站点出错了 Warning: array_sum() [function.array-sum]: The argument should be an array

Question

程序之前应该是php4 现在服务器上php5出错了​Warning: array_sum() [function.array-sum]: The argument should be an array ​
大概知道是array_sum这函数出了问题，但现在不知道怎么改
​错误代码如下$ds_y = double_format(array_sum($arr_ds['y']));
$ds_s = double_format(array_sum($arr_ds['s']));
$ds_qx = double_format(array_sum($arr_ds['qx']));
$cg_y = double_format(array_sum($arr_cg['y']));
$cg_s = double_format(array_sum($arr_cg['s']));
$cg_qx = double_format(array_sum($arr_cg['qx']));
​​请哪位好心的朋友教教，我是新人，对php只有基本上的了解，编辑方面基本为零 这个怎么改才能正常呢

Answer 1

<?php
}

$ds_y = double_format(array_sum($arr_ds['y']));
$ds_s = double_format(array_sum($arr_ds['s']));
$ds_qx = double_format(array_sum($arr_ds['qx']));
$cg_y = double_format(array_sum($arr_cg['y']));
$cg_s = double_format(array_sum($arr_cg['s']));
$cg_qx = double_format(array_sum($arr_cg['qx']));
$ck = double_format(array_sum($arr_ck));
$hk = double_format(array_sum($arr_hk));
$qk = double_format(array_sum($arr_qk));
$yk = double_format($ds_y-$ds_s+$cg_y-$cg_s+$cp_win_z+$lotto_z);
?>

Answer 2

打印下$arr_ds和$arr_cg

Answer 3

Warning: array_sum() [function.array-sum]: The argument should be an array ​
array_sum 的参数应该是一个数组

Answer 4

在你贴出的代码前，加上这个
echo "<pre>";
print_r($arr_ds);
print_r($arr_cg);
exit;

Answer 5

恩，但是这我要怎么修改才可以呢
结果出来了Array
(
)
Array
(
)
 
接下来我怎么修改呢

Answer 6

你提示这个错误码？ Notice: Undefined index: y 

Answer 7

加一步判断比如array_sum(is_array($arr_ds['y'])?$arr_ds['y']:array());
不行你就用if

Answer 8

if语句怎么改啊，我刚刚用你这个方式改过后还是出错Parse error: parse error, unexpected ';'

Answer 9

没一个外面都加
if(!empty($arr_ds['y'])){
$ds_y = double_format(array_sum($arr_ds['y']));
}

Answer 10

The argument should be an array ​参数必须是数组。就是这个意思。检查出入的参数
