Alphabetical order? Help!

If you've read some of my earlier posts, you know I'm a newbie at PHP, so now im stuck at a point, and I'd like to see if anyone has a suggestion.

Ok, here is the problem...i have a text file on the server, and in it are listed lines like this:

01|Brescello|stadium|city|
02|Aglianese|stadium|city|
03|Casteldisangro|stadium|city|

and the following code is part of a php file that creates a form.

<SELECT NAME="home">
<?php

include ("C:pathtoconfig.php");

$fd = fopen ($teams, "r");
while (!feof ($fd))
{
$readlines = fgets($fd, 4096);
$squads = explode("|", $readlines);
if ($squads[1] == "Florentia Viola") {
echo '<OPTION SELECTED VALUE="'.$squads[0].'">Florentia
Viola</OPTION>'."n";
} else {
echo '<OPTION VALUE="'.$squads[0].'">'.$squads[1].'</OPTION>'."n";
}

}
fclose ($fd);

?>
</SELECT>

What is does is create options in a dropdown menu. Right now the outputted
HTML would be

<OPTION>Brescello</OPTION>
<OPTION>Aglianese</OPTION>
<OPTION>Casteldisangro</OPTION>

Problem is that I would like it alphabatized, like so:

<OPTION>Aglianese</OPTION>
<OPTION>Brescello</OPTION>
<OPTION>Casteldisangro</OPTION>

so aftter looking around a bit in the manual, I see this:

<?php

$order = array ($squads[1]);
sort ($order);
reset ($order);
while (list ($key, $val) = each ($order)) {
echo "order[".$key."] = ".$val."n";

?>

so the array $order is declared, then is sorted. To me that means that I
have to declare each fruit in the array. In my array $squads in the example
below [0] is id number [1] is team name [2] is stadium and [4] is city. I
want to alphabatize only the team name i.e. $squads[1] then after the team
name is alphabatized (sorted) then the if...else statement is run ... so
this is what i tried

<html>
<body>
<select>
<?php

include ("C:pathtoconfig.php");

$fd = fopen ($teams, "r");
while (!feof ($fd))
{
$readlines = fgets($fd, 4096);
$squads = explode("|", $readlines);
$order = array ($squads[1]);
sort ($order);
reset ($order);
while (list ($key, $val) = each ($order)) {
if ($squads[1] == "Florentia Viola") {
echo '<OPTION SELECTED VALUE="'.$squads[0].'">Florentia
Viola</OPTION>'."n";
} else {
echo '<OPTION VALUE="'.$squads[0].'">'.$squads[1].'</OPTION>'."n";
}
}

}
fclose ($fd);

?>
</html>
</body>
</select>

I still get the same result as before.
What am I doing wrong??

Thanks again

RE: Alphabetical order? Help!

i think it'd be much easier for you if you created a multi-demensional array as follows, and then had a look at the multi-sort function.

php Code:

Original - php Code
<?php include("C:pathtoconfig.php"); $lines = file("$teams"); for($i=0; $i<count($lines); $i++) { $squads[$i] = explode("\|", $lines[$i]); } // now $squads[0][0] = 1st id // $squads[0][1] = 1st title // $squads[1][0] = 2nd id etc.. ?>

 
<?php
 
include("C:pathtoconfig.php");
 
$lines = file("$teams");
for($i=0; $i<count($lines); $i++)
{
    $squads[$i] = explode("|", $lines[$i]);
}
 
// now $squads[0][0] = 1st id
// $squads[0][1] = 1st title
// $squads[1][0] = 2nd id etc..
 
?>
