Objects of php4 Once upon a time, in very early versions, php did not support any object-oriented programming syntax. The Zend engine (ZE1) was introduced in php4, and several new features appeared, including object data The evolution of type.php object types. The first object-oriented programming (OOP) support only implemented the semantics of object associations. In the words of a PHP kernel developer, "php4 objects just bind an array and some methods to together". It is the php object you are going to study now. The second major release of the Zend Engine (ZE2) was in php5, which introduced some new features in php's OOP implementation. For example, properties and methods can be used Access modifiers mark their visibility outside your class definition, overloading of functions can be used to define custom behaviors for internal language constructs, and interfaces can be used to implement API standardization across call chains of multiple classes. As you learn By the time you get to Chapter 11, "PHP5 Objects," you will have built up your knowledge of these features by implementing them in PHP5 class definitions. Practice

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.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
