note 102580 added to function.array-diff

A function to find values that only occur
once in a number of arrays.
I still need one to allow any amount of input arrays, so if anyone knows, please let me know.

This is my function to find all the unique values:

<?php
function array_uniquevalues($array1,$array2,$array3)
{
$trvalues[]=array_merge(
array_intersect($array1,$array2),array_intersect($array2,$array1)
);
$trvalues[]=array_merge(
array_intersect($array2,$array3),array_intersect($array3,$array2)
);
$trvalues[]=array_merge(
array_intersect($array1,$array3),array_intersect($array3,$array1)
);
$trvalues=array_unique(
array_merge($trvalues[0],$trvalues[1],$trvalues[2])
);
$tvalues=array_unique(
array_merge($array1,$array2,$array3)
);
$rvalues=array_diff($tvalues,$trvalues);
$rvalues=array_values($rvalues);
return $rvalues;		
}
	
$array1 = array('red','green','blue');
$array2 = array('red','yellow','green');
$array3 = array('pink','yellow','red');
print_re(array_uniquevalues($array1,$array2,$array3));
?>

result:
Array
(
        [0]=>blue
        [1]=>pink
)
