Subfolder permissions won't affect the permissions of newly created
files. For that, use umask:
http://us2.php.net/manual/en/function.umask.php
Run this and inspect the resulting permissions to get a feel for umask:
<?php
printf("My current umask is: %04o\n", umask());
umask(0077);
fopen("user_writable_only.txt", "w+");
umask(0007);
fopen("user_and_group_writable.txt", "w+");
umask(0000);
fopen("world_writable.txt", "w+");
?>
NB: In a real program, make sure you check the return values of fopen
and fwrite. Also, if you want to make sure a new file is being created
when you call fopen, use "x+" instead of "w+" for the second argument.
To change permissions on existing files, use chmod:
http://us2.php.net/manual/en/function.chmod.php
.
