I have an array that looks like

$array = Array(
        Array($var1, $var2, $var3),
        Array($var1, $var2, $var3),
        Array($var1, $var2, $var3)

I want to sort the arrays within $array by $var3 (although if it helps i can 
easily change that to $var1). $var1 and $var2 are strings, $var3 is a number 
(in form of ([0-9]{3}\.[0-9]) )

I know i could put something together that would make a new, 
single-dimensional array that looks like Array(var3, var3, var3...), sort 
that, then use that as a reference point, but that's a really sloppy 
approach, and I'm thinking probably not the best way.

I have a feeling someone is just going to reply with only 
"php.net/somefunction" in the body of their message, and I'll feel stupid, 
but oh well. I can't find anything in the man.

Any input would be appreciated.
