Can php not understand js?
You don’t need to know JS when developing PHP. As a pure back-end developer, you only write background logic and don’t participate in front-end code writing. You don’t need to know JS.
But in most cases, you still need to know js, because PHP programmers in small and medium-sized companies are not only responsible for writing back-end code, but also need to write front-end. And as a website developer, a website made without understanding js will have great limitations and lack many dynamic effects.
JavaScript
JavaScript is a literal scripting language, a dynamically typed, weakly typed, prototype-based language with built-in support for types. Its interpreter is called the JavaScript engine, which is part of the browser and is widely used in client-side scripting languages. It was first used on HTML (an application under Standard Universal Markup Language) web pages to add dynamic functions to HTML web pages. .
