How to count files inside a folder using PHP? - php

Question

The following code counts the number of files inside a folder.
<?php
function folderlist(){
$directoryist = array();
$startdir = './';
//get all image files with a .jpg extension.
$ignoredDirectory[] = '.';
$ignoredDirectory[] = '..';
if (is_dir($startdir)){
if ($dh = opendir($startdir)){
while (($folder = readdir($dh)) !== false){
if (!(array_search($folder,$ignoredDirectory) > -1)){
if (filetype($startdir . $folder) == "dir"){
$directorylist[$startdir . $folder]['name'] = $folder;
$directorylist[$startdir . $folder]['path'] = $startdir;
}
}
}
closedir($dh);
}
}
return($directorylist);
}
$folders = folderlist();
$total_files = 0;
foreach ($folders as $folder){
$path = $folder['path'];
$name = $folder['name'];
$count = iterator_count(new DirectoryIterator($path . $name));
$total_files += $count;
echo '<li>';
echo '<a href="' .$path .'index.php?album=' .$name . '" class="style1">';
echo '<strong>' . $name . '</strong>';
echo ' (' . $count . ' files found)';
echo '</a>';
echo '</li>';
}
echo "Total Files:". $total_files;
?>
However for some reason the count is off by 2. I have a folder with 13 files but this code returns count as 15. For an empty folder, this returns a count of 2.
Can someone point to me the issue with the above snippet?

Answer 1

I'm doing it with DirectoryIterator
$files_in_directory = new DirectoryIterator($path_to_folder);
$c = 0;
foreach($files_in_directory as $file)
{
// We want only files
if($file->isDot()) continue;
if($file->isDir()) continue;
$c++;
}
var_dump($c);
For use as function :
function folderlist($directories = array(), $extensions = array())
{
if(empty($directories))
return false;
$result = array();
$total_count = 0;
foreach($directories as $directory)
{
$files_in_directory = new DirectoryIterator($directory);
$c = 0;
foreach($files_in_directory as $file)
{
// We want only files
if($file->isDot()) continue;
if($file->isDir()) continue;
// This is for php < 5.3.6
$file_extension = pathinfo($file->getFilename(), PATHINFO_EXTENSION);
// If you have php >= 5.3.6 you can use following instead
// $file_extension = $fileinfo->getExtension()
if(in_array($file_extension, $extensions)){
$c++;
$result['directories'][$directory]['files'][$c]['name'] = $file->getFilename();
$result['directories'][$directory]['files'][$c]['path'] = $file->getPath();
$result['directories'][$directory]['count'] = $c;
}
}
$total_count += $c;
}
$result['total_count'] = $total_count;
return $result;
}
Displaying results based on GET superglobal:
if(isset($_GET['album']) && !empty($_GET['album']) && !isset($_GET['listfiles']))
{
// We are in directory view mode
$album = $_GET['album'];
// View all directories and their file count for specified album
$view_directory = folderlist(array($album), array('jpeg', 'jpg', 'log'));
// Loop the folders and display them with file count
foreach ($view_directory['directories'] as $folder_name => $folder_files){
$count = $folder_files['count'];
echo '<li>';
echo '<a href="files.php?album=' . $folder_name . '&listfiles=1" class="style1">';
echo '<strong>' . basename($folder_name) . '</strong>';
echo ' (' . $count . ' files found)';
echo '</a>';
echo '</li>';
}
echo "Total Files:". $get_dir_info['total_count'];
}
elseif(isset($_GET['album'], $_GET['listfiles']) && !empty($_GET['album']))
{
// We are in file view mode for folder
$album = $_GET['album'];
// View all files in directory
$view_files = folderlist(array($album), array('jpeg', 'jpg', 'log'));
echo 'Showing folder content of: <b>'.basename($album).'</b>';
foreach($view_files['directories'][$album]['files'] as $file)
{
$path = $file['path'];
$name = $file['name'];
echo '<li>';
echo '<a href="files.php?file=' . $name . '&path=' . $path . '" class="style1">';
echo '<strong>' . $name . '</strong>';
echo '</a>';
echo '</li>';
}
}

Answer 2

This line is still returning the '.' and '..' vars.
if (!(array_search($folder,$ignoredDirectory) > -1))
see: http://php.net/manual/en/language.types.boolean.php
Try
if (!array_search($folder,$ignoredDirectory))
EDIT:
Also change this:
$ignoredDirectory[] = '.';
$ignoredDirectory[] = '..';
to
$ignoredDirectory = array( '.', '..' );
