Answer 1

Use a foreach loop:
<?php session_start(); include("sidebar.php"); include "config.php"; $sel="select * from new_project"; $rs=mysql_query($sel); ?>
<div class="h_right">
<h1> +ADD New Project </h1>
</div>
<div class="h_left">
<table border="2px" cellpadding="10px">
<tr>
<td>Id</td>
<td>Project Name</td>
</tr>
<?php foreach($rec=mysql_fetch_assoc($rs) as $project) { ?>
<tr>
<td><?php echo $rec['id'] ?></td>
<td><?php echo $project['project_name'] ?></td>
<?php } ?>
</table>
</div>
new_project.php doesn't need a project id
projectdetail.php will display project based on the project id passed
