How to get the number of files in the folder recursive in php

Question

I have folder structure like below in my web application.

How can I get the number of files in each folder recursively using php. I'm working with Codeignaiter. I haven't any idea for how to do this task.

I can't use scandir function because there are no physical directory in path.Only files and folders save in database.

This is my database

Please any help needed. Thank you.

recursive directory iterator or some other recursive function? — Rasclatt, Nov 23 '16 at 05:41

@Tiger - No it's not duplicate I can't use `scandir` function because there is no any path only saving folders and files in database. — Menaka Kariyawasam, Nov 23 '16 at 05:53

Try this function by passing the path as a parameter in it:

function getFileCount($path) {
        $size = 0;
        $ignore = array('.','..','cgi-bin','.DS_Store');
        $files = scandir($path);
        foreach($files as $t) {
            if(in_array($t, $ignore)) continue;
            if (is_dir(rtrim($path, '/') . '/' . $t)) {
                $size += getFileCount(rtrim($path, '/') . '/' . $t);
            } else {
                $size++;
            }   
        }
        return $size;
    }

Thank you for your effort.but I can't use this because its not physical directory.and I can't use `scandir` function because there is no any directory path.only save in database. — Menaka Kariyawasam, Nov 23 '16 at 05:50

If you would like to get, say, all the *.php files in your project folder, recursively, you could use the following: Source

<?php

$Directory = new RecursiveDirectoryIterator('path/to/project/');
$Iterator = new RecursiveIteratorIterator($Directory);
$Regex = new RegexIterator($Iterator, '/^.+\.php$/i', RecursiveRegexIterator::GET_MATCH);

?>

$Regex will contain a single index array for each PHP file.

But the problem is I haven't any `path` only files and folders saving in database and display database data. – Menaka Kariyawasam Nov 23 '16 at 06:09
@MenakaKariyawasam can you show you database entry ? – TIGER Nov 23 '16 at 06:15
I added my database structure.Thanks. – Menaka Kariyawasam Nov 23 '16 at 06:31

You can extend RecursiveArrayIterator to get kind of RecursiveDirectoryIterator but for your virtual filesystem:

class RecursiveVirtualDirectoryIterator extends RecursiveArrayIterator
{
    private $files;

    public function __construct($parentId, $array = [], $flags = 0)
    {
        $this->files = $array;

        parent::__construct(
            $this->getFilesByParentId($parentId),
            $flags
        );
    }

    private $children;
    public function hasChildren()
    {
        $file = $this->current();

        if ($file['is_file']) {
            return false;
        }

        $this->children = $this->getFilesByParentId($file['id']);

        return !empty($this->children);
    }

    private function getFilesByParentId($id)
    {
        return array_filter($this->files, function ($file) use ($id) {
            return $file['parent_id'] === $id;
        });
    }

    public function getChildren()
    {
        $file = $this->current();
        return new static(
            $file['id'],
            $this->children,
            $this->getFlags()
        );
    }
}

Then you can iterate over your array returned from databases using RecursiveIteratorIterator and count files for, say, topmost folders:

$iterator = new RecursiveIteratorIterator(
    new RecursiveVirtualDirectoryIterator(0, $files),
    RecursiveIteratorIterator::SELF_FIRST
);

$currentDirectoryName = null;
$filesCount = [];
foreach ($iterator as $file) {
    if ($iterator->getDepth() === 0 && !$file['is_file']) {
        $currentDirectoryName = $file['name'];
        $filesCount[$currentDirectoryName] = 0;
        continue;
    }

    $filesCount[$currentDirectoryName] += 1; 
}

Here is working demo.

While Standard PHP Library (SPL) is poorly documented, it contains many useful things that save you from reinventing the wheel over and over again.
