It is not ouputting values in array when echoed

Question

I think there is a problem when I echo $whereArray and orderByArray. If I type in a word such as "Question" and then submit it, I expect it to display in the echos "%".Question."%"; for both arrays. But instead in both echos it just displays "Array" for both echos. Does this mean that both arrays are not working when it comes to storing in the values?

 $searchquestion = $_GET['questioncontent'];
    $terms = explode(" ", $searchquestion);

$whereArray = array();
$orderByArray = array();


    //loop through each term
    foreach ($terms as $each) {
        $i++;
        $whereArray[] = "%".$each."%";
        $orderByArray[] = "%".$each."%"; 


    }

        echo $whereArray;
        echo $orderByArray;

echo() only works for strings. PHP converts your array to "Array" as a fallback.

When you're debugging, you should use var_dump(). It will tell you the type of the object and its content.
