while($result=mysql_fetch_array($query)){ ?>

$query_1=mysql_query("select * from table2 where id='$result[id]'");

Make sure to change your database credentials, and table names.  You will have to do the table styling also.

 

<?php
//create the sql query string, take note that the order by clause sorts the countries in alphabetical order
$sql = "SELECT a.country, b.city FROM country AS a JOIN city AS b ON a.country_id = b.country_id ORDER BY a.country";
 
//create a mysqli object
$db = new mysqli("localhost", "my_username", "my_password", "my_database");
//query the database
$result = $db->query($sql);
//create a variable to hold the last known country name.
$last_country = NULL;
//fetch the data, until there are no rows left.
while($row = $result->fetch_assoc()) {
//if the last_country is not equal to the current country, then we start a division (<div>) and a table (<table>)
if($last_country != $row['country']) {
//but if last country does not explicitly equal null, then we first must close the division and the table.
if($last_country !== NULL) {
echo '</table></div>';
}
echo '<div style="float:left;">
<table style="border:1px solid black">
<tr>
<th>' . $row['country'] . '</th>
</tr>';
}
//every run of the while loop should output the city
echo '<tr><td>' . $row['city'] . '</td></tr>';
//after everything is done, we now set the current country, to the last_country (for the new loop).
$last_country = $row['country'];
}

Thank you, jc and i work as your advice above and it works great. but when i trying to work on in my actual database. the header part going into redundant. why?

$x = "SELECT REQUEST.request_id, USER.address FROM pro_user_employee AS USER JOIN pro_request AS REQUEST ON USER.employee_id = REQUEST.employee_id";
$y= mysql_query($x);

You need to order by the indexed column.  This will ensure that all the column names are returned together.

 

 

$x = "SELECT REQUEST.request_id, USER.address FROM pro_user_employee AS USER JOIN pro_request AS REQUEST ON USER.employee_id = REQUEST.employee_id ORDER BY USER.address";

Okay, Thanks JC. but i think when you see my database, you might confuse since it is crowded, i might only me can understand it. but okay i give it to you since i know you are genius and you can understand it well. image below are might different to attachment but u can use it as a sample.

You need to do some data normalization, as well as storing dates in the correct column types.  You were right about the data being confusing, but I think I got you on the right track.  I wasn't sure how or what the last column (balance) was suppose to be calculated by, so I didn't include that.  It would be easy to add, I would like to see what you come up with.

 

Edit: on second look, the last balance is in there, but you image had me adding another one.  Ahh 16hr days...

if(!$result = $db->query($sql)) {
//if query failed, find out why;
echo $db->error;
