I don't know how to put them in a csv that follows the master as a header and the respondent to be below the master array corresponding the same string and ignore the array content that don't have a pair. Please help I'm desperate.

Answer 1

I used for loop

$data=array();  
          foreach($formHeader as $key=>$value){
            if (array_key_exists($key, $normalized_array)) {
                $data[$key]=$normalized_array[$key];
          }
          else{
            $data[$key]="";

        }   

      }
