目标目录不存在
请不要自行处理错误
贴出 print_r($_FILES["file"]); 的结果

感谢您的回复,这个问题已经解决了,现在可以上传图片,但又有一个新问题,就是我想保存的时候把图片的名字给改了方便使用,请教,应该再上面的代码上加哪些语句???本人菜鸟,希望大家多多指教!谢谢啦!!!

$type=strrchr($_FILES["file"]["name"],"."); //获取扩展名
  move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . time().$type); //以当前时间戳命名

$type=strrchr($_FILES["file"]["name"],"."); //获取扩展名
  move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . time().$type); //以当前时间戳命名

$type=strrchr($_FILES["file"]["name"],"."); //获取扩展名
  move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . time().$type); //以当前时间戳命名 以时间戳明名是不错,但是有其他的好的方法吗

我想问,用3楼的方法还能找到我的图片吗?

当然能,跟原来一样,还是在upload文件夹里面。

我刚才试着改了一下,可是图片的名字没有变,只是数据库里存的名字变了… 是不是我弄错了?

我想问,用3楼的方法还能找到我的图片吗?

在文件名的前面加上了时间, 可以看看time()函数.

图片还是那个图片,名字也还是以前的名字,只是数据库里存储的名字变了,那么数据库表里的信息怎么能和图片对应上呢???不解中……

move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . time().$type); //以当前时间戳命名

当你用这一行代码的时候,文件名加上时间戳.好好检查一遍吧.

太感谢了!!!我的问题解决了!!!

如果出现错误,一步一步的来排查

哥们儿 请问你这个问题怎么解决的?我遇到了和你一样的问题?

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
