Searching the internet there seems to be many ways of traversing directories and files
Can some one suggest what the best way to this?
Within the "root" directory there should only be sub directories the name of each is required and processed separately
within each sub directory should only be files each one needs processing according to file extension
This is a windows system so how do I deal with'.' and '..'?
This is how far I've got and isn't tested more to give you an idea of what I'm trying to do
<?PHPerror_reporting(E_ALL);$DS = DIRECTORY_SEPARATOR;$root ="path" . $DS . "to" . $DS . "root";$Dirs= scandir($root);foreach($Dirs as $dir){//$dir name is wanted $dh = opendir($dir);while (false !== ($fileName = readdir($dh))) { $ext = substr($fileName, strrpos($fileName, '.') + 1); if($ext == "html"){ $htmlFile = $dir . $DS . $fileName; // Open and Do stuff with html file } elseif(in_array($ext, array("jpg","jpeg","png"))){ //Do other stuff } else{ // Error code file type not needed } }}
@gr8gonzo - I did the same thing a couple months back but nice to see the results confirmed.

Yep, never had run the test myself before. :)

I expect you will find it to be even faster on PHP7, however to get a consistent test, you'll need to use the same I/O subsystem. I didn't bother to time it because the response was essentially instantaneous on my server where there are less than 100,000 files.
Using "$ext = substr($fullPath, strrpos($fullPath, '.') + 1);" only works if the file has an extension
Path.To/ReadMe fails
Path.To/ReadMe.txt works

a list of full path files I assume there are methods for breaking it into components
Yes, but this seems to be a different question.
"$ext = substr($fullPath, strrpos($fullPath, '.') + 1);" only works if the file has an extension
Yes, that makes sense. You might want to choose the second example I posted above, using the function dirToList(). It gives full file paths all the way to the file, and does not give paths to directories. You may want to sort the list. And if your files do not have extensions, that is a separate issue and worthy of another question. We will need to see your test data!

OK Ray quite possibly I was just thinking beyond the current project so don't have any data
