manual php array only returning last value

Question

I am populating a wordpress gravity form using one of there pre render filters.

I follow their documentation normally and I dynamically populate $items[] using a foreach loop which works every time.

But this time I am not dynamically making a php foreach loop for the $items[] array, I am manually inputting each value into an array.

Please see below...

add_filter("gform_pre_render", "populate_dropdown_bike_make");
add_filter("gform_admin_pre_render", "populate_dropdown_bike_make");
function populate_dropdown_bike_make($form){
    if($form["id"] != 4)
        return $form;

    $items = array();
    $items[] = array(
        "text" => "", "value" => null,
        "text" => "YAMASAKI", "value" => "YAMASAKI",
        "text" => "YAMOTO", "value" => "YAMOTO",
        "text" => "YEZDI", "value" => "YEZDI",
        "text" => "YIBEN", "value" => "YIBEN",
        "text" => "YIYING", "value" => "YIYING",
        "text" => "YONGKANG", "value" => "YONGKANG",
        "text" => "YONGWANG", "value" => "YONGWANG",
        "text" => "ZEBRETTA", "value" => "ZEBRETTA",
        "text" => "ZENNCO", "value" => "ZENNCO",
        "text" => "ZEPII", "value" => "ZEPII",
        "text" => "ZERO-MOTORCYCLES", "value" => "ZERO-MOTORCYCLES",
        "text" => "ZEV", "value" => "ZEV",
        "text" => "ZHEJIANG", "value" => "ZHEJIANG",
        "text" => "ZHENHUA", "value" => "ZHENHUA",
        "text" => "ZHIXI", "value" => "ZHIXI",
        "text" => "ZHONGYU", "value" => "ZHONGYU",
        "text" => "ZING", "value" => "ZING",
        "text" => "ZIPPI", "value" => "ZIPPI",
        "text" => "ZIPSTAR", "value" => "ZIPSTAR",
        "text" => "ZONGSHEN", "value" => "ZONGSHEN",
        "text" => "ZONTES", "value" => "ZONTES",
        "text" => "ZUNDAPP", "value" => "ZUNDAPP"   
    );

    foreach($form["fields"] as &$field)
        if($field["id"] == 45){           
            $field["choices"] = $items;
        }

    return $form;

}

Now the problem with this is it is only returning the very last option ZUNDAPP in the dropdown.

Can anyone see why this is happening?

Thanks

You're redefining the same keys over and over.

$items[] = array(
    "text" => "", "value" => null,
    "text" => "YAMASAKI", "value" => "YAMASAKI"
)

Gives:

array(array(
    "text" => "YAMASAKI",
    "value" => "YAMASAKI"
));

In think you intend:

//    v-- no [] here
$items = array(
    array("text" => "", "value" => null),
    array("text" => "YAMASAKI", "value" => "YAMASAKI"),
    // etc.
