codeigniter - 在执行foreach时获取当前数组位置$ object-> result_array（） [英] codeigniter - get current array position while doing foreach $object->result_array()

问题描述

在执行foreach时获取当前数组位置指针$ object-> result_array（）

get current array position pointer while doing foreach $object->result_array()

您好，
考虑这个情况。

Hi, consider this, a case.

foreach($object->result_array() as $rs)
{
    //how do i display the current array element index that is the iteration index.
    //i want to call a function when the iterator is in the last-1 position.
    // and more specifically i want to use it in this place and not any other for(;;) loops.
    // and even it is an example with other loops then that is fine.
}

应该有一个选项或使用current
我试过，但仍然需要做一些分析...
而不是调试和跟踪数组元素我发布此线程。

There should be an option or by using current() function. I had tried but still i have to do some analysis… Instead of debugging and tracing the array elements i am posting this thread.

最重要的是可以使用for循环吗？

推荐答案

添加 => $ key 这样也可以获取密钥：

Add => $key like this to get key as well:

foreach($object->result_array() as $rs => $key)
{
   echo $key;
}

with a for循环？

and above all is it possible to do it with a for loop?

是这样：

for($i = 0; $i < count($object->result_array()); $i++)
{
  // your code...
}
