php向java函数传递二维数组参数时遇到的问题

hjxisking

<?php
$api = new Java("…….……");
for($i=0;$i<8;$i++)
{
        $arry[$i]=array_pad(array(),5,'a');
}
$ret = $api->list_svc($arry);
echo "return:".$ret."<br>";
echo "status:".$arry[0][4]."<br>";
?>

我的想法是向我的list_svc这个java函数传递一个二维的数组，然后在list_svc函数中会填充传进来的数组，同时返回一个return值。
现在我的返回值正确，可是数组似乎没有被填充，输出$arry[0][4]得到的结果还是预先定义的a字符，这是为什么？
难道传参数的时候要$api->list_svc(&$arry);？但还是没用！！
求各位帮忙告知一下，我错在哪里，该怎么做？

我知道这是由于php是通过传值来实现的，只有在定义方法的时候在方法的形参前加引用“&”，所以现在我修改了我java的api接口，让函数直接返回一个二维数组给php，现在问题又来了，页面有时显示正确有是不正确，错误提示一会是NullPointException一会是找不到我那个java的Class里的list_svc方法，我用命令行的方式直接执行，发现是java虚拟机有段错，以下是我的错误log，大家帮忙看看。
