我有一个变量声明并在一个php文件中给出一个值，我怎么能将该变量与存储在另一个php文件中的值一起使用？

Question

the website is like a social media.

The first php file does the log in, and it will have a variable $name1 where the username of the logged on user will be stored

I need to that same variable with the username value stored in it in another php file where I create a query containing all the posts from that user.

How can I use that variable in my second php file?

Uses Sessions

in login.php

session_start();
$_SESSION['user'] = $name1;

on nextPage.php

session_start();
$username = $_SESSION['user'];
