$_REQUEST, $_GET 和 $_POST 哪个最快? [英] Among $_REQUEST, $_GET and $_POST which one is the fastest?

问题描述

这些代码中哪个会更快?

Which of these code will be faster?

$temp = $_REQUEST['s'];

或

if (isset($_GET['s'])) {
  $temp = $_GET['s'];
}
else {
  $temp = $_POST['s'];
}

推荐答案

$_REQUEST，默认包含$_GET、$_POST和$_COOKIE的内容.

但这只是一个默认值，这取决于variables_order ;并且不确定是否要使用 cookie.

But it's only a default, which depends on variables_order ; and not sure you want to work with cookies.

如果非要我选，我可能不会用$_REQUEST，我会选择$_GET 或$_POST -- 取决于我的应用程序应该做什么 (即一个或另一个，但不是两个):一般来说:

If I had to choose, I would probably not use $_REQUEST, and I would choose $_GET or $_POST -- depending on what my application should do (i.e. one or the other, but not both) : generally speaking :

• 当有人从您的应用请求数据时，您应该使用$_GET.
• 当有人将(插入或更新；或删除)数据推送到您的应用程序时，您应该使用$_POST.

• You should use $_GET when someone is requesting data from your application.
• And you should use $_POST when someone is pushing (inserting or updating ; or deleting) data to your application.

无论哪种方式，性能都不会有太大差异:与脚本的其余部分相比，差异可以忽略不计.

Either way, there will not be much of a difference about performances : the difference will be negligible, compared to what the rest of your script will do.
