Can't seem to get my JavaScript to get a value from PHP

[Octodonk]

Rightio, I need to count the number of files in a directory then assign that number to a variable in my website. Here is what I have thus far.

PHP Script to count files

$directory = "../comics/";
if (glob($directory . "*.png") != false)
{
 $filecount = count(glob($directory . "*.png"));
 echo $filecount;
}
else
{
 echo 0;
} 

And here is my javascript which is inside my html page

<script type="text/javascript">
var numofImages = "<?=$filecount?>";
var random_img = new Array();
for(var i=0;i<numofImages-1;i++) { 
   random_img[i] = '<a href="comics/'+i+'.png"><img src="comics/'+i+'.png"; width="260" height="320" border="0" alt=""></a>';
}

var random_number = Math.floor((Math.random()*random_img.length));
random_img[random_number];
document.write(random_img[random_number]);
</script>

Now, my problem is this, it wont get the file count. If I set numofImages to an actual number the entire thing works perfectly fine. But for some reason it doesn't seem to get the file count. Any tips?

Cheers.

Not knowing about your personal PHP/Javascript knowledge or how the page(s) are set up I'll first just toss in a little note to make sure that your script code itself is on a .php page and also obviously the same page that sets the $filecount variable.

Silly things out of the way, have you tried:

<script type="text/javascript">
var numofImages = "<?php echo $filecount; ?>";
var random_img = new Array();
for(var i=0;i<numofImages-1;i++) { 
   random_img[i] = '<a href="comics/'+i+'.png"><img src="comics/'+i+'.png"; width="260" height="320" border="0" alt=""></a>';
}

var random_number = Math.floor((Math.random()*random_img.length));
random_img[random_number];
document.write(random_img[random_number]);
</script>

I suppose I could have looked it up quickly, but I have never seen the format <?=$variable?> used to insert PHP in to a page. Generally I always set a proper opening and closing PHP tag and then simply echo out any data I want printed in the page's source.

It is valid if that feature is enabled on the server, but it is indeed generally better to use proper opening and closing php tags and use echo.
