You might be able to do something like this - invoke a custom function for each element in the array to see if it passes your criteria

$values=array_filter($_POST,function( $item ){
    return !is_null( $item ) && !empty( $item ) && strlen( trim( $item ) ) > 0 && $item!='';
});

  $newArr = [];
  foreach($myArr as $key => $val){
      if(!empty($val)){
          $newArr[$key] = $val;
      }

  }

Thank you for this code snippet, which may provide some immediate help. A proper explanation [would greatly improve](//meta.stackexchange.com/q/114762) its educational value by showing *why* this is a good solution to the problem, and would make it more useful to future readers with similar, but not identical, questions. Please [edit] your answer to add explanation, and give an indication of what limitations and assumptions apply. – Toby Speight Jul 19 '17 at 12:00
