I need to sort php jquery gallery script alphabetically

Question

know nothing about php, but I have this script that reads a folder and displays a thumbnail gallery, problem is it dosent display alphabetically. Have searched the net and seen that sort does this but have no idea where to start any help would be much appreciated.

heres the script

$sitename = $row_wigsites['id'];     
$directory = 'sites/'.$sitename.'/pans';
$allowed_types=array('jpg','jpeg','gif','png');
$file_parts=array();
$ext='';
$title='';
$i=0;

$dir_handle = @opendir($directory) or die("There is an error with your image directory!");

while ($file = readdir($dir_handle)) 

{

if($file=='.' || $file == '..') continue;

$file_parts = explode('.',$file);
$ext = strtolower(array_pop($file_parts));

$title = implode('.',$file_parts);
$title = htmlspecialchars($title);


$nomargin='';

if(in_array($ext,$allowed_types))
{

    if(($i+1)%4==0) $nomargin='nomargin';

    echo '
    <div class="pic '.$nomargin.'" style="background:url('.$directory.'/'.$file.') no-repeat 50% 50%;">
    <a href="'.$directory.'/'.$file.'" title="Panoramic Stills taken at '.$title.'°" rel="pan1" target="_blank">'.$title.'</a>
    </div>';

    $i++;
}
}

closedir($dir_handle);

Answer 1

add the sort line as given below

$file_parts = explode('.',$file);
sort($file_parts) or die("sorting failed");
$ext = strtolower(array_pop($file_parts));

Answer 2

It's probably easiest to put the values from the files into an array, then sort the array before outputting it to the page.

Answer 3

Try using glob instead of opendir, something like:

$i=0;
foreach (glob($directory.'/*.{jpg,jpeg,png,gif}', GLOB_BRACE) as $file){
    if($file=='.' || $file == '..') continue;
    $file_parts = explode('.',$file);
    $ext = strtolower(array_pop($file_parts));
    $title = basename($file);
    $title = htmlspecialchars($title);
    $nomargin='';
    if(($i+1)%4==0) $nomargin='nomargin';
    echo '
    <div class="pic '.$nomargin.'" style="background:url('.$file.') no-repeat 50% 50%;">
    <a href="'.$file.'" title="Panoramic Stills taken at '.$title.'°" rel="pan1" target="_blank">'.$title.'</a>
    </div>';
    $i++;
}

Glob should return sorted list of files.

EDIT: Thanks to Doug Neiner for a tip ;)
