在 Code Igniter 下拉数组中获取 while 循环

我正在尝试向下拉列表中添加一组虚拟选项，以使一些 jQuery 代码能够工作。问题是，虽然循环正在工作，但我不知道如何将下拉菜单设置为循环并获取所有 50 个虚拟值，但它只返回第一个值。我知道这就像 PHP 初学者的东西，但循环和数组似乎总是让我感到困惑。

$dummy_value = array('UNASSIGNED');
while ($i <= 50)
{
    $dummy_value = "''=> 'null'";
    $i++;
}

echo form_dropdown('employee_manager',array('null'  => 'Please Select A Manager', $dummy_value)); ?>

理想情况下，我希望 form_dropdown 包含 50 个 ''=>;空值。理论上，我们可以将整个数组（包括第一个选项）添加到循环或变量中（我认为）

I'm trying to add a set of dummy options to my dropdown to make some jQuery code work. The problem is that although the loop is working I can't figure out how to set the drop down to loop though and get all 50 dummy values it just returns the first one. I know this is like beginner PHP stuff but loops and arrays seem to always be confusing to me.

$dummy_value = array('UNASSIGNED');
while ($i <= 50)
{
    $dummy_value = "''=> 'null'";
    $i++;
}

echo form_dropdown('employee_manager',array('null'  => 'Please Select A Manager', $dummy_value)); ?>

Ideally I want the form_dropdown to contain 50 of ''=> null vaules. In theory we could add the whole array including the first option to the loop or a variable (I think)
