Simple Ad Rotator
This is a simple function that can be used to create ads that rotate according to a random order. Easy to setup and customize. Just define your ads and set the number of ads displayed at once on your page. No database is required.
See a live example!
Haw to use?
To define a new ad just insert a new line like this:
$ad[] = array(“Ad title “, “Ad description “, “Display URL”, “URL”);
To display the ads include the file “ad_rotator.php” and after that call the functions show_ads().
Example:
<?php
include (”/path/to/ad_rotator.php“);
show_ads(3); // this will display 3 ads
show_ads(1); // this will display 1 ad
?>

Can you please tell me how i can display and rotate several 125×125 graphics on a page. Also can you show me how to format how they will appear on the page? The graphics that I need to rotate are here… http://www.phatfiber.com/thismonth1.htm
Thanks in advance for any help. I don’t know much about how to use PHP script. Thank you.

I like this … I’m looking at it, wondering how I can replace the ‘text’ with Images - so I can display Banner ads, and/or Text ads - This would allow me to cut out middle men and advertisers can pay ME for spots on my site, or websites; It’s late; im going to bed; Im going to contact you about this soon; any ideas on Displaying the Banners would be great

Yes, you can use images. When I was the webmaster for gotostcroix.com and during the redesign we needed to rotate the paid advertisers on the appropriate pages, e.g., resorts.
I also used more fields //USAGE $ad[] = array(”Images”, “Ad Title and contact info”, “display url”, “URL”,”ad copy”);
I modified the above to script to:
// create ads
$show_ads = “”;
for($i=0; $i<$number_of_ads; $i++){
$e = $ad[$rand_keys[$i]];
$show_ads .= ”
{$e[0]}
{$e[1]}
{$e[2]}
{$e[4]}
“;
}
$show_ads .= “”;
echo $show_ads;
}
?>
Example of code:
$ad[] = array(”", “Main Title
Subtitle
Phone”, “domainname.com”, “http://www.domainname.com/”, “Text for ad goes here.”);
You can see it in action here: http://www.gotostcroix.com/resorts.php

Okay, not all of the code came through:
// creade ads
$show_ads = “<table width=’100%’ border=’0′ cellspacing=’0′ cellpadding=’5′ class=’ads’>”;
for($i=0; $i<$number_of_ads; $i++){
$e = $ad[$rand_keys[$i]];
$show_ads .= ”
<tr><td colspan=’2′ width=’100%’><br /><hr /><br /></td></tr>
<tr><td width=’200′><div align=’center’>{$e[0]}</div></td>
<td><p>
{$e[1]}
<a href=’{$e[3]}’ style=’font:10pt Arial; color: #009900′ target=’_blank’>{$e[2]}</a></p>
<p style=’text-align:justify;’>{$e[4]}</p>
</td></tr>
“;
}
$show_ads .= “</table>”;
echo $show_ads;
}
?>
