Call Function With Array 2 Dimension

[Anon]

I create Fuction to build graph but I can't send value in $array[$x][$y] example below
EX.
$m=0
For($i=0;$i<30;$i++) {
$j=0;
$grx[$j][$i]=$m;
$gry[$j][$i]=0;
$m++;
}
function line($g,$h,$grx,$gry);
Can I use 2 array dimension for function?...
thank you for your answer...:-)

i don't see why it wouldn't work...

are you getting an error message, or is it merely behaving oddly?
