echo $_POST["name"]; //returns the value a user typed into the "name" field

我希望能够返回密钥的文本。在这个例子中，我想返回文本“name”。我可以这样做吗？

Answer 1

$ _ POST只是一个普通的关联数组，所以你也可以循环遍历整个事情：

foreach($_POST as $key=>$value)
{
  echo "$key=$value";
}

检查array_keys（）函数，假设这是PHP。

Answer 6

foreach($_POST as $rvar)
{
 $rvarkey=key($_POST)
 $$rvarkey=mysql_real_escape_string($rvar);
}

it creates variables having the name of the request parameters which is pretty awesome.
