Need to sort this multi-dimensional array!

[The_Tim]

I have this function to make my $members array..

	function members()
	{
		$members_file = './site_data/members.txt';
		$fp = fopen($members_file, 'r');
		$members_list = fread($fp, filesize($members_file));
		$members_list = explode("\n", $members_list);

	for( $i = 0; $i < count($members_list); $i++ )
	{
		$member = preg_split("/\|/", $members_list[$i]);
		$members[$i]['nick'] = $member[0];
		$members[$i]['name'] = $member[1];
		$members[$i]['age'] = $member[2];
		$members[$i]['country'] = $member[3];
		$members[$i]['fav_map'] = $member[4];
		$members[$i]['fav_civ'] = $member[5];
	}

	return $members;
}

I need to sort this array by the 'nick' column .. I'm not very familiar with writing usort functions, so if someone could help me out I'd appreciate it!

It looks like you would create your own compare function, and sort by that....maybe something like this

//outside of loop 
function cmp($a, $b)
// When sorting a multi-dimensional array,
//$a and $b contain references to the first index of the array.
{
   return strcmp($a["nick"], $b["nick"]);
}


//in your function

return usort($members, "cmp");

bah just barely beat me :p

anyways I would suggest using single quotes since those are all static strings, save you some process time since PHP wont have to try and evaluate them then...

$a['nick'] and 'cmp'... etc

mtimdog:

I've tryed this method, here's a list of the members it must sort:

_TimZilla
InFlaMeZilla
DamrightZilla
ZealZilla
bvirusZilla__
P1nkSkirtZilla
GizerZilla

---

using your method this is how it sorts:

TimZilla
GizerZilla
bvirusZilla__
DamrightZilla
InFlaMeZilla
P1nkSkirtZilla
ZealZilla

i'm confused 🙂

[tekky]

function cmp($a, $b)
{
   return strcmp(strtolower($a['nick']), strtolower($b['nick']));
}

the strtolowers() will make ALL letters evaluate equally so A would equal a etc....

that should fix the problem

omg lol... maybe i should get some sleep .. i should have thought of that one 😉

thanks !

hehe, no biggie, I only knew because I had to use usort() a while back in a similiar situation and it jacked up just like that due to the caps and lowercase 😉

glad it works
