The correct way to delete all files older than 2 days in PHP

Question

Just curious

        $files = glob(cacheme_directory().\"*\");
        foreach($files as $file)
        {
            $filemtime=filemtime ($file);
                  


        

Answer 1

Another simplier and more modern way, using FilesystemIterator.

I'm using 'logs' directory as an example.

$fileSystemIterator = new FilesystemIterator('logs');
$now = time();
foreach ($fileSystemIterator as $file) {
    if ($now - $file->getCTime() >= 60 * 60 * 24 * 2) // 2 days 
        unlink('logs/'.$file->getFilename());
}

Main advantage is: DirectoryIterator returns virtual directories "." and ".." in a loop. But FilesystemIterator ignores them.
