将数据从数据库中提取到php数组中
问题描述：
I've created an array of categories in php like this:
$cats=array("Coffee", "Beverages", "Drinks", "Snacks/Desserts");
But I want to make it like dynamic. Let's say when I update my database via my website (delete-change name-add a new category), I need this array to follow those updates.
Is is possible? Or else, how can I deal with it?
我在php中创建了一个类别数组，如下所示： p>
$ cats = array（“Coffee”，“Beverages”，“Drinks”，“Snacks / Desserts”）;
code> pre>
但我想要它 喜欢动态。 假设当我通过我的网站更新我的数据库时（删除 - 更改名称 - 添加一个新类别），我需要这个数组来跟踪这些更新。 p>
可能吗？ 否则，我该如何处理呢？ p>

答
You can indeed, just use array_push() !
http://php.net/manual/en/function.array-push.php
It pushes your passed variables to the end of the Array, and it increases its size.
答
No. Array can not follow your updates. But you can create the array based on database content. Which is usually what all sites do.
