PHP中的错误，内爆-[内部]，行？

好的，让我从一开始就开始，我是一个新手，正在处理一个用cakephp 1.2编码的发票示例，并试图让它工作，但我使用的是cakephp 2.1和php 5。？？这意味着一些代码与原来的代码不同，我正在努力找出它们，因为我一直在看这个错误3天，但没有找到任何地方，这就是为什么我要发送求救信号：）

私有方法 读了这里之后，我得到了一个错误操作数错误，这是因为我试图用一个字符串进行乘法和数组，或者这就是我想的，所以我将它改为下面的函数

# returns line item qty times price
function __lineItemTotal($qty, $price)
{
    
$arrayjoin = array_merge((array)$qty, (array)$price);
    return array_product($arrayjoin);
    settype($arrayjoin, "integer");
    print_r($arrayjoin);

}

现在我得到了另一个错误，当有一个十进制数作为价格选择，下面是通知代码和上下文

(int) 5 => ''Service'',
(int) 6 => '49'
)
$fieldInsert = array(
(int) 0 => '`unit_id`',
(int) 1 => '`qty`',
(int) 2 => '`description`',
(int) 3 => '`price`',
(int) 4 => '`total`',
(int) 5 => '`name`',
(int) 6 => '`invoice_id`'
 )

 }

在看了几周之后，我发现保存mysql就是试图保存一个数组，这个集合在哪里

 Code:
 $valueInsert = array(
 (int) 0 => '1',
 (int) 1 => array(
 (int) 0 => '55.00'
 ),
 (int) 2 => array(
 (int) 0 => '' testing =\"testing \"''
  ),
   (int) 3 => array(
 (int) 0 => '10.01'
 ),
 (int) 4 => '550.55',
 (int) 5 => ''Service'',
 (int) 6 => '49'
 )

谢谢大家，希望能解决这个问题

干杯

该错误可能是由

\u list

函数中的一个

find

调用引起的。你有没有一个接一个地试过这些电话，看看是否有任何一个会触发错误？这可能是因为您正在向

find

方法提供一组无效的参数，然后它尝试使用

内爆来转换这些参数。
