readdir() alphabetically

[borninblood]

I was wondering if someone could help me - basically I had some code which worked fine on another server, but on my new eukhost server is performing well somewhat odd.

Basically I am using the readdir() function to read in thumbnailed images and the link to their full sized counterparts.

A simple enough procedure, and on the old server it would do this fine, it would read them alphanumerically from the lowest to highest, however on this new server it is reading them in some bizarre order that I can't really work out.

Is there any way to force the code to read a certain way? (I couldn't find such a parameter) or is there anything else I could do?

I suppose if all else fails, I fire everything into an array, sort the array and then output the results, but I really don't want to have to do that if it can be avoided.

Here is the code I am using...

PHP Code:

$j = 0;
$gall = $_GET['gall'];
$test = "/home/simplyti/public_html/members/i/$gall/";
$dir = opendir($test);

while ($file = readdir($dir)) 
{

 if ($file != "." && $file != ".." && $file !="index.php") 
 {
     if(eregi("t[.]jpg", $file)) 
     {

      $limage = explode("t.", $file);
      $linkimage = "$limage[0].$limage[1]";
            if ($j==3)
            {
            print "<tr>";
            $j = 0;
            }
        
      print"<td><div align='center'><a href='http://www.simplytied.com/members/i/$gall/$linkimage' target='_new'><img src='http://www.simplytied.com/members/i/$gall/$file' border='0' /></a></div><td>";
    $j++;

    }
  }
}
   closedir($dir); 


Any help would be greatly appreciated!

This from the php manual

readdir

(PHP 4, PHP 5)

readdir — Read entry from directory handle
Description
string readdir ( resource $dir_handle )

Returns the filename of the next file from the directory. The filenames are returned in the order in which they are stored by the filesystem.
Parameters

dir_handle

The directory handle resource previously opened with opendir().

Return Values

Returns the filename on success, or FALSE on failure.

Looks like you will have to load it into that array after all - sorry

Haha, yeah I seen that but prayed someone had came up with an easy way around it.

I bloody hate arrays!

Cheers!

Well perhaps i could have been a bit more helpful, so try this:

$j = 0;
$linkimage=array();
$linkfile=array();
$gall = $_GET['gall'];
$test = "/home/simplyti/public_html/members/i/$gall/";
$dir = opendir($test);



while ($file = readdir($dir))
{

if ($file != "." && $file != ".." && $file !="index.php")
{
if(eregi("t[.]jpg", $file))
{

$linkfile[$j]=$file;
$j++;
}
}
}
$j=0;
print "tr>";
sort ($linkimage);
$k=count($linkimage);
for ($i=0;$i<$k;$i++) {
$limage = explode("t.", $linkfile[$i]);
$linkimage = "$limage[0].$limage[1]";
if ($j==3)
{
print '/tr>tr>';
$j = 0;
}

print 'td>div align="center">a href="http://www.simplytied.com/members/i/$gall/$linkimage" target="_new">img src="http://www.simplytied.com/members/i/$gall/$linkfile[$i]" border="0" />/a>/div>td>';
$j++;

}
}
}
closedir($dir);
print "/tr>";

or something like that
Regards

Ps had to edit it cos the [code] tags messed up the code - I removed all the < from the print lines to get it to display properly

[borninblood]

Haha, much appreciated! Thank you!

I was about to start writing my own, which would have been pretty much that but hey! cheers dude!
