如何在php中显示用户信息？

Question

I am trying to figure out how to display user information after they've logged in. I am not sure whether I should create a single php file which would display user information depending on the session or should I create different files for different users. I am also having trouble grabbing the header.

here's my code for login.php

<?php
session_start();

require 'dbh.php';


$username = $_POST['uname'];

$password = $_POST['pwd'];


$sql = "SELECT * FROM  registeredusers WHERE UserName = '$username'";

$result = mysqli_query($connection,$sql);

$row = mysqli_fetch_assoc($result);


$hashed_Password = $row['Password'];

$Dehash = password_verify($password,$hashed_Password);



if($Dehash == 0){

echo "username or password is incorrect";

exit();


} else{




$sql = "SELECT * FROM  registeredusers WHERE  UserName='$username' AND Password='$hashed_Password'";

$result = mysqli_query($connection,$sql);



if (!$row=mysqli_fetch_assoc($result)){


echo "Your User Name or Password is incorrect";

}

else {

$userid = $row['id'];

$_SESSION['UserName'] = $row['UserName'];


header("Location: userhomepage.php?user_id=".$userid);

}


}

?>

The following code redirects to userhomepage.php and the user ID is in the url can someone also tell me how do I grab the user ID from the url? I only started coding in PHP a week ago I am fairly new so if guys have any pointers for me that would be great.

You should create a single page that displays user information based on session... you don't want to have to hand-make a new page every time a user signs up!

how do I grab the user ID from the url

echo $_GET["user_id"];
