PHP complex check between different arrays -

-

my goal decide if $icurrentmembershipid can access $acurrentmenu array based on: if $icurrentmembershipid in $arescrictaccess array. 

if(is_array($arescrictaccess)){    // not sure }

ultimately, need deny access page if users $icurrentmembershipid in $arescrictaccess array.

if(is_array($arestrictaccess)){     if(in_array($icurrentmembershipid, $arestricaccess) === false){         /* display $acurrentmenu */     } }

(assuming mingw) i'm still trying handle on c++ stuff, after reading coun...
