How can I get this to display in 1 loop - php

Question

In the backend of my website, I have added more categories as follows
<strong>Tour category : </strong><br />
<select name="category_id">
<?php
foreach($category_lists as $list){
if($list['id'] == $arr_collect['category_id']){
$sel = ' selected="selected" ';
}else{
$sel = null;
}
echo '<option value="'.$list['id'].'"'.$sel.'>'.$list['name'].'</option>';
}
?>
</select>
<br clear="all" />
<strong>Tour category 2: </strong><br />
<select name="category_id2">
<option value="">Select Another</option>
<?php
foreach($category_lists as $list){
if($list['id'] == $arr_collect['category_id2']){
$sel = ' selected="selected" ';
}else{
$sel = null;
}
echo '<option value="'.$list['id'].'"'.$sel.'>'.$list['name'].'</option>';
}
?>
</select>
<br clear="all" />
<strong>Tour category 3: </strong><br />
<select name="category_id3">
<option value="">Select Another</option>
<?php
foreach($category_lists as $list){
if($list['id'] == $arr_collect['category_id3']){
$sel = ' selected="selected" ';
}else{
$sel = null;
}
echo '<option value="'.$list['id'].'"'.$sel.'>'.$list['name'].'</option>';
}
?>
</select>
In the front end, I have this
<?php
$sql_ci = "SELECT * FROM location WHERE parent_id <> 0 ORDER BY parent_id, sort ";
$result_ci = mysql_query($sql_ci);
$cities = $Manager->fetchAssoc($result_ci); //peek_array($cities);
if(!empty($cities)){
foreach($cities as $city){
$i = 1; // for active category
$sql_count = "SELECT * FROM tour t, tour_category c
where t.location_id = {$city['id']} and t.type = 'P'
group by t.category_id AND t.category_id2"; //echo $sql_count.'<br />';
$result_count = mysql_query($sql_count);
$count = $Manager->fetchAssoc($result_count);
?>
<ul class="tours-accord tour-private" id="tourcity<?php echo $city['id'];?>">
<?php
$sql_ca = "SELECT * FROM tour_category ORDER BY sort";
$result_ca = mysql_query($sql_ca);
$categories = $Manager->fetchAssoc($result_ca);
if(!empty($categories)){
foreach($categories as $cat){
$sql_tour = "SELECT t.* FROM tour t
WHERE
t.touronline = 'yes'
AND t.category_id = {$cat['id']}
AND t.location_id = {$city['id']}
and t.type = 'P'
ORDER BY t.tourcode";
$result_tour = mysql_query($sql_tour);
$tours = $Manager->fetchAssoc($result_tour);
if(!empty($tours)){
?>
<li style="border-bottom:1px solid gray;">
<?php echo $city['name']; ?> - <?php echo $cat['name']; //echo ' '.$i.' ';?>
<ul>
<?php foreach($tours as $tour){
if(!empty($tour['intro_image'])){
$img = $tour['intro_image'];
}else{
$img = 'default.jpg';
}
?>
<a href="tour-details.php?code=<?php echo $tour['tourcode'];?>" class="tourname">
<li class="<?php if($i == count($count)){echo 'active';} ?>">
<img src="uploaded-items/tour-introimage/<?php echo $img; ?>" width="150" height="100" />
<span class="tourname"><?php echo $tour['tourname'].'(Code: '.$tour['tourcode'].')'; ?></span>
<p><?php echo $tour['intro']; ?></p>
<div class="home-tour-info">
<img src="images/btn-more-info-green-dark.jpg" alt="More info" class="moreinfo"/>
<div class="home-tour-price"><?php echo $tour['promotion_label']; ?></div>
</div>
</li></a>
<?php } ?>
</ul>
</li>
<?php $i++;}}} //each category ?>
The way I made it work was post the last bit 3 times and changed category_id to category_id2, category_id3. But this displayed duplicate categories.
How can I make all this just in 1 loop instead of 3?

Your backend loop is like wise as follows, as a optimising code,
<?
$numcount = 3;
for($i=0;$i<$numcount;$i++) { ?>
<strong>Tour category <?=$i+1?>: </strong><br />
<select name="category_id<?=$i+1?>">
<?php
foreach($category_lists as $list){
if($list['id'] == $arr_collect['category_id'.($i+1)]){
$sel = ' selected="selected" ';
}else{
$sel = null;
}
echo '<option value="'.$list['id'].'"'.$sel.'>'.$list['name'].'</option>';
}
?>
</select>
<br clear="all" />
<? } ?>
