counting files with a certain extension

[shadowpawn]

I'm rather new to php.. I'm trying to write a script which will count the number of files with the extension .who in a certain directory. Here is what I've got so far..

$chat_room_dir = '/usr/home/web/users/a0013745/html/RodSerling/Chat/poets';

$chat_dir = dir($chat_room_dir);
$files = array();
while ($entry = $chat_dir->read())
{
if (substr($entry, 0, 3) == 'who')
$files[] = $entry;
}

$usercount = count($files);

echo 'Users currently in chat: ';
echo $usercount;

The problem is, it returns a 0 no matter what. The absolute path is correct. What am I doing wrong? I can't see it..

Further, I was trying to write something to get the info from the .who files.. Inside the file, the first line looks like this
nickname|IP address|<img> and the second line just has the nickname

I had a working perl script which would display the name and the img.. but I need it in php now and can't seem to get the dang thing to work. Anyone willing to give me a nudge in the right direction on this one?

try changing your if check to....

if (substr($entry, strlen($entry)-4), 4) == '.who') 
$files[] = $entry; 

your way is checking for filenames with the pattern of "who*"

I added the . to the check just so it wouldnt grab a file named "who" by itself 😉

although I would write this somewhat like this...

$users=0;
$dir='/usr/home/web/users/a0013745/html/RodSerling/Chat/poets'; 
$d = opendir($dir);
while(($file = readdir($d)) !== false)
{
     if (substr($entry, strlen($entry)-4), 4) == '.who') { $users++; }
}
closedir($d);
echo "Users currently in chat: $users";
