php文件上传总是失败

Jun 23, 2016 pm 02:38 PM

http://www.w3school.com.cn/php/php_file_upload.asp
我看着这个例子做,但是当选中一个文件,点击上传的时候却出现Error 6 ,我在php.ini中的将 upload_tmp_dir 启动设置为 upload_tmp_dir ="C:\WX" 点击上传却显示Invalid file,同样无法上传文件,请指点。

一般的情况,是上传保存的目录不可写造成的。你要好好设置一下

不用修改php.ini 里面的东西,把它还原回去后再试试。

我已经卸载重新安装了,但是依然未能上传文件,不知道到底是哪里的问题,我发现这些开源的软件安装和配置起来都有一定的难度,各种错误也很头疼啊。请问可有解决方法??

$_FILES["file"]
打印一下这个变量看看什么内容再判断
print_r($_FILES["file"]);exit;
Copy after login

Error: 6
表示上传文件不存在

你最好将 upload_tmp_dir 设置到 D: 即以后的驱动器中
因为 C: 驱动器一般都设置为禁止匿名用户的文件操作

$_FILES['file']['error']
其值为 0,没有错误发生,文件上传成功。 

其值为 1,上传的文件超过了 php.ini 中 upload_max_filesize 选项限制的值。 

其值为 2,上传文件的大小超过了 HTML 表单中 MAX_FILE_SIZE 选项指定的值。 

其值为 3,文件只有部分被上传。 

其值为 4,没有文件被上传。 

其值为 6,找不到临时文件夹。PHP 4.3.10 和 PHP 5.0.3 引进。 

其值为 7,文件写入失败。PHP 5.1.0 引进。 

看报错的话,应该是临时文件夹没有写权限或者不存在

版主请帮帮忙 ,我看这个blog的时候,http://blog.csdn.net/k8080880/article/details/6193060,我已经把
IUSR_7195F2AD8ACB471 和 IWAM_7195F2AD8ACB471 都给D:// r// 目录添加到权限,php.ini修改upload_tmp_dir ="D:/r" 为什么上传文件的时候依然显示错误ERROR :6 ,根据“wzb0712”说的,其值为 6,找不到临时文件夹。PHP 4.3.10 和 PHP 5.0.3 引进。 总是无法解决这种问题,请版主帮忙看看。

安装一个wamp试试。

可能跟文件大小有关,报错是临时文件不存在,那就是写入问题了

我试了很多方法依然不凑效啊
代码在这里http://www.w3school.com.cn/php/php_file_upload.asp

为什么会发生这样的情况?请问如何解决?牛人指点指点。

同样是出错,不知道为什么会这样,我相信你的代码和w3school是没问题的,可能是系统问题还是什么其他的原因,我换个系统再试试看。。

不知道你用的是什么环境,建议安装集成环境吧,推荐wampserver ,一般是没有问题的,或者去下载一个别人写好的上传函数,测试一下是否能上传,再找原因吧

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.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
