[RESOLVED] Loop & Code exiting after echoing iframe

[noahssite]

Here is my code:

<?php
if($fileContents == "New Page"){
echo "Please select a layout for this new page.<br />";
if ($handle = opendir('layouts')) {
  	$count = 0;
	while (false !== ($file = readdir($handle))) {
        if ($file != "thumbnails" && $file != "." && $file != "..") {
		   	echo "<iframe src='layouts/$file' style='width:200px;height:200px;' />";
			$count++;
        }
    }
	closedir($handle);
}
echo "<br />Count: $count";
}
?>

The Problem
After the first Iframe is echoed, the PHP exits, just as if I were to use exit();. If I replace echo "<iframe...." with echo $file, it displays three files - which means there should be three Iframes when using the Iframe echo statement. Why is the Iframe exiting my PHP code?
