Directory listing with file info

[Kim Jensen]

I'd like to make a directory listing where instead of the entire
filename I need it to show the filename minus the extention and get the
value of charname= in the file itself.

I've been told that I had to turn the directory listing into an array
and then use "foreach (array as item)" to go through and open each file
but I've tried several different approaches and I just can't get it to work.

I've been able to make it list the directory in order using this script
but after that I'm lost.

<?
$list = Array();
$handle = opendir('testdir/.');
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
$list[] = ($file);
}
}
closedir($handle);
sort ($list);
reset ($list);

while (list ($key, $val) = each ($list)) {
echo "<a href=test.php?name=$val>$val</a><br>";

}
?>

Here I'd like the $val after the name= to be just the filename without
the extention (all files in the directory are txt files) and then the
second $val which it shows in the list to be the value of the line
charname= in the txt files themselves.

Anybody have an idea what I should do?

Try this:

<?
$list = Array();
$handle = opendir('../');
while (false !== ($file = readdir($handle))) {

$fileparts = explode(".",$file);
if (count($fileparts) > 1) {
array_pop($fileparts);
}
$file = join(".",$fileparts);

if ($file != "." && $file != ".." && $file != "") {
$list[] = $file;
}
}
closedir($handle);
sort ($list);
reset ($list);

while (list ($key, $val) = each ($list)) {
echo "<a href=test.php?name=$val>$val</a><br />";

}

?>

Are you really sure you want to do that?
You have top open each and every file, read/print its contents, and close
the file. It might be a lot slow!

foreach ($list as $val) {
$f = fopen($val);
while (!feof(f)) {
$line = fgets($f);

'">', $matches[1], '</a><br>';
break; /* leave inner while() */
}
}
fclose($f);
}

This method, though, assumes that all extensions are exactly three
characters long.

What about extensions such as pl, py, h, among others?

The problem is that the filenames themselves even if they contain the
name I'm looking for aren't really pleasing to the eye as links.

I'd rather have links that read:

Angelina Jolie
Gwynneth Paltrow
Jude Law
Michael Gambon
Sir Lawrence Olivier

than

angelinajolie
gwynnethpaltrow
judelaw
lawrenceolivier
michaelgambon

Sorry, just got home from watching Sky Captain :)

Just forgot something. If I was just now creating the whole thing I
could easily use the first examples as file names, but unfortunately I
already have thousands of links using the second type of file names so
going back and changing all of them manually or even by global
search/replace would take ages.

Yes, as the OP stated.

In this case, it didn't seem necessary to make a generic function -- but
I agree that would have been a better option from the start :)

About the slowness. Couldn't it be done so that it only took the files
starting with a specific letter?

So that if I want to see a listing of the files starting with A I'd open
dir.php?letter=a

Write a script to do that for you!

<?php
$oldfiles_dir = 'old/';
$newfiles_dir = 'new/';

foreach ($list as $val) {
/* get $charname :: fopen(), fgets(), fclose() */
copy($oldfiles_dir . $val, $newfiles_dir . $charname);
}

?>

And presto! :-)

What about
filename.with.a.lot.of.dots
and
filename_without_dots
?

:-)
The generic function would have to deal with them!

Or you could make a 'index' file and only open that one. Its contents
would be something like:

angelinajolie.txt Angelina Jolie
gwynnethpaltrow.txt Gwynneth Paltrow
judelaw.txt Jude Law
lawrenceolivier.txt Sir Lawrence Olivier
michaelgambon.txt Michael Gambon
Or use a database.
Of course these options assume the 'index' file and the database would
be updated for every new file ... (and deletions and changes).

The code i posted earlier should work with that...

Heh. That's the problem with having a split personality. Sometimes you
forget which is which :)

Kim Jensen or was that Tenzel Kim???

I was trying to avoid using a database for now, as I know that if I went
ahead with that, it would end up being so huge in scope that I'd never
finish it :)

I have been considering the index file approach. However, considering
the speed problem is mainly a problem I don't want my visitors to
encounter making the slow "grab the info from all the files" version
could be done on my harddrive and the output of the script I could just
copy and paste into an index page. That way the slow stuff will be done
behind the scenes.

Maybe that's the best option. Hadn't considered that until just now.
