Counting files

Anon

I would really like to count the files in one of my directorys (where I keep my pictures) and display the number of files on my homepage.
Like this: "There are 143 pictures on this site"
I understand that its probably very easy, but I´m a real newbie to programming anything else than pure HTML...

Thankful for any help on this!

Got just what you need ;-)

$url1="../../raeetta/avimages/";
$count_jpg = 0;
$directory = opendir($url1);
while( $file = readdir( $directory ) )
{$file_array[] = $file;}
echo"<blockquote><br>";
foreach( $file_array as $file )
{if( $file == ".." || $file == "." )
{continue;}

// edit the jpg to count only files
// with the ext you want

if( !ereg( ".jpg$", $file ) )
{continue;}

$count_jpg++;}
echo"</blockquote>";
closedir($directory);
//
// $count_jpg contains the number
// of jpg files
//

thanks!
but... when I use the script it doesn´t print the number of files...

try putting the script at the top of your page then call the $count_jpg from anywhere...

<font face="arial" size="4">I've got <? echo $count_jpg;?> files for you... </font>

jippie!
Thank you so much!
Guess your not too impressed by my programming skills... ;-)

if you want a smaller and more flexible solution, put this at the end of your file:

<?PHP
function count_files($extension, $directory = "./", $depth = 0) {
static $fileCount = 0;
$handle = opendir($directory);
if (!is_resource($handle)) return(0);
while (false !== ($file = readdir($handle))) {
$fullPath = "$directory/$file";
if ((is_dir($fullPath) || is_link($fullPath)) && ($file != "." && $file != "..")) {
count_files($extension, $fullPath, $depth + 1);
} else if ((strtolower(substr($file, -strlen($extension))) == "$extension")) {
$fileCount++;
}
}
closedir($handle);
return $fileCount;
}
?>

And then just put this where you want your count to show up:
<?PHP echo count_files(".jpg"); ?>

Just put whatever extension you want in place of .jpg to get other counts. This function also checks in subdirectories and can optionally look in any directory. Maybe this will be more useful to you. 🙂

A slightly optimized version:
- you must check wether the dir was opened
- you don't have to load all files into an array
- you don't have to check for . and .. (they won't match the jpg check)
- the regexp should be case-insensitive

$sDirectory="/data2"; 
$iCount = 0; 
if (!$rDirectory = opendir($sDirectory))
{
  echo 'Could not open directory';
}
else
{
  while( $sFile = readdir( $rDirectory&nbsp😉&nbsp😉 
  {
    if (preg_match("/.jpg$/i", $sFile)) 
    {
      $iCount++;
    }
  } 
  echo $iCount; 
  closedir($rDirectory); 
};

A forum, a FAQ, what else do you need?

Admittedly, Vincent's regexp is a better matching solution:

<?PHP
function count_files($extension, $directory = "./", $depth = 0) {
static $fileCount = 0;
$handle = opendir($directory);
if (!is_resource($handle)) return(0);
while (false !== ($file = readdir($handle))) {
$fullPath = "$directory/$file";
if ((is_dir($fullPath) || is_link($fullPath)) && ($file != "." && $file != "..")) {
count_files($extension, $fullPath, $depth + 1);
} else if (preg_match("/\" . $extension / "$/i", $file)) {
$fileCount++;
}
}
closedir($handle);
return $fileCount;
}
?>

<?PHP
function count_files($extension, $directory = "./", $depth = 0) {
static $fileCount = 0;
$handle = opendir($directory);
if (!is_resource($handle)) return(0);
while (false !== ($file = readdir($handle))) {
$fullPath = "$directory/$file";
if ((is_dir($fullPath) || is_link($fullPath)) && ($file != "." && $file != "..")) {
count_files($extension, $fullPath, $depth + 1);
} else if (preg_match("/\" . $extension . "$/i", $file)) {
$fileCount++;
}
}
closedir($handle);
return $fileCount;
}
?>

Sheesh, these computer languages are SO PICKY! Now that I've bumbled a bit, here's a working piece of code. 🙂
