PHP readdir(): Sort results alphanumerically
I use the attached code to return a list of directories. How can I display the results sorted alphanumerically?
if ($handle = opendir('directory')) {
while (($file = readdir($handle)) !==false) {
if (substr($file,0,1) != "." && is_dir($file)) {
echo $file;
}
}
closedir($handle);
}

@hankknight: Here is a man page worth reading as you choose the exact kind of sort you need.

I think ksort may be better?
<?php
$directory = new directoryListing("../testfolder");
print_r($directory->sortListing());
class directoryListing {
private $_dPath;
private $_listing = array();
public function __construct($path) {
$this->_dPath = $path;
}
private function getListing() {
if ($handle = opendir($this->_dPath)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != ".." && !is_dir($file)) {
$this->_listing[] = $file;
}
}
closedir($handle);
}
}
public function sortListing()
{
$this->getListing();
ksort($this->_listing);
return $this->_listing;
}
}
?>

There are only numbered keys in the arrays we built here, so the sort order with ksort will not change.

Hi Ray,
Sorry, sort does work fine, it must of been the folder structure I was testing it on, one thing I did find was wrong in the previous examples was that is_dir($file) needs to be ! is_dir($file) as it was not returning any listings.

I think the OP wanted to sort a list of directories. That is probably why we found is_dir() in his original post.
Yep, know that , that what the class returns...
