Security Issue Related to PHP Safe Mode

[billinchina]

I want to upload photos into a folder that is accessible to the world with file permissions 755. My php script only works when the permissions on the folder are 777. What can I do to make this safer? I'm running on a shared hosting account with php safe mode turned on (as always). I do not want to store the pics in a database, I just want to figure out some way to only allow my domain name or static ip to write to files and allow all others to read only.

what you could do is chmod the folder you right to 777 write the file

then chmod it back to 755

<?php
// Read and write for owner, nothing for everybody else
chmod("/somedir/somefile", 0600);

// Read and write for owner, read for everybody else
chmod("/somedir/somefile", 0644);

// Everything for owner, read and execute for others
chmod("/somedir/somefile", 0755);

// Everything for owner, read and execute for owner's group
chmod("/somedir/somefile", 0750);
?>

Can't use chmod function

It throws a warning cannot use error because the uid of the script is different that the file I'm trying to chmod. Probably need safe mode turned off for that too...
