PHP multiple array elements

[Exploded Fiber]

Im not sure the correct syntax to solve this problem.

I have 3 arrays:

A=(3, 4, 5)
B=(1, 3, 5)
C=(5, 3, 2)

I'd like to loop through first element of each array and find the largest int, move to the 2nd element of each array and again find the largest and so forth.

Any suggestions would be apreciated.

<?php
function sort($arr)
{
	for($i=0;$i<count($arr);$i++)
	{
		if($arr[$i]>$arr[$i+1])
		{
			$max=$arr[$i+1];
			$arr[$i+1]=$arr[$i];
			$arr[$i]=$max;						
		}
	}
	return ($arr);
}

$a[0]=3;
$a[1]=4;
$a[2]=5;

$b[0]=1;
$b[1]=3;
$b[2]=5;

$c[0]=5;
$c[1]=3;
$c[2]=2;

$a=sort($a);
$b=sort($b);
$c=sort($c);

?>
