Answer 1

Use the below code for your reference..

$filename = basename($_FILES["file"]["name"]);
$target_dir = "../../file/";
$target_file = $target_dir . basename($_FILES["file"]["name"]);

if(isset($_POST["submit"])) {       
        move_uploaded_file($_FILES["file"]["tmp_name"], $target_file);
        echo "</br>The file ". basename( $_FILES["file"]["name"]). " has been uploaded.";
        }

Answer 2

您的allowedExts与小写不匹配，尝试这个小修改。

$extension = strtoupper(pathinfo( $_FILES["file"]["name"], PATHINFO_EXTENSION));
