How to get random element from multidimensional array in php -

-

i have multidimensional array composed post variables looks this:

$easys = array( array($easy1min,$easy1max,$easy1enc), array($easy2min,$easy2max,$easy2enc), array($easy3min,$easy3max,$easy3enc), array($easy4min,$easy4max,$easy4enc), array($easy5min,$easy5max,$easy5enc), array($easy6min,$easy6max,$easy6enc), array($easy7min,$easy7max,$easy7enc), array($easy8min,$easy8max,$easy8enc), array($easy9min,$easy9max,$easy9enc), array($easy10min,$easy10max,$easy10enc) );

i'm attempting return 1 randomized result this.

my function trying shuffle looks this:

$shuffle($easy_encounters); $num = rand($easy_encounters[0][0],$easy_encounters[0][1]); return "(".$num.") ".$easy_encounters[0][2];

gives

"shuffle expect parameter 1 array.."

i have tried iterator_to_array: 

$easy_encounters = iterator_to_array($easy_encounters);

which returns error

"catchable fatal error: argument 1 passed iterator_to_array() must implement interface traversable..."

then couple attempts using various syntaxes array_rand such as:

$easy_encounters = array_rand($easy_encounters); $num = rand($easy_encounters [0][0],$easy_encounters [0][1]); return "(".$num.") ".$easy_encounters [0][2];

and

$random_obj = $easy_encounters[array_rand($easy_encounters)]; $num = rand($random_obj[0][0],$random_obj[0][1]); return "(".$num.") ".$random_obj[0][2];

i feel i'm hitting around this. admit perhaps not understanding useage of iterator_to_array after got traversable error.

any appreciated. i've trudged around i've gotten examples i've used thusfar.

$randomarray = array_rand($easy_encounters);  echo $easy_encounters[$randomarray][array_rand($easy_encounters[$randomarray])];

first random array. random value array.

$randomarray random array inside of $easy_encounters. bottom line reads echo $easy_encounters[$randomarray][$randomelement inside $randomarray].

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
