linux环境 上传文件失败 tmp_name为空

Jun 23, 2016 pm 02:17 PM

Linux 上传 权限

phpinfo显示的信息如下
file_uploads On
upload_max_filesize 2M
upload_tmp_dir /Users/ririn/Sites/tmp
然后 我对 这个目录设置了777权限 chmod 777 /Users/ririn/Sites/tmp   是不是还有什么需要设置的地方?
但是上传文件 还是不行啊 
首先tmp目录中就没有任何文件
当然后台用$tmp=$_FILES['mypic']['tmp_name']; 这个也无法得到...

在win中是可以正常运行的  win中的配置和这里的一样 我选的文件也只有100多k  

还是贴一下我的代码 是不是linux的要加上一点什么

                File1: 

                upimg

                
                
            



$tmp=$_FILES['mypic']['tmp_name'];    //空的  
$name=$_FILES['mypic']['name'];
$size=$_FILES['mypic']['size'];
$arr =array(
    'tmp'=>$tmp,
    'name'=>$name,
    'size'=>$size
    );
var_dump($arr);

?>
最后打印的是  array(3) { ["tmp"]=> string(0) "" ["name"]=> string(9) "scoot.png" ["size"]=> int(0) } 这样的
win中完全正常

可以在form指向的php页面直接print_r($_FILE)试试有无结果.

var_dump($_FILES);

啊  结果是这样的  
array(1) { ["mypic"]=> array(5) { ["name"]=> string(9) "scoot.png" ["type"]=> string(0) "" ["tmp_name"]=> string(0) "" ["error"]=> int(2) ["size"]=> int(0) } }
还就是什么都没有啊  只有文件名  

var_dump($_FILES);
结果是这样的  
array(1) { ["mypic"]=> array(5) { ["name"]=> string(9) "scoot.png" ["type"]=> string(0) "" ["tmp_name"]=> string(0) "" ["error"]=> int(2) ["size"]=> int(0) } }
还就是什么都没有啊  只有文件名  

结果中有  ["error"]=> int(2)
手册上说
UPLOAD_ERR_FORM_SIZE
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。

我就不说了

嗯  我换了一个文件 好了 但是我原来的那个文件才278K  但是我设置的upload_max_filesize是2M

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,

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

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.

What is REST API design principles? What is REST API design principles? Apr 04, 2025 am 12:01 AM

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

How do you handle exceptions effectively in PHP (try, catch, finally, throw)? How do you handle exceptions effectively in PHP (try, catch, finally, throw)? Apr 05, 2025 am 12:03 AM

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

What are anonymous classes in PHP and when might you use them? What are anonymous classes in PHP and when might you use them? Apr 04, 2025 am 12:02 AM

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
