怎么实现javascript数组与php数组的地址传递

<&#63;php
$arr = array(3,9,4);
function test($arr){
 $arr[0] = 30;
}
test($arr);
foreach($arr as $val){
 echo $val." ";
}
&#63;>
<script language="javascript" type="text/javascript">
var myarr = [343,90,28];
function abc(arr){
 arr[0]=35;
}
abc(myarr);
document.writeln(myarr[0]);
</script>
