how to echo banner (both flash & image)

My members that want to advert may upload their banner advert in any of the below format jpg, gif, png & swf. Am having problem echoing out my banners. I can't echo either image or flash with a code, am only able to echo out banners in jpg, gif and png with the below code;

<?php
$getad=mysql_query("SELECT * FROM $table_name ORDER BY RAND() LIMIT 1");
while($rows=mysql_fetch_array($getad)){
$banner=$rows[banner];
}

echo "<img src='../$banner_folder/$banner'>";
?>

PHP:

but it doesn't work for flash banners. am only able to echo flash banner with the below code

<?php
$imglist='';
$img_folder = "images/";
mt_srand((double)microtime()*1000);
$imgs = dir($img_folder);
while ($file  = $imgs->read()) {
if (eregi("swf", $file)) $imglist .= "$file "; }
closedir($imgs->handle);
$imglist = explode(" ", $imglist);
$no = sizeof($imglist)-2;
$random = mt_rand(0, $no);
$image = $imglist[$random];
echo '<embed src="'.$img_folder.$image.'" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="100" height="100"></embed>';
?>

PHP:

But i need a code that can display the banner irrespective of its format. pls help.

 

Are images and flash stored separately? You need different html for each so your php needs to know how to distinguish one from the other. You could try something like:

if (substr($banner,-1,3) == "swf") { 
echo '<embed...'; //fill in the rest
} else {
echo '<img...'; //fill in the rest
}

PHP:

This would check the extension for the banner and echo the appropriate code.
