I'm just starting to explore the concept, but I, just today, made an index.php page that read the contents of a directory (all different kinds of images) and wrote code around them. Since there were over 80 images, this saved me a WHACK of time. I had them write the JavaScript for the rollovers, too.

Very interesting.

I am seeing all sorts of faster development coming.

Thanks for the links, Mark, too. My goal was to learn PHP while on maternity leave, but the maternity leave isn't really happening, so I'll have to learn it on the job.

Yes, there are grep functions. PHP doesn't function the same way PERL does with regex. PHP requires you to put your regex in a function (whereas in perl, practically anywhere will do).

PHP Docs:
ereg(), ereg_replace(),
eregi(), eregi_replace()

LXXXIV. Regular Expression Functions (Perl-Compatible)
preg_match(), preg_match_all(), preg_replace()

You don't really need PHP or PERL to filter files...

<?php
$command = \"ls -w1 \" . $dir . \"/*.htm* | awk 'BEGIN {FS=\\\"/\\\"} {print \\$NF}'\";
exec($command, $dir_list);

foreach ($dir_list as $file) {
    $file_list .= '<li><a href=\"' . $file . '\">$file</a></li>\n';
}
?>

I'm doing something similar to parse out map files for my WAHL project. I wrote a shell script a while ago to do this kind of stuff, and now I'm copy & pasting it into my PHP.

How so?

I'm intrigued!

Of course, I'm also just learning (duh!) so talk in small words.

You could probably optimise that code a fair way, if you wanted to. There's no grep function in PHP?

That does help a bit, doesn't it?

got it!

while ($file_name = readdir($dir)) {
if (($file_name != ".") && ($file_name != "..") && ($file_name != "index.php")) {
$file_list .= "

$file_name

\n";
}

Make sure the freaking variable is right! Argh.
