1. Why Learn Object-Oriented Programming in PHP

Object-oriented programming is an advanced topic in programming; it can be relatively difficult to understand, but it does not require a lot of syntax knowledge.

Common PHP frameworks such as Laravel, ThinkPHP, etc., are all based on object‑oriented principles.

Although the initial setup for OOP can be cumbersome, its later application is highly convenient; custom‑written classes can be flexibly used across various projects.

Mastering OOP is considered stepping into the fascinating world of programming, giving us new perspectives on many problems.
