嗨，我正在为我的实习制作一个应用程序，但我收到了一个错误。
请帮我解决这个问题

这是upload.php
<?php
$file_path = "uploads/";
$file_path = $file_path.basename($_FILES['upload_file']['name']);
if(move_uploaded_file($_FILES['upload_file']['tmp_name'], $file_path)){
$result = array("result" => "success");
}else{
$result = array("result" => "failed");
}
echo json_encode($result);
?>
这是我的phpmyadmin输出：/storage/emulated/0/Android/data/com.example.user.appname/files/Pictures/JPEG_20170918_803639971.jpg
我希望我的输出是JPEG_20170918_803639971.jpg
请帮我解决这个问题。
