[SOLVED] natcasesort help

[thewooleymammoth]

can anyone tell me why this isnt working???? tried it on wamp and server and for some reason the natcasesort() is just sorting it like sort() would

<?php
$dir=$_GET['dir'];


$img= scandir("$dir/");
natcasesort($img);
  $num=2;

echo"<center><table align='top' BGCOLOR='#CCCC99' cellspacing='60'><tr valign='top'><td>";
   while ($img[$num]!= null)
   {
    echo "<a href='display.php?num=$num&dir=$dir'>$img[$num]</a><br>";
    if ($num2 >= 1500)
    {
     echo "</td><td>";
     $num2=0;
    }
    $num2++;
    $num++;
   }
?>

 

ive got a link to it on my server http://fatalinjury.org/list.php?dir=pics notice lowercase letters start about half way down the list

<?php

include('menu.php');
$dir=$_GET['dir'];


$img= scandir("$dir/");
natcasesort($img);
  $num=2;
  $num2=0;

echo"<center><table align='top' BGCOLOR='#CCCC99' cellspacing='60'><tr valign='top'><td>";
   while ($img[$num]!= null)
   {
    echo "<a href='display.php?num=$num&dir=$dir'>$img[$num]</a><br>";
    if ($num2 >= 1500)
    {
     echo "</td><td>";
     $num2=0;
    }
    $num2++;
    $num++;
   }
    echo "</tr></td></table></center>";
?>

 

sorry there is the right code

The keys of the array are not changed, so when you iterate using an incrementing key, you get the original array order.

 

I recommend using a foreach() loop instead of using the $num counter in a while loop.

hmm well i dont really understand why using a foreach loop worked better than the other way but it works with a foreach loop haha thanks a million been rippin my hair out

[thewooleymammoth]

since ive fixed this problem, the scardir adds in . and .. for the first two pieces of the array, how do i get rid of that?

why wouldnt it be changing the order of the keys?

You should probably read the php manual page for the function you are using to learn what the function does and does not do.

i realize it doesn't change the keys, but why doesnt it? is there an advantage to keeping the keys? and also is there an alternative to make it so it does change the keys cause my site runs on the basis that the keys will line up

after a while of reading through the comments on http://www.php.net/natcasesort if found a comment about array_values() which solved my problem thanks for the help though
