Hi,
Can anybody direct me to a URL that explains safe mode in php please?
Just the advantages / disadvantages of hosting with a host that has safe mode ON
I have tried google but very limited success and has left me more confused.
I really need to clarify this as the site I am making offers the users the options of
uploading their profile pictures and also deleteing their profile pictures.
Thanks!

Personal input: if you are running a shared server, safe mode is very useful for it helps to keep people working with only their files. it takes care of a lot of the things that could happen and hurt the server. i personally have found basically no instance where a user actually needed something disabled by safe mode. either there was another way to do this, or they shouldn't be doing it at all anyway.

Hey,
No problem about the double post.
I had actually visited both of those urls, but like i wrote, they just confused me.
What I want to know is if I can upload pictures via my script and then when i dont need them anymore unlink() them
same thing for mkdir and rmdir.
I was told that php creates the files using the servers uid and so it cannot unlink them later....true?
Thanks!
you can upload files and move them just fine, so long as the same user is doing it. deleting is the same: just needs to be the same user. you just have to make sure you are using the php functions to move the files and not any exec or shell_exec statements because exec and shell_exec are blocked.
you can basically do all file manipulation that you want within your directory.
If Apache runs as 'nobody', you may not be allowed to write files with CHMODing 777 the directory you want to write to. With safe mode on, this is not that large a security risk, if your host has shel access set up properly (other scripting languages, such as perl, may allow other users to write to that directory, however). You might just ftp the files to yourself as a workaround. I just wrote a little example of that in a tutorial I've been working on; you can have a look here if you're interested: http://www.nicholassolutio

an explanation of what all teh choices for the php.ini can be found at http://us2.php.net/feature
a more robust explanation can be found at http://docs.php.net/en/fea
if you scroll down, it explains and show examples for specific functions and such.
i hope that helps clarify.
