$_GET和$变量有什么区别
比如从另外一个页面接受传入进来的参数 para=1
$_GET['para']和$para都可以用那这2种方式有什么区别？

------解决方案--------------------
$_GET是全局变量，接收以get方式提交的表单，$para只是一个寻常变量。
------解决方案--------------------
质的区别
------解决方案--------------------
$para可以用
只可能是你用的框架会对get进行处理
这样本质上不安全
------解决方案--------------------
看你头像，给你的解释就是自行车和山地车的区别

------解决方案--------------------
$_GET是系统定义的变量 $para只是你自己定义的变量
------解决方案--------------------
从基础开始学吧,不打地基就想盖楼会倒得.
------解决方案--------------------
把php中一个配置改下！你到百度搜下，是为了安全和变量不冲突！
------解决方案--------------------
$_GET是全局变量
你说的$para也能使用
可能是通过extract()函数处理过吧
把键名转变为变量名，键值转变为变量值
------解决方案--------------------
建议楼主看看基础类的书吧，上面都有。这是很基础的东西。这种问题都要拿出来问，只能证明你真的很懒。或者说你的php真的很烂
------解决方案--------------------
现在很少看见这种代码了！

Best Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

Best PHP Performance Optimization TechniquesMay 07, 2025 pm 03:05 PM

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
