Include css+php in other page

[auriaks]

I have this table in table1.php

<div class="sidebox">
<div class="boxhead">Prisijunge vartotojai</div>
<div class="boxbody">
<?php 
include('db_conn.php');
$queryget = mysql_query("SELECT * FROM reg_users ORDER BY `date` DESC LIMIT 4") or die("Error with query");
while ($row = mysql_fetch_array($queryget)) 
{ 
    $nick = $row['nick'];    
    $time = $row['time'];
    $date = $row['date'];
    $datet = date("Y-m-d"); 
    $timet = date("H:i:s");
    $id = $row['id'];
    
$time_seconds = 0;
$seconds = explode(':', $time);
$time_seconds += $seconds[0] * (60 * 60);
$time_seconds += $seconds[1] * 60;
$time_seconds += $seconds[2];

$timet_seconds = 0;
$seconds1 = explode(':', $timet);
$timet_seconds += $seconds1[0] * (60 * 60);
$timet_seconds += $seconds1[1] * 60;
$timet_seconds += $seconds1[2];

if ((($time_seconds-$timet_seconds) <= 300) AND ($date == $datet) AND (($time_seconds-$timet_seconds) >= 0)) {
    $var = '1';
    $when = 'Naršo';
    echo "
    <table width='200px';> 
        <tr>
        <td width='100'>
        <font size='0.8' face='Verdana' color='blue'><b>
        <img src='images/online.png' width='13px' height='13px' border='0'><a style='text-decoration:none' href='user.php?id=$id'><font size='0px' face='Verdana' color='green'><b>$nick</a></b></font>
        </b></font>
        </td>
        <td width='40'>
        <font size='0.8' face='Verdana' color='green'><b>$when </b></font>
        </td>
        </tr>
    </table>
    "; 
} else {
    $when = $date;
    echo "
    <table width='204px';>
        <tr>
        <td width='174'>
        <font size='0.8' face='Verdana' color='blue'><b>
        <img src='images/x.png' width='13px' height='13px' border='0'>&nbsp;<a style='text-decoration:none' href='user.php?id=$id'><font size='0px' face='Verdana' color='black'><b>$nick</a></b></font>
        </b></font>
        </td>
        <td width='28'>
        <font size='0.8' face='Verdana' color='black'><b>$when</b></font>
        </td>
        </tr>
    </table>
    ";}} 
?>
</div>
<div class="boxfooter">
</div>
</div>
