Topic awaiting preservation: Order Alphabetically (sp?) (Page 1 of 1)

Hello! we made this code here, to show all the files from a dir and its subdirs:

<?php



function getDirList ($dirName) { 

$counter = 0;

$d = dir($dirName); 

while($entry = $d->read()) { 



if ($entry != "." && $entry != "..") { 

if (is_dir($dirName."/".$entry)) { 

getDirList($dirName."/".$entry);



} else { 

if (preg_match("/html\$/i", $entry)) 

	{ 

	echo "<a href=$dirName/$entry>$entry</a><br>"; 

	} 

} 

} 

} 

$d->close(); 



} 

getDirList("../thumbespos"); 

echo "</tr></table></TD> </TR></TABLE>";

?>

Is it possible to order it alphabetically?

I mean, the files! not the subdirs! (the subdirs are not listed, but it shows the files in order as it reads the subdirs)

1. Collect all files in array (instead of showing them directly on screen)
2. Sort array (using sort() function)
3. Print array contents

Okies, I made it cool!
a could get the array (even when I hate arrays ) I could print it, but I couldn't sort it!
I checked the manual and the functios it's : SORT($array);

I was getting the array like this:
$a = array($entry);

And then, I printed the array:
for ($i = 0; $i < count($a); $i++) {

echo("$a[$i]<br>");
}

It prints cool.

But when I add the SORT($a); (right before the for loop) it gives me an error:
Warning: sort() expects parameter 1 to be array, null given in path/to/file.php on line xxx (teh SORT line)


Wakkos
follow the white rabbit

what does the code on the 'SORT' line say?

is it an array or a string?

remember that it's telling you it's going to need an array... the kind that are defined with '@' as opposed to strings, which are defined with '$'...

I would have to wonder about how you are getting your array. I'm not saying that I know for sure there's anything wrong with it, but I've never done it that way.

Why don't you try something like this:

$a = array(); //Create empty array

Then in your while loop you can add $entry to your array like this:

array_push($a, $entry); //adds $entry to your array

Then you should be able to sort($a).

Wakkos, here's the complete working code...

<?php

// Written by mr.maX, http://www.max.co.yu/

/*

get_folder_List() function description

$folder - starting folder
$extensions - list of all file extensions
$entries - array where to store files (stored like this "filename

Wow!!! that's a great code mr.maX! thanks a lot for your time!!
Pretty weet!
butcher, I tried yours, but even with that, it prints an unsorted array...
