file count in directory question

[next]

	$site_root = $_SERVER['DOCUMENT_ROOT'];
$images_dir = $site_root . "/gallery/images";

$dir_handle = opendir($images_dir);
while($file = readdir($dir_handle)) {
	$fileCount++;
	echo "$fileCount - $file<br />";
}

why are the first 2 listed items are dots??? I have 11 files in a directory, count returns 13:

1 - .

2 - ..

3 - 1.jpg

4 - 3.jpg

5 - 2.jpg

6 - 5.jpg

7 - 7.jpg

8 - 8.jpg

9 - 9.jpg

10 - 10.jpg

11 - 11.jpg

12 - 4.jpg

13 - 6.jpg

 

and is there a better way to count files?

 

Thanks.

You can setup a condition in your loop to not count them. 

 

p.s.-

 

no there's not really a "better" way to do it.

i tried

while($file = readdir($dir_handle)) {
if(is_file($file)) {		
$fileCount++;
echo "$fileCount - $file<br />";
}
}

but it returns a null result  ??? .

I pretty much count images, i could use InStr to check, but wondering why is is_file breaking my result.

Any ideas?

The code you provided seems to work just fine for me.  It lists all the files in my directory except the . and ..

 

<?php
   $site_root = $_SERVER['DOCUMENT_ROOT'];
   $images_dir = $site_root; // I took out the path so I could test it on my server

   $dir_handle = opendir($images_dir);
   while($file = readdir($dir_handle)) {
      if(is_file($file)) {	
         $fileCount++;
 echo "$fileCount - $file<br />";
      }
   }
?>

This should work:

 

count(glob("path/to/file/*"));

 

note: If the count is two off, you can use this:

 

count(glob("path/to/file/*")) - 2;

I  would use

while($file = readdir($dir_handle)) 
   {if($file[0] !=".")
       {
	$fileCount++;
	echo "$fileCount - $file<br />";
}
     }

This should work:

 

count(glob("path/to/file/*"));

 

 

I just checked it, and it does. You don't need to use fopen or readdir or anything. Just put the path to the directory you want to check.
