asort() help please

ntlab

Hello All,
I have been having trouble with the asort(). I have read the directions and array stuff but I am still not able to get it to work correctly. Here is the code I am using:

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

$stripper = preg_replace("/_/"," ","$file");
echo "$stripper\n";
}
}
closedir($handle);
}

I want to sort the $file and I have tried $file[]=$stripper asort($stripper) and there is one directory that is still not in order. Perhaps it is a setting with apache? Because in Windows it does not display the directories out of order. ??? Any help would be appreciated.

try something like this:

$myFiles = array();
if ($handle = opendir('.')) 
{ 
  while (false !== ($file = readdir($handle))) 
  { 
    if ($file != '.' && $file != '..' && $file != 'index.php') 
    { 
      $stripper = preg_replace("/_/"," ", $file); 
      $myFiles[] = $stripper;
    } 
  } 
  closedir($handle); 
} 
asort($myFiles);
foreach($myFiles as $val) echo $val . '<br/>';

Have a look at natsort() as well.
Its sorts it like a human would.

Thank you so much for your help. The sorting worked perfectly. However I was also using $file in its raw form which were directories with underscores. When I use the "foreach ($myfiles as $var) and then use <a href="$val">$val</a> I get the directories without the underscores which make the links not work. Is there a way to use the $file before it is stripped of the underscore and still use the $myfiles. I have tried creating a $myfiles2[] = $file2 and feeding the $myfiles2 into it such as <a href=\"$myfiles2\">$myfiles</a>but I keep getting "Array" as the link.

I didn't understand the bit about the underscores. Why were you removing them in the first place?

What happens when you leave them in?

Are underscores the way you know it's a directory and therefore you don't want them on the list. Better to use the underscore in an if () then and only add to the array if there isn't one.

You could probably just add:

$unstripper = preg_replace("/ /","_", $val);

after the foreach and before the echo.

ie:
foreach($myFiles as $val) {
$unstripper = preg_replace("/ /","_", $val);

echo $unstripper .'</br>';
}

The solution that you proposed worked perfectly. Sarahk, The directories that I was listing had underscores in them and I wanted to strip the underscores from them for "pretty'' purposes. I wanted to use the raw $file information as the href and $val information as the display. Thanks again to all for your help.
