Re: [PHP] sort()-help needed
Put them into an array and sort() the array. The loop through the sorted
array and output at that point.

Just what I try. But, because of my lack of understanding, the output is my
problem:
function createLinks() {
$p = 0;
$handle=opendir(.);
echo UL\n;
while ($file = readdir($handle)){
$files[] = $file;
$sorted = sort($files);
if (($file == .) || ($file == ..) || ($file == basename ($PHP_SELF)))
{ continue; }
if(is_file($file)) {
$p++;
$linktext = ucfirst ($file);
$linktext = substr_replace ($linktext,'',-4);
echo LIA HREF=\$file\$linktext/A\n;
}
for($i = 0; $i $p; $i++) {
//something here
}
echo /UL\n;
return true;
}

You're not doing what has been suggested above. See comments below.
1) In your while loop only read in the filenames into an array (discarding '.'
and '..').
2) Then sort the array.
3) Then use a foreach to loop through the array elements to create the links.
function createLinks() {
$p = 0;
$handle=opendir(.);
echo UL\n;
while ($file = readdir($handle)){
You've read in a filename
$files[] = $file;
And added it to the array
$sorted = sort($files);
Then sort the array, but why? You haven't read in ALL the files yet so why
sort now? Also you're not using the results of the sorted filenames ($sorted)
anywhere else in your code.
