关于PHP上传的问题
move_uploaded_file 函数
上传文件
现在的要求是可以上传任意个文件
但是总的文件的大小不能超过5M
该怎么做呢??
------解决方案--------------------
上传文件大小的限制一般在php.ini和httpd.conf配置文件里有修改,比如php.ini里有
upload_max_filesize = 8M
post_max_size = 10M
memory_limit = 20M
这类的设置,在httpd.conf里有
LimitRequestBody 10485760
这类设置
不过你在PHP文件里可以直接判断上传文件大小,比如判断$_FILES["file"]["size"]如果大于5M就不move_uploaded_file 移动。
------解决方案--------------------
上传的同时记录相应的文件上传信息(按照用户,用数据库或文件 记录上传文件的总大小或用户上传每个文件的大小)
之后做相应判断不是可以?
------解决方案--------------------
确认 php.ini 中
session.upload_progress.enabled = on
session.upload_progress.cleanup = off
你可以在
$_SESSION["upload_progress_laruence"]["content_length"]
中得到上传文件的总大小
我想你不会排斥 php 5.4 吧?
------解决方案--------------------
你应该是单个用户的上传总大小吧,在数据库中记录比较好,每个用户加个上传总大小字段,每次对比和更新。
------解决方案--------------------
也就是每次发送邮件的附件不能大于5M,很好判断啊,数据库记录上传总大小,不能大于5M,每次发送文件后清空为0重新计算。
------解决方案--------------------
那也总不至于加法也不会做了吧?

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,

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.
