Viewing Data From a Table To Modal Using PHP - php

Question

I am using a table to retrieve all the data from the database and an array of view button on each table row. If the view button is clicked, a modal will appear displaying all the information of the particular row.
The problem is that the only id read is the last id. Giving the same view results for each table row.
I have this line of code in the view button:
< button class="btn btn-info" data-toggle="modal" data-target="#myModal-viewaccountinfo">View< / button>
While my modal code is this:
<div class="modal fade" id="myModal-viewaccountinfo" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<h3 class="modal-title"><center>USER ACCOUNT INFORMATION</center></h3>
</div>
<div class="modal-body">
<form method="post" action="">
<br>
<?php
$id = $_GET['txtid'];
include ("connect.php");
$i ="select * from usersvis where userid=".$id;
$h= mysql_query($i);
if($tr=mysql_fetch_array($h))
{
?>
<div class="row">
<div class="col-lg-4">

<div class="col-lg-6">
