Sorting a list?

[Cobalt.Board]

Hey, I need help! I have the following bit of code:

$delimiter="\t";
$lines=file($settings['logfile']);
list($name,$from,$email,$url,$comment,$added,$isprivate,$reply)=explode($delimiter,$lines[$num]);

 

I need to sort that list numerically by the $comment variable. How do I do this?

[MadTechie]

try this

<?php
$delimiter="\t";
$lines=file($settings['logfile']);
foreach($lines as $K => $line)
{
$lines[$K] = explode($delimiter,$line);
}

usort($lines, "cmp");

foreach($lines as $K => $line)
{
list($name,$from,$email,$url,$comment,$added,$isprivate,$reply)= $line;
echo "$name,$from,$email,$url,$comment,$added,$isprivate,$reply\n";
}

function cmp($a, $b)
{
    return strcmp($a[4], $b[4]);
}
?>

No luck. I spill sorts the old way.

 

The comments are just numbers, and I need it to sort them with the highest first.
