求教PHP+MYSQL的文件上传下载代码要怎样写?
毕业设计要做一个管理毕业论文的系统,要求学生能将doc格式的毕业论文上传,而导师能将论文下载下来,请问具体的代码要怎样写?
回复讨论(解决方案)
建议网上搜索一下,这种代码网上还是很多的。
上传就是提交表单嘛
处理提交的表单将上传文件处理存在一个路径下,然后将路径存在数据库里,
然后再将论文路径的链接呈现给导师,他一点击就可以下载了
查查PHP的超全局数组$_FILES的用法吧
手册上有现成的例子
网上有现成封装好的文件上传类!
学生页面 student.php
<?phpif($_FILES && $_POST['StudentID']) { if(strtolower(pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION)) == 'doc') { move_uploaded_file($_FILES['file']['tmp_name'], $_POST['StudentID'].'.doc'); echo '上传成功,玩去吧!'; }}?><form method="POST" enctype="multipart/form-data"><input type=text name=StudentID /><br> <input type=file name=file /><br> <input type=submit value=提交></form>
导师页面 tutor.php
<?phpforeach(glob('*.doc') as $fn) { echo "<a href='$fn'>" . substr($fn, 0, -4) . '</a><br />';}
这是基本代码,自己扩充去吧!
将文件用表单提交,数据库存取路径,然后再下载端输出文件路径的列表链接(直接链接到具体文件名称),点击就能下载了
过滤过滤 防止不安全

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.

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,

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.
