PHP - Iterate through folders and display HTML contents

Question

I\'m currently trying to develop a method to get a overview of all my different web templates I\'ve created and (legally) downloaded over the years. I thought about displayi

glob('*.html') will work if they're all in one directory.

If you want to walk a file tree -- checking everything in the current directory and in subdirectories and subdirectories of subdirectories (etc) -- then you have a couple of options.

One would be to use the unix find command with one of the methods of PHP system invocation. Something like:

find <search_root_dir> -name "*.html" -print

will get you output that looks something like

search_root_dir/blah.html
search_root_dir/foo.html
search_root_dir/subdir/baz.html
search_root_dir/subdir/bah.html
...

Another thing you could do is write a recursive function that uses chdir and readdir or maybe scandir, something like:

function dir_walk($start_dir,$func) {
    $entries = scandir($start_dir);
    foreach($entries as $entry) {
        if($entry == '.' || $entry == '..') {
            /*skip these*/
        } else if(is_dir($entry)) {
            dir_walk($start_dir.'/'.$entry,$func);
        } else $func($start_dir.'/'.$entry);
    }
}

Then, write another function:

$html_files = array();
function record_html_files($filename) {
   global $html_files;
   if(strpos($filename,'*.html') === (strlen($filename) - 6))
     $html_files[] = $filename;
}

And call it like this:

dir_walk('/path/to/search/root','record_html_files');

Or, write dir_walk so it accepts an object with a method call you can make inside. There's some variations possible here.
