如何在帖子中抓取所有变量（PHP） [英] How to grab all variables in a post (PHP)

问题描述

如何在帖子中抓取所有变量（PHP）？
我不想处理 $ _ POST ['var1']; $ _POST [ VAR2’ ]; $ _POST [ VAR3’ ]; ...
我想一次回显所有内容。 如果你真的只是想打印它们，你可以这样做：

  print_r（$ _ POST）; 
  

或者，您可以单独与它们进行交互，例如：

  foreach（$ _POST as $ key => $ value）{
 //做某事
 echo $ key。 '具有'的价值。 $值; 
} 
  

但是无论您做什么，请过滤输入。 SQL注入给每个人不眠之夜。

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.

解决方案

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

print_r($_POST);

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

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.
