If you want to change the permissions of an existing file, use chmod (change mode):

$itWorked = chmod ("/yourdir/yourfile", 0777);

If you want all new files to have certain permissions, you need to look into setting your umode. This is a process setting that applies a default modification to standard modes.

It is a subtractive one. By that, I mean a umode of 022 will give you a default permission of 755 (777 - 022 = 755).

But you should think very carefully about both these options. Files created with that mode will be totally unprotected from changes.
