Listing information about all folders in directory

[Skier88]

I'm trying to create a page that automatically loads links to the index pages of its subfolders. I have written this:

$dir = opendir(".");
while($file = readdir($dir))
if(strrpos($file,".")===false)
echo("<a href='$file'>$file</a><br />");

Which successfully finds all the folders I want to display, and displays links to them.

What I want to do is change the content of the link (currently the folder name) to the title of the page (not the <title> element in the head, but the first <h1> element in the body). Obviously I cannot load all of the pages. My priorities are for it to be 1) fast/efficient, 2) automatic, and 3) space efficient. I am willing to introduce name/id tags, but I would like to avoid creating an file listing the folders for the simple reason that it would not automatically and instantaneously update.

Any suggestions?

On second thought, just getting the <title> elements in the head of each page would be OK but not preferable, as they could be edited to yield the desired result.

I found the answer. Since the first line was a PHP function including the page title, I could simply use fgets and display the appropriate substring.

lol.. yeah, well thanks for reading anyway. I probably should have looked a bit longer before asking for help.
