I have a set of arrays that looks like this:

$array[1][1]==int
$array[1][2]=="a string"
$array[1][3]=="a string"

$array[2][1]==int
$array[2][2]=="a string"
$array[2][3]=="a string"

$array[3][1]==int
$array[3][2]=="a string"
$array[3][3]=="a string"

$array[4][1]==int
$array[4][2]=="a string"
$array[4][3]=="a string"

$array[5][1]==int
$array[5][2]=="a string"
$array[5][3]=="a string"

and so on until the first dimension reaches 10000. I'm trying to sort $array by int so that $array[1][1] is greater than $array[2][1]. I don't want the strings compared at all; they must stay attached to their int. For example:

$array[1][1]==5052
$array[1][2]=="this is a string attached to 5052!"
$array[1][3]=="this is another string attached to 5052!"

$array[2][1]==1000
$array[2][2]=="this is a string attached to 1000!"
$array[2][3]=="this is another string attached to 1000!"

$array[3][1]==10500
$array[3][2]=="this is a string attached to 10500!"
$array[3][3]=="this is another string attached to 10500!"

$array[4][1]==2000
$array[4][2]=="this is a string attached to 2000!"
$array[4][3]=="this is another string attached to 2000!"

$array[5][1]==2101
$array[5][2]=="this is a string attached to 2101!"
$array[5][3]=="this is another string attached to 2101!"

would become...

$array[1][1]==10500
$array[1][2]=="this is a string attached to 10500!"
$array[1][3]=="this is another string attached to 10500!"

$array[2][1]==5052
$array[2][2]=="this is a string attached to 5052!"
$array[2][3]=="this is another string attached to 5052!"


$array[3][1]==2101
$array[3][2]=="this is a string attached to 2101!"
$array[3][3]=="this is another string attached to 2101!"

$array[4][1]==2000
$array[4][2]=="this is a string attached to 2000!"
$array[4][3]=="this is another string attached to 2000!"

$array[5][1]==1000
$array[5][2]=="this is a string attached to 1000!"
$array[5][3]=="this is another string attached to 1000!"

however I have no idea how to do this. I tried looking at array_multisort, but the article pretty much lost me. can anyone help?

That looks suspiciously like a homework assignment!

LOL. How do people keep finding these old posts? Froth hasn't been here since posting the question (don't you love how people pepper all the available forums with their question and never show up again to see the answer?), and the URL isn't working.

Lol! The reason he hasn't checked it is probably because he has no time management skills.
