+Here are the most commonly used values for setting permissions on directories and files.
+^directories^files^result^
+|0700|0600|read/write for owner only. Owner must be the same as the PHP process user.|
+|0770|0660|read/write for owner and group. The PHP process user needs to be in the user group|
+|0777|0666|read/write for everyone. Dangerous because everybody with access to the server may write and delete your files. Use only as a last resort on trusted machines, NOT on a cheap shared hosting server.|
