When you upgrade Zend Server, you often replace some of the directories that will be given new permissions in this exercise. And when you do a clean install or install a new version that you need to migrate to, again there will be all new directories without these permissions. In these cases, you will need to redo the steps in this article to provide the needed permissions. So, it is important to keep notes on the permissions set so you can go back and do this again when needed. You could even create a CL program to do this task for you and run it whenever needed. |

It can be more convenient to simply run the above commands for user *PUBLIC. This would allow any user successfully signed in with valid credentials to use PHP scripts run via php-cli. However, this is generally considered less secure than specifying allowed users individually.
Users with the *ALLOBJ special authority do not need to have permissions granted in order to run scripts using php-cli. Sometimes a developer will not have any problem running scripts in php-cli, but will discover that the users in production are having permissions problems. This is usually because the developer has *ALLOBJ special authority, while typical users in production do not.
