[Resolved] need help to sort ouput from "readdir"

[chroot]

I've never ever touched PHP, so I'm sure I've done this the least efficient way possible, however it works, except for one slight "problem"; I would like to print the directories in alphabetic order. This has proven to be quite difficult for “PHP-challenged” (me), could anyone please help me out?

(The script below is pretty much a cut-paste from the various PHP-man pages with some slight modifications🙂

<?php 
//define the path as relative
$path = "/";

//using the opendir function

$dir_handle = @opendir($path) or die("Unable to open $path");

//running the while loop

$dir_handle=opendir('.'); 
while (false!==($file = readdir($dir_handle))) { 
    if ($file != "." && $file != ".." && $file != "index.php~" && $file != "index.php" ) { 




echo "
<div align=center>
<TABLE width=80% border=1 bordercolor=#999999 bgcolor=#aaaaaa>
	<TR>
	<TD width=95 valign=top>";}
if ($file != "." && $file != ".." && $file != "index.php~" && $file != "index.php") { 
	 echo "<img src=$file/$file.jpg> 
	</td>
	<TD valign=top>";}


if ($file != "." && $file != ".." && $file != "index.php~" && $file != "index.php") {
		readfile("$file/$file.txt");}
	echo "</TD> 
	</tr>
</TABLE>
<br>
</div>";       


}
//closing the directory
closedir($dir_handle);

?>

Thanks in advance!

why r u doing?

$path = "/";

//using the opendir function

$dir_handle = @opendir($path) or die("Unable to open $path");

//running the while loop

$dir_handle=opendir('.');

u need just the last line
$dir_handle= ...

of the first 2 lines
$path=...
$dir_handle=@...

but not both.

// fill an array with all items from a directory
$path = "./";
$handle = opendir($path);
while ($file = readdir($handle)) {
    $files[] = $file;
}
closedir($handle); 
sort($files);
reset($files);

while ($files as $k => $file) { 
    if ($file != "." && $file != ".." && $file != "index.php~" && $file != "index.php" ) { 

echo "
<div align=center>
<TABLE width=80% border=1 bordercolor=#999999 bgcolor=#aaaaaa>
    <TR>
    <TD width=95 valign=top>";}
if ($file != "." && $file != ".." && $file != "index.php~" && $file != "index.php") { 
     echo "<img src=$file/$file.jpg>
    </td>
    <TD valign=top>";}


if ($file != "." && $file != ".." && $file != "index.php~" && $file != "index.php") {
        readfile("$file/$file.txt");}
    echo "</TD>
    </tr>
</TABLE>
<br>
</div>";       


}

Thanks for your reply jayant, this is my very first attempt on PHP, but I think I'm beginning to like it.
This is what I ended up with:

<?php 
//define the path as relative to webroot
$path = "/htdocs";

//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");

//running the while loop to put the directories on the stack (array), ready for manipulation
while ($file = readdir($dir_handle)) {
    $files[] = $file;
}

//Close directories and sort files in a decending order
closedir($dir_handle); 
sort($files);
reset($files);

foreach ($files as $k => $file) { 
    if ($file != "." && $file != ".." && $file != "index.php~" && $file != "index.php" ) { 




echo "
<div align=center>
<TABLE width=80% border=1 bordercolor=#999999 bgcolor=#aaaaaa>
	<TR>
	<TD width=95 valign=top>";}
if ($file != "." && $file != ".." && $file != "index.php~" && $file != "index.php") { 
	 echo "<img src=$file/$file.jpg> 
	</td>
	<TD valign=top>";}


if ($file != "." && $file != ".." && $file != "index.php~" && $file != "index.php") {
		readfile("$file/$file.txt");}
	echo "</TD> 
	</tr>
</TABLE>
<br>
</div>";       


}
