创建无按键阵列在一个循环 [英] Creating an array without keys in a loop
问题描述
这可能是一个大脑放屁,因为它是一个晚一天,但我在这里卡住了。
This might be a brain fart, since it's a late day, but I'm stuck here.
我需要从一个选择框取$ _ POST值。 (这是一个数组),并将其转换为一个简单的阵列不具有任何密钥。
I need to take a $_POST value from a select box. (It's an array), and convert it to a simple array that doesn't have any keys.
下面是从项目的print_r:
Here's the print_r from the item:
阵列([0] => 19 [1] => 18 [2] => 21)
问题是,我需要一个数组,看起来像这样:
Problem is, I need an array that looks like this:
阵列(19,18,21)
每当我试图通过表单域的foreach(),我必须做这样的事情:
Whenever I try to foreach() through the form field, I have to do something like this:
$行[] = $ VAL;
但是,这给我留下了一个数字索引。
But that leaves me with a numerical index.
我是什么失踪?
感谢。
推荐答案
您不能没有密钥的阵列。
you can't have an array without keys.
Array(19,18,21)
该数组有键0,1和2。
this array has keys 0,1 and 2.
