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 */     } }
