单行注释://,#?
基本语法-》注释

单行注释仅仅注释到行末或者当前的 PHP 代码块,视乎哪个首先出现。这意味着在 // ... ?> 或者 # ... ?> 之后的 HTML 代码将被显示出来:?> 跳出了 PHP 模式并返回了 HTML 模式,// 或 # 并不能影响到这一点。如果启用了 asp_tags 配置选项,其行为和 // %> 或 # %> 相同。不过, 标记在单行注释中不会跳出 PHP 模式。 

“ 标记在单行注释中不会跳出 PHP 模式。”,这句话是什么意思?
给个实例。

可能是译者的表述能力有限吧,原文被翻译的隐晦难懂

其实他表述的是: 
单行注释符“//”、“#” 不能注释掉 php 代码块结束符 ?>
但可以注释掉块结束符 

<script language=php>//</script><br />echo 'aaa';<br />
aaa
<script language=php>//<br /></script><br />echo 'aaa';<br />
echo 'aaa';

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.
