• PHP MySQL Zend-ACL - Find all inherited items (Children / Parents)

  - by Scoobler

  I have one MySQL DB table like the following, the resources table: id | name | type 1 | guest | user 2 | member | user 3 | moderator | user 4 | owner | user 5 | admin | user 6 | index | controller Onto the next table, the rules table: id | user_id | rule | resource_id | extras 1 | 2 | 3 | 1 | null 2 | 3 | 3 | 2 | null 3 | 4 | 3 | 3 | null 4 | 5 | 3 | 4 | null 5 | 6 | 1 | 1 | index,login,register 6 | 6 | 2 | 2 | login,register 7 | 6 | 1 | 2 | logout OK, sorry for the length, but I am trying to give a full picture of what I am trying to do. So the way it works, a role (aka user) can be granted (rule: 1) access to a controller, a role can inherit (rule: 3) access from another role or a role and be denied (rule: 2) access to a controller. (A user is a resource and a controller is a resource) Access to actions are granted / denied using the extras column. This all works, its not a problem with setting up the ACL within zend. What I am now trying to do is show the relationships; to do that I need to find the lowest level a role is granted access to a controller stopping if it has explicitly been removed. I plan on listing the roles. When I click a role, I want it to show all the controllers that role has access to. Then clicking on a controller shows the actions the role is allowed to do. So in the example above, a guest is allowed to view the index action of the index controller along with the login action. A member inherits the same access, but is then denied access to the login action and register action. A moderator inherits the rules of a member. So if I were to select the role moderator. I want to see the controller index listed. If I click on the controller, it should show the allowed actions as being action: index. (which was originally granted to the guest, but hasn't since been dissallowed) Is there any examples to doing this. I am obviously working with the Zend MVC (PHP) and MySQL. Even just a persudo code example would be a helpful starting point - this is one of the last parts of the jigsaw I am putting together. P.S. Obviously I have the ACL object - is it going to be easier to interigate that or is it better to do it my self via PHP/MySQL? The aim will be, show what a role can access which will then allow me to add or edit a role, controller and action in a GUI style (that is somewhat the easy bit) - currently I am updating the DB manually as I have been building the site.

• PHP CSV, how to get previous and next 3 rows from current row

  - by Kalpesh Mehta

  I am currently using fgetcsv in php to get rows in CSV file. For each row, I need it's 3 previous rows and 3 next rows for some requirement. while(($data = fgetcsv($handle, 5000, ",")) !== FALSE) { //$data is current row data //I need previous rows and next rows data } I don't know how to try this, as each while iterate will be having the current row's information. Is there anything we can achieve this within the fgetcsv loop? I am also open for other alternatives for this problem.

• Formatting PHP Code within Vim

  - by gacrux

  I'm currently using Vim as a lightweight IDE. I have NERDTree, bufexplorer, supertab, and ctags plugins which do almost everything I want. Only big thing missing for me is auto code formatting. I'm working with some messy PHP code which has inconsistent indenting and code formatting, ideally I could highlight the code I want formatted (whole files would be fine too) and run a command to tidy it. Does anybody have a nice solution for this working in Vim?
