How to fetch arrays with string in php

Question

how can i fetch data in an arrays with gives null value if null

here is my data I var_dump($showStatus); I want to print out . $showStatus[0]['title']

string(0) ""
    array(2) {
      [0]=>
      array(7) {
        ["id"]=>
        string(1) "1"
        ["container_id"]=>
        string(1) "3"
        ["title"]=>
        string(51) "waitting"
      }
      [1]=>
      array(7) {
        ["id"]=>
        string(1) "2"
        ["container_id"]=>
        string(1) "3"
        ["title"]=>
        string(72) "getting"
      }
    }
    array(1) {
      [0]=>
      array(7) {
        ["id"]=>
        string(1) "4"
        ["container_id"]=>
        string(1) "7"
        ["title"]=>
        string(51) "getting"
      }
    }

The reason that I've string because in my models I want to print "" or NULL when it don't have data here is my models

public function showStatus($id){
    $sql = 'SELECT * FROM status WHERE container_id = '.$id;
    if($this->query_rows( $sql )) {
        return $this->query_rows($sql);
    } else {
        return "";
    }
 }

I try to use

foreach ($getListData as $k) {

}

but it said Warning: Invalid argument supplied for foreach()

can you just print_r($showStatus); and check the array .

Try this:

if(!empty($getListData) )
{
    foreach ($getListData as $k) {
       print_r($k);
    }    
}
else {
    echo "NULL";
}
