Sorting words from a textfile

Qben

I would like to print the second word at each row of this textfile in alphabetical order:

misc|White Bead|bead_white
misc|Yellow Bead|bead_yellow
food|Beer|beer
misc|Beer Glass|beerglass
quest|Bees Wax|beeswax
bones|Big Bones|bigbones
tools|Big Net|bignet

like this:

Beer
Beer Glass
Bees Wax
Big Bones
Big Net
White Bead
Yellow Bead

how can i do that?

steps

Ok, maybe this could be done via one regexp, but I'm not really familiar with that, so here's the long way:

read the file into a string via file_get_contents(),
use explode to split the string by '|',
push the 2nd, 5th, 7th ... element of the resulting array in another array,
use a sort function to sort this array.

You have to know a text file is written to an array after fread. After this u can splitt this array and use "sort" as function.

Ok thanks for answers, but im gonna loop the items out in a table like this:

<?php
$itemfile = file("txts/items.txt");
$rows = count($itemfile);
?>
<table>
<?php
$i = 0;
while($i < $rows) {
 $item = explode("|", $itemfile[$i]);
 $class = $item[0];
 $name = $item[1];
 $img = $item[2];

 if($_POST['class'] == "displayall") {
  echo("
  <tr>
  <td width=\"0%\"><img src=\"pictures/items/".$img.".gif\" border=\"1\"></td>
  <td><font size=\"2\" face=\"Verdana, Arial, Helvetica, Sans-Serif\">".$name."</font></td>
  </tr>
  ");
 } else {
  if($class == $_POST['class']) {
   echo("
   <tr>
   <td width=\"0%\"><img src=\"pictures/items/".$img.".gif\" border=\"1\"></td>
   <td><font size=\"2\" face=\"Verdana, Arial, Helvetica, Sans-Serif\">".$name."</font></td>
   </tr>
   ");
  }
 }

 $i++;
}
?>
</table>

i think i can sort them if i put the item names before the item classes.. but then its over 1500 rows to edit...
