iterative function

基本解释

In this case (outlined in following code example) the cargo is just a number that keeps getting fed back into an iterative function.
在本例中（在以下代码示例中概述），cargo 只是不断将反馈传送给迭代函数的一个数字。
There is an addition to this listing that wasn't in Listing 1: You're now taking full advantage of odbc_fetch_row() being an iterative function by placing it within a while loop.
该清单在清单 1的基础上添加了一些内容：现在可以完全将 odbc_fetch_row() 函数用作迭代函数，只需将它放在 while 循环中即可。
This is an iterative function, meaning that if you call it again, you'll get the next result in the set (and so on, until there are no results in the result set, in which case, it will return false).
这是一个迭代函数，这意味着如果您再次调用它，会得到结果集中的下一个结果（依此类推，直到结果集中没有结果，如果没有结果，则返回 false）。
