I think everything that you need is array key exists   if   array key exists  id    access data  Privilege                        this- gt Session- gt setFlash     Access Denied  You are not eligible to access this      flash custom success                    return  this- gt redirect array  controller    gt   Dashboard    action    gt   index

you can check using php in array   built in function   lt  php    os   array  Mac    NT    Irix    Linux      if  in array  Irix    os         echo  Got Irix       if  in array  mac    os       echo  Got mac       gt    and you can also check using this   lt  php    search array   array  first    gt  1   second    gt  4     if  array key exists  first    search array         echo  The  first  element is in the array             gt    in array   is fine if you re only checking but if you need to check that a value exists and return the associated key  array search is a better option    data   array  0   gt   Key1   1   gt   Key2       key   array search  Key2    data    if   key     echo  Key is      key    else    echo  Key not found       for more details http   php net manual en function in-array php
