upload multiple

you should add multiple to input element
and change name="img[]";
like it:

<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="img[]" />
    <input type="submit" value="submit">
</form>

and run it , you will get it:

array (size=1)
  'img' => 
    array (size=5)
      'name' => 
        array (size=2)
          0 => string '360截圖20180916201047398.jpg' (length=30)
          1 => string '360截圖20181025200949887.jpg' (length=30)
      'type' => 
        array (size=2)
          0 => string 'image/jpeg' (length=10)
          1 => string 'image/jpeg' (length=10)
      'tmp_name' => 
        array (size=2)
          0 => string 'E:\wamp64\tmp\phpD36A.tmp' (length=25)
          1 => string 'E:\wamp64\tmp\phpD37B.tmp' (length=25)
      'error' => 
        array (size=2)
          0 => int 0
          1 => int 0
      'size' => 
        array (size=2)
          0 => int 40554
          1 => int 30763
