Sorting a multidimensional array

[iPixel]

Hey guys, quick question.

 

I have an array that looks like (blow). How can i sort it based on array[0][3], the #'s 1,2,3,4,5,6 are what i want to sort by in ASC order.

 

<?php

Array ( 
	[0] => Array ( 
			[1] => Link Name 
			[2] => URL
			[3] => 1 
			[4] => fy 
	) 
	[1] => Array ( 
			[1] => Link Name 
			[2] => URL
			[3] => 2 
			[4] => fy 
	) 
	[2] => Array ( 
			[1] => Link Name 
			[2] => URL
			[3] => 3 
			[4] => fy 
	) 
	[3] => Array ( 
			[1] => Link Name 
			[2] => URL
			[3] => 4 
			[4] => fy 
	) 
	[4] => Array ( 
			[1] => Link Name 
			[2] => URL
			[3] => 5 
			[4] => fy 
	) 
	[5] => Array ( 
			[1] => Link Name 
			[2] => URL
			[3] => 6 
			[4] => fy 
	)

?>

 

Thanks for the help.

Use usort() with a function that compares that index.

[iPixel]

so something kind of like usort(array, function)

 

and the function would look like...

 

function ()
{
      if(array[0][3] < array[1][3])
        { return something }
}

I think i got it, seems to be working.

 

<?php
function cmp($a, $b)
{
    if ($a[3] == $b[3]) {
        return 0;
    }
    return ($a[3] < $b[3]) ? -1 : 1;
}

usort($show, "cmp");
?>
