W3School教程中的文件上传,我复制这两个文件,一在浏览器下上传文件,就只返回 invalid file



------解决方案--------------------
print_r($_FILES['file']) 看看你上传的文件信息,就知道问题在哪儿了
------解决方案--------------------
经测试,没有问题~

可能你上传的图片大小超过了20K.. 你的条件中有大小限制:

PHP code
&& ($_FILES["file"]["size"] 
                 
              
              
        
            
Copy after login
