[Resolved] Help with sort

[banpro]

Hi, I'm trying to use sort to alphabetize a listing of names but I'm having trouble with the functions. I need to open the list, read it into an array, sort it and then rewrite the list in alphabetic order. Here's what I have but it isn't working as expected.

//Alpha sort the directory
     $fpp = fopen("listing.php", 'r');
     while(!feof($fpp))
        {
        $line = fgets($fpp, 1024);
        }
      fclose($fpp);
      sort($line);
      reset($line);
// Rewrite the directory      

      $ffpp = fopen("listing.php", 'w');
      fwrite($ffpp, "$line");
      fclose($ffpp);

Any ideas or suggestions are most welcomed and appreciated.

Thanks in advance,
Scott

what isn't working, what is working, what is displayed, where do you "think" it isn't working, etc...

It hangs on the sort() & resort() commands with the folowing errors:

Warning: sort() expects parameter 1 to be array

Warning: reset(): Passed variable is not an array or object

I'm assuming that this part:
while(!feof($fpp))
{
$line = fgets($fpp, 1024);
}
isn't working as I understand it should. I expected this to read the directory listing line by line, giving me an array to then sort but it doesn't seem to do that.

Thanks,
Scott

try echoing something like this

echo $line[5];

[stolzyboy]

if that doesn't work, try replacing this

$line = fgets($fpp, 1024);

with this

$line[] = fgets($fpp, 1024);

Okay, I seem to have the reading part worked out, but when I try to write the sorted list back to the file all I get is the single word "Array". Here's what I have so far:

//Alpha sort the directory 
     $fpp = fopen("listing.php", 'r'); 
     $x = 0; 
while(!feof($fpp)) { 
        $line[$x] = fgets($fpp, 1024); 
        $x++; 
} 
      fclose($fpp); 
      sort($line); 
      reset($line); 

// Rewrite the directory      

      $ffpp = fopen("listing.php", 'w'); 
      fwrite($ffpp, "$line"); 
      fclose($ffpp);

Thanks again for the ideas and suggestions,
Scott

put this

$line = implode("<br>", $line);

before this

fwrite($ffpp, "$line");

and see what that gets ya

Thanks for all the suggestions. I've tried to mark this thread as resolved but the link seems to do nothing???

Anyway, I was able to print the variables from the array in their sorted order by using the following (posted for others who ight find it of use):

      foreach($line as $new_line) { 
           fwrite($ffpp, "$new_line\n"); 
      } 

Thanks all,
Scott
