this doesn't work-

The only difference is one is in a directory and one is not, here is the code-

<?php
if(!function_exists('scandir'))
{
   function scandir($dir, $sortorder = 0)
   {
       if(is_dir($dir))
       {
           $dirlist = opendir($dir);
           
           while( ($file = readdir($dirlist)) !== false)
           {
               if(!is_dir($file))
               {
                   $files[] = $file;
               }
           }
           
           ($sortorder == 0) ? asort($files) : arsort($files);
           
           return $files;
       }
       else
       {
       return FALSE;
       break;
       }
   }
}
function dirlist($dir) {
   foreach(scandir($dir) as $entry)
       if($entry != '.' && $entry != '..')
       {
           $entry  = $dir.'/'.$entry;
           
               $path = pathinfo($entry);
               $listarray[] = $path['basename'];
       }
   return($listarray);
}


$arr = dirlist("/kunden/homepages/15/d161670145/htdocs/__puretricks/videos");
foreach ($arr as $value)
{
if (is_dir("/kunden/homepages/15/d161670145/htdocs/__puretricks/videos/".$value))
{
$value2 = preg_replace('/_/',' ',$value);
echo $value2."<BR>";
}
}
?>

PHP:

Why?

 

ok, I found out what works in both but now I am not sure how the previous code ever worked-

 

Define "doesn't work". Is there an error, no output/blank page?

 

There was no output
