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

                

                <?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.

Usage example:

                To see all the files, and count the space usage:

                

                <?php

                $ite=new RecursiveDirectoryIterator("/path/");

                
 $bytestotal=0;
 $nbfiles=0;

                foreach (new RecursiveIteratorIterator($ite) as $filename=>$cur) {

                    $filesize=$cur->getSize();

                    $bytestotal+=$filesize;

                    $nbfiles++;

                    echo "$filename => $filesize\n";

                }

                
 $bytestotal=number_format($bytestotal);

                echo "Total: $nbfiles files, $bytestotal bytes\n";
 ?>

If you don't get a fully recursive listing, remember to check your permissions on the folders. I just spent 2 hours to find out my root folder didn't have +x on it. I did a chmod g+x and now get a full listing. Oddly, I was able to get a listing of files/folders one level UNDER that folder, but nothing beyond that point which was cause for the confusion.

Usage example:

                

                <?php

                

                $path = realpath('/etc');

                
 $objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);

                foreach($objects as $name => $object){

                    echo "$name\n";

                }

                
 ?>


                This prints a list of all files and directories under $path (including $path ifself). If you want to omit directories, remove the RecursiveIteratorIterator::SELF_FIRST part.
