readdir with limits?

[Anon]

Hi,

I have a script that can read a directory (of images in this case) and then display all the filenames or images on a page. This is all fine until I get a very large number of files in the directory....

Here's my question: how would I go about making a limit so that the script only displays the first, say, 20 files and then makes links to the next 20 and so on... Its much like the limiting of database results but I haven't been able to work it out yet.

Thanks for any help.

There was a similar question 1 or 2 weeks ago.
You can find the question in the phorum.
So you can find the answer too.

Good Luck.

You could probably read the directory and put all the file anmes into an array. then get the count of the array. This would be starting point for how many pages you will have.
I wrote this little bit of code which seems to work pretty good:
Change $recperpage to the number of images you want to display on one page

<?php
if (!isset($offset)) $offset = 0;
$recperpage = 5;

$dir = dir(".");
$dir->rewind();
while ($file = $dir->read()) {
if (is_file($file) && (($file != ".") && ($file != ".."))) {
$filelist[] = $file;
}
}
$count = sizeof($filelist);

for ($i=$offset; $i <= ($offset + $recperpage); $i++) {
sort($filelist);
print $filelist[$i] ."<br>";
}

$newoffset = ($offset + $recperpage);
$prevoffset = ($offset - $recperpage);

if ($offset < ($count - $recperpage)) {
printf('<a href="%s?offset=%s">Get next %s images</a><br>', $PHP_SELF, $newoffset, $recperpage);
}

if ($offset >= $recperpage) {
printf('<a href="%s?offset=%s">Get last %s images</a><br>', $PHP_SELF, $prevoffset, $recperpage);
}
?>
