is_dir() and ch_dir, oh my!

[aezell]

I am super rusty in PHP after teaching English for two years and I don't think I knew how to do this before. So, please help me learn and understand.

I need to take a directory like: $saveDir = "c:/home/www/temp/"
and then drill down through whatever directories might be in it until I get to a directory with only files.

I am certain that a directory will contain either 1) another directory or 2) files. The goal eventually is to get down to the files and then copy them to some other place, but drilling down through the possible directories and checking for new directories or files is where I am stumbling.

My pseudocode thinking is this:

foreach ($item) {
  if(is_dir($item)) {
    ch_dir($item);
} else {
    parse_dir($item); // <- not sure how to use this function
  }
}

Something like that, but I honestly don't have much clue past that.

TIA!

There is no parse_dir() function native to PHP, have you considered using the Directory Functions?

yeah, I just realized I wrote that. I meant readdir() or something like that.

Here's where I am at now, though out of context, it might be a touch confusing. The course_id and session_id are items that the files belong to, so sort of overlook that.

function digDirectory ($handleDir,$course_id,$session_id) {
    $permSaveDir = $this->config["htmlRootDir"]."/courses/".$course_id."/".$session_id;
    if ($handle = opendir($handleDir)) {
        while (false !== ($file = readdir($handle))) {
            if (!is_dir($file)) {
                rename($handleDir . "/" . $file,$permSaveDir . "/" $file);
            } else {
                $this->digDirectory($file,$course_id,$session_id);
            }
        }
        closedir($handle);
    }
    return true;
}
