Re: move_uploaded_file locks?

Can't find this in the PHP docs, so: does anyone know whether move_uploaded_file locks the target file during the process? If move_uploaded_file does a rename within the same filesystem this isn't an issue (on unix, anyway, the O/S just reassigns inodes rather than copying data). But if it does a copy instead, or if it has to rename across filesystems, any process that tries to read or write the file before move_uploaded_file completes could be munging things.

I don't *think* it does any locking, it just calls the system functions to handle the rename (so yeh across partitions/file systems it will do a copy). The internals list might be able to give a more precise answer.. -- Postgresql & php tutorials http://www.designmagick.com/
