如何将分隔的单词分隔成一个数组，其中键是分隔符的左边部分，并且右边的部分值

Question

I have a string like this, where each word is marked with encoding (FW, PRP, etc) using underline:

Hi_FW !_.
My_PRP$ name_NN 's_POS Jim_NNP ._.
I_PRP 'm_VBP from_IN New_NNP Zealand_NNP ._.
This_DT is_VBZ my_PRP$ friend_NN ._.
His_PRP$ name_NN 's_POS Adam_NNP ._.
He_PRP 's_VBZ from_IN Australia_NNP ._.
This_DT is_VBZ my_PRP$ friend_NN too_RB ._.
Her_PRP$ name_NN 's_POS Paola_NNP ._.
She_PRP 's_VBZ from_IN Italy_NNP ._.

I need to break it into an array where a key is a word, and its value is its corresponding tag:

[
    "Hi" => "FW",
    "My" => "PRP$",
    "name" => "NN"
    ...
]

I assume I can somehow split this string by the delimiter _, but can't seem to find a good way to then join it into the array I need.

How can that be achieved?

$arr = explode("
", $string);
$newarr = array();
foreach($arr as $item)
{
    $explodeditem = explode(' ', $item);
    foreach($explodeditem as $string)
        array_push ($newarr, $string);
}
$result = array();
foreach($newarr as $item)
{
    $newArr = explode('_', $item);
    $result[$newArr[0]] = $newArr[1];
}
