using glob to preload images

siege

I would like to learn how to use glob to preload images. What Im trying to do is create a function that reads from a particular directory then loads images into my cache while using CSS to do it. I want to be able to request this file from flash to this. This is what i have so far which is not working exactly:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
<?php
foreach (glob("../test/test_con/*") as $filename) {
   //echo "$filename size " . filesize($filename) . "\n";
   echo "<img src=$filename width=\"$width\" height=\"$height\" alt=\"getimagesize() example\" />";
}

// use * as wildcard before an ext. like "*.jpg" or after a dir. like "/temp/*"
?>
<html xmlns="http://www.w3.org/1999/xhtml">
	<head>
		<meta http-equiv="content-type" content="text/html;charset=utf-8" />
		<title>glob_html</title>
		<style type="text/css">
		<!--
			.preload {
			display: none;
			top: -100px;
			left: -100px;
			*/
			height: 1px;
			width: 1px;
			}
		-->	
		</style>
	</head>
	<body bgcolor="#ffffff">
		<p></p>
	</body>
</html>

Im calling this php code from flash to use as a preloader for my images. When I go to the page (directly) I can see all the images but, when I call it from flash is it really caching them? or does the below need to be in a function to do that?

<?php
foreach (glob("dir/*.jpg") as $filename) {
echo "<img src='$filename'/>";// class='preload'

}
echo "&confirmStatus=worked&";
?>
<html xmlns="http://www.w3.org/1999/xhtml">
	<head>
		<meta http-equiv="content-type" content="text/html;charset=utf-8" />
		<title>glob_html</title>
		<style type="text/css">
		<!--
			.preload {
			display: none;
			/*
			position: absolute;
			top: -100px;
			left: -100px;

		//
		height: 1px;
		width: 1px;
		*/

		}
	-->	
	</style>
</head>
<body bgcolor="#ffffff">
	<p></p>
</body>
</html>

What do you mean that it's "not working exactly?" What is it doing? Can you show us the relevant lines of outputted HTML?
$width and $height are never defined.
You need quotes around the IMG 'src' attributes.
Why is there a '*/' in the middle of your CSS style declaration?
Do you realize that you never actually apply your CSS style to the images?
Is display_errors set to On and error_reporting set to E_ALL ?

I know next to nothing about Flash, but I do know that a bunch of <img> tags on the page prior to the <html> and <body> tags is invalid HTML; so there's no guarantee that the browser does anything at all with those images.

Is this not a duplicate (more or less) of this thread?

NogDog,
Where how would I address it differently?

brad,
yes it appears that my first thread had actually went through before I had a browser failure, im going to the other one to answer your questions, thanx

Im not sure its working for what I want it to do, which is basically call those images before my flash file has a chance to request them from the XML file... this way when its reading the XML file it loads faster b/c the images are already cached.
Heres the php by itself: http://bigrootnyc.com/bigroot_assets/website/bigroot_flash/hscroll_btn_test.html
Then heres a stripped down version of the flash site, press the gear btn then mens to see it work. You will notice I put a var in the php file to let us know it has actually been loaded:
http://bigrootnyc.com/bigroot_assets/website/bigroot_flash/mens_preload.php
I know, Im not exactly sure how to define them, or if they are even needed.
echo "<img src='$filename'/>";
I commented out the part I'm not using is ' / something here / ' not the way to do a multiline. I guess I could always do  i think I dod the above b/c you canin AS, ha.
yes, I just wanted to make sure the tag worked to begin with, rather it called the images and you can see them. Im trying to mix all these different techniques into one, i believe you use the display:none if you plan on using the php page as your page with content, I figured since I wasnt it didnt really matter.
because i lack the knowledge in php I'm not sure what you mean, im guessing its a way to trace whats going on.
