下图中里面的对象调用方法时不是写index( )这一方法,而是写成了-->$a() 这是为啥呢
回复讨论(解决方案)
$_GET['a']是超链接上的一个参数名,$a=不是$_GET,你把$a打出来看就知道了
我的问题是:
为啥这里不这样写$controller->index()呢
而是写成了$contrlooer->$a()
剑尊】狠狠幸福
这么写完全没问题啊

$controller->index() 这么写不就写死了吗。

要是这么写,那url中 a 只能等于index 只能调 index 这一个方法。。

一个controller 肯定不只 index 这一个方法啊
说白了这里是引用传值

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.

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.
