How to grab all variables in a post (PHP)?
I don't want to deal with $_POST['var1']; $_POST['var2']; $_POST['var3']; ...I want to echo all of them in one shot.

If you really just want to print them, you could do something like:
如果您真的只想打印它们，您可以执行以下操作：
print_r($_POST);
Alternatively, you could interact with them individually doing something like:
或者，您可以通过以下方式与他们单独互动：
foreach ($_POST as $key => $value) {
//do something
echo $key . ' has the value of ' . $value;
}
but whatever you do.. please filter the input. SQL Injection gives everyone sleepless nights.
但无论你做什么.. 请过滤输入。SQL 注入让每个人彻夜难眠。

If you want the POST values as variables in your script, you can use the extract function, e.g.
如果您希望 POST 值作为脚本中的变量，您可以使用提取函数，例如
extract ( $_GET );
or
或者
extract ( $_GET, EXTR_IF_EXISTS );
There are several flags you can use (check the manual); this one restricts extraction to variables already defined.
您可以使用几个标志（查看手册）；这将提取限制为已定义的变量。
You can also use the import_request_variables function.
您还可以使用 import_request_variables 函数。
