How to check if a PHP POST array has any value set? -


i need check if item in array, part of $_post array, has value. values in empty array set, above example not produce desired results. (this array subset of full $_post array).

(  [columns] =>  [coached_textbox] => 1 [item] => array     (         [first] => array             (                 [coach_menu_value] => 1                 [coach_menu_name] => menu 1             )         [second] => array             (                 [coach_menu_value] =>                  [coach_menu_name] =>              )      (

is there simple way test if either array item has value? test each item in array value, seems inelegant.

this example provided in earlier post gives fine example on how test code initialized array() values.

if ($signup_errors) {   // there error } else {  // there wasn't }

however, doesn't work on array set within $_post array.

use recursive function below traverse array. function return true if array contains at least 1 non-null value or non-empty string.

function traversearray($arr){     $flag = false;     foreach($arr $value){         if(is_array($value)){             $flag = traversearray($value);             if($flag) return true;         }else{             if(isset($value) && $value != '') return true;         }     }     return $flag; }

and how should call function,
(suppose $array original array)

$isnonemptyarray = traversearray($array); if($isnonemptyarray){     // @ least 1 element in array either      // non-null value or non-empty string }else{     // array empty }

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
