored. I get a warning about size of posted data greater than some negative number. I read somewhere that php stores this data in integer. I have tested it on 64 bit system (php 5.1.6 installed on Mandriva 2007.0) as well as 32 bit system (php 5.2.2 installed on windows xp sp2). Value up to, I think, 2147483647 bytes or ( around 1.999.. gb) works We need to allow uploading of 4 GB files. Is there any solution. Regards, Sukhwinder Singh
