简单的PHP处理文件上传

一个非常简单的PHP处理文件上传程序。主要是供前端测试使用。主要使用了php自带的两个函数：
is_uploaded_file 和move_uploaded_file。

 -1,
            'message' => 'No files in request, you need declared a named "file" file field!'
        ]);
        return;
    }
    $uf = $_FILES['file'];
    $tmp = $uf['tmp_name'];
    $type = $uf['type'];
    $name = $uf['name'];
    $size = $uf['size'];
    //var_dump($uf);

    $up_dir = './';

    if (is_uploaded_file($tmp)) {
        $dst = $up_dir . basename($name);
        if (move_uploaded_file($tmp, $dst)) {
            echo json_encode([
                'code' => 0,
                'message' => 'success',
                'data' => [
                    'name' => $name,
                    'size' => $size,
                    'type' => $type,
                    'file_path' => 'http://' . $_SERVER['SERVER_ADDR'] . ':' . $_SERVER['SERVER_PORT'] . '/test/' . $name,
                ],
            ]);
            return;
        }
    }
    echo json_encode([
        'code' => -1,
        'message' => 'Upload failed'
    ]);
}

function doGet()
{
    echo
    '

 
  
  
 
 
    
  
    上传文件

    

    
    
 
';
}
