php - DOM和文件获取内容

Question

Which is best for performance usage/usability, "file_get_content" or "DOM LoadHtmlFile" ?

As they both get the html content, what is the optimal situation to use one or the other?

This Also go with the "file_put_content" and "DOM SaveHtmlFile"

Answer 1

I was a newbie back when I posted this question. Here is my conclusion at the time I am writing this,

they both do different things completely. "DOM LoadHtmlFile" is a part of a DOMDocument class which is very powerful to manipulate html formatted content, and file_get_content is used to get file/http content as a string and manipulate as your wish. On a case scenario if the target content are in html format, depending on needs, if requires heavily change then I would personally use DomDocument class. If otherwise, I would just manipulate as a string.
