php表单提交大量数据、上千个文本框时发生数据丢失、数据不完整等问题的解决方法,需要的朋友可以参考下
最近在项目中,出现一个奇怪的现象,有一个大form里面有上千个input,提交的时候,老是发现post过来的数据不完整,一开始还怀疑是html 表单名称有冲突,排除掉了。
然后,网上找了一堆,php.ini 的post_max_size和upload_max_filesize都设置了很大的值,没用,nginx的client_max_body_size 500m;加到了那么大的值,也没用。最后终于google到办法:原来PHP从5.3.9开始增加一个变量 max_input_vars 用来限制提交的表单数量。
该值默认情况下是1000 , 不能满足有1000个以上输入项的需求,所以得在php.ini 里面加上更大的值如:
修改后重启apache,终于一切正常!

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
