Show Ads In Middle Of Results - php

Question

I'm currently using sphider on one of my websites, my questions is how can I break the results page into 2 parts to add a 200px break to place a ad slot.
Code:
<?php
extract($search_results);
?>
<?php if ($search_results['did_you_mean']){?>
<div id="did_you_mean">
<?php echo $sph_messages['DidYouMean'];?>: <?php print $search_results['did_you_mean_b']; ?>?
</div>
<?php }?>
<?php if ($search_results['ignore_words']){?>
<div id="common_report">
<?php while ($thisword=each($ignore_words)) {
$ignored .= " ".$thisword[1];
}
$msg = str_replace ('%ignored_words', $ignored, $sph_messages["ignoredWords"]);
echo $msg; ?>
</div>
<?php }?>
<?php if ($search_results['total_results']==0){?>
<div id ="result_report">
<?php
$msg = str_replace ('%query', $ent_query, $sph_messages["noMatch"]);
echo $msg;
?>
</div>
<?php }?>
<?php if ($total_results != 0 && $from <= $to){?>
<div id ="result_report">
<?php
$result = $sph_messages['Results'];
$result = str_replace ('%from', $from, $result);
$result = str_replace ('%to', $to, $result);
$result = str_replace ('%all', $total_results, $result);
$matchword = $sph_messages["matches"];
if ($total_results== 1) {
$matchword= $sph_messages["match"];
} else {
$matchword= $sph_messages["matches"];
}
$result = str_replace ('%matchword', $matchword, $result);
$result = str_replace ('%secs', $time, $result);
echo $result;
?>
</div>
<?php }?>
<?php if (isset($qry_results)) {
?>
<div id="results">
<!-- results listing -->
<?php foreach ($qry_results as $_key => $_row){
$last_domain = $domain_name;
extract($_row);
if ($show_query_scores == 0) {
$weight = '';
} else {
$weight = "[$weight%]";
}
?>
<?php if ($domain_name==$last_domain && $merge_site_results == 1 && $domain == "") {?>
<div class="idented">
<?php }?>
<b><?php print $num?>.</b> <?php print $weight?>
<?php print ($title?$title:$sph_messages['Untitled'])?><br/>
<div class="description"><?php print $fulltxt?></div>
<div class="url"><?php print $url2?> - <?php print $page_size?></div>
<?php if ($domain_name==$last_domain && $merge_site_results == 1 && $domain == "") {?>
[ More results from <?php print $domain_name?> ]
</div class="idented">
<?php }?>
<br/>
<?php }?>
</div>
<?php }?>
<!-- links to other result pages-->
<?php if (isset($other_pages)) {
if ($adv==1) {
$adv_qry = "&adv=1";
}
if ($type != "") {
$type_qry = "&type=$type";
}
?>
<div id="other_pages">
<?php print $sph_messages["Result page"]?>:
<?php if ($start >1){?>
<?php print $sph_messages['Previous']?>
<?php }?>
<?php foreach ($other_pages as $page_num) {
if ($page_num !=$start){?>
<?php print $page_num?>
<?php } else {?>
<b><?php print $page_num?></b>
<?php }?>
<?php }?>
<?php if ($next <= $pages){?>
<?php print $sph_messages['Next']?>
<?php }?>
</div>
<?php }?>
<div class="divline">
</div>
I'm also not aware of a live PHP code editor, if you know of one please comment and share so I can add a link!

Presuming $from and $to are the result numbers, so you're displaying "Showing results 10 to 30 of 100" for example:
<div id="results">
<!-- results listing -->
<?php $adbreak = ($to - $from) / 2;
<?php foreach ($qry_results as $_key => $_row){
<?php if ($adbreak == 0) { ?>
<div id="results-adbreak">
<img src="buy-a-car.jpg" alt="one careful owner!" />
</div>
<?php }
$adbreak--;
?>
// rest of your code
This will put a div approximately (give or take one) half way down your page of results. You can obviously replace the ad with a call to whatever you want.
adding something like:
<?php $adbreak = ($to - $from) / 2;
<?php if ($adbreak < 5) $adbreak = -1; ?>
will ensure that it doesn't display at all if the results list is too short.
If you don't know $to and $from in advance, you can still do it, but you'll have to calculate the equivalent from the query result first.
