count total number of files

[wanaka]

I have a couple of gif files in a directory with the naming pattern of graph.gif graph001.gif graph002.gif graph003.gif

I want to count total number of graph*.gif files found in that directory.

How could I accomplish this

<?php

$count = 0;

/* open the directory so PHP can read it */
$targetDir = "/path/to/dir/";
$dirHandle = opendir($targetDir);

/* loop through the directories files */
while (($file = readdir($dirHandle)) != false)
{
   if (preg_match("/graph.*\\.gif/",$file))
   {
      $count ++;
   }
}

echo($count);

?>
