[PHP] Problems with arrays

[Phpu]

Hi,

I have this array:

$array = array(element1, element2, element3, element4)

I want to list all elements of this array, so i used:

  foreach ($array as $index => $element) {
        $InputString = "$element";
         echo "$InputString";
           }

but this code lists the elements like this: element1 element2 element3 element4

How can i list my elements like this: 
element1
element2
element3
element4


Thanks
