counting files in a directory

[8ride]

I am working on a random image generator for my site and I would like it so that I can simply add files to the directory /coins/ and the script automatically figures out how many files there are and sets the max number in the random script to that. Looking in my beginner's PHP book I can't seem to find anything.

$dir="/coins/";
$a = `find $dir -depth -type f -print`; 
$files = explode ("\n", $a); 

echo (count($files) - 1) . " files in directory";

Ok, that script keeps outputting that I have 0 files in the directory. I took out the "- 1" and it said I had 1 file. After adding 4 files to the directory, same problem. I have checked the path and all.

Try taking out that first slash in front of coins/

I know this code works. I've tested it and currently use it. It may just be that starting slash.

Still no luck. Here is the code I have

<?php
$dir="coins/";
$a = `find $dir -depth -type f -print`;
$files = explode ("\n", $a);

echo (count($files) - 1) . " files in directory";
?>

<?php
srand ((double) microtime() * 10000000);
$RandomNumber = rand (1,2);
echo ("<p>The random number generated was $RandomNumber</p>\n");
echo ("<p><img src=\"../main/coins/coin$RandomNumber.gif\">");
?>

and the result http://www.chumpchange.org/main/coin_gen.php

I'm not quite sure why that doesn't work, but here's another way to get a count:

<?

   if ($handle = opendir('coins/')) {
       $count = "0";

    while (false !== ($file = readdir($handle))) { 

       if ($file != "." && $file != "..") { 
          $count++;

       }

     }

}

closedir($handle); 

echo $count . " files in directory";

?>

Ok thanks, that new script works perfectly.
