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 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.
