<?php
$array1=array('0'=>array('0'=>1,'1'=>2,'2'=>3),'1'=>array('0'=>4,'1'=>5,'2'=>6),
'2'=>array('0'=>7,'1'=>8,'2'=>9));
$array2=array('0'=>array('0'=>2,'1'=>4,'2'=>8),'1'=>array('0'=>3,'1'=>6,'2'=>9),
'2'=>array('0'=>4,'1'=>8,'2'=>12));

$result=array();
$x=0;
while($x<=2)
{
	for($y=0;$y<=2;$y++)
	{
		$result[$x][$y]=$array1[$x][$y]-$array2[$x][$y];
		
	}
	$x++;
}
	echo "<pre>";
	echo "matrix"." ";
	print_r($result);
	

?>
