以上这些常用的举措可以给Apache Server 一个基本的安全运行环境,显然在具体实施上还要做进一步的细化分解,制定出符合实际应用的安全配置方案。 | 以上这些常用的举措可以给Apache Server 一个基本的安全运行环境,显然在具体实施上还要做进一步的细化分解,制定出符合实际应用的安全配置方案。 | ||

要让此方法生效,必须把 PHP 文件的扩展名改为以上的扩展名。这样就通过隐藏来提高了安全性,虽然防御能力很低而且有些缺点。 | 要让此方法生效,必须把 PHP 文件的扩展名改为以上的扩展名。这样就通过隐藏来提高了安全性,虽然防御能力很低而且有些缺点。 | ||

PHP 本身并不能保护数据库的安全。下面的章节只是讲述怎样用 PHP 脚本对数据库进行基本的访问和操作。记住一条简单的原则:深入防御。保护数据库的措施越多,攻击者就越难获得和使用数据库内的信息。正确地设计和应用数据库可以减少被攻击的担忧。 | PHP 本身并不能保护数据库的安全。下面的章节只是讲述怎样用 PHP 脚本对数据库进行基本的访问和操作。记住一条简单的原则:深入防御。保护数据库的措施越多,攻击者就越难获得和使用数据库内的信息。正确地设计和应用数据库可以减少被攻击的担忧。 |

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.

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
