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.

推荐答案

如果你真的只想打印它们，你可以这样做:

If you really just want to print them, you could do something like:

print_r($_POST);

或者，您可以通过以下方式与他们单独互动:

Alternatively, you could interact with them individually doing something like:

foreach ($_POST as $key => $value) {
    //do something
    echo $key . ' has the value of ' . $value;
}

但无论你做什么......请过滤输入.SQL 注入让每个人彻夜难眠.

but whatever you do.. please filter the input. SQL Injection gives everyone sleepless nights.
