chmod dir - create dir inside - chmod dir back

[23style]

is it possable to chmod of a directory so you can create a directory inside with php, then once it is created, change the directory back so the public cannot write to it

1. dir = "home/test"
2. chmod test so you can create directory inside
3. create directory in test
4. chmod test back to 755

i cant seem to accomplish this, everytime i try to chmod it says chmod failed: Operation not permitted

am i missing something here?

any help is much appreciated 🙂

the existing dir is probably brought there by ftp.
so the dir owner is the ftp user

php is executed by another user (from "others", 3rd number)
hence you have to change the user of the dir to whatever the
user of php(apache) is, maybe "apache", "wwwrun" or "nobody"

(don't ask me how, I have no problem using 777 😉

if your webhoster has configured everything properly, it shouldn't be
a prob I guess)

p.s. now the apache user has only 5 = 4+1 = read+execute permissions, needs +2 = write, too)

i was using 777 before, but i get kind of paranoid about using it thinking about people being able to write to a dir. 😉
