How do I get the key values from $_POST?
提问by Haabda
echo $_POST["name"]; //returns the value a user typed into the "name" field
I would like to be able to also return the text of the key. In this example, I want to return the text "name". Can I do this?
我也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？

Check out the array_keys() function assuming this is PHP.
假设这是 PHP，请查看 array_keys() 函数。

$_POST is just a normal associative array so you can also loop over the entire thing like this:
$_POST 只是一个普通的关联数组，所以你也可以像这样循环整个事情：
foreach($_POST as $key=>$value)
{
echo "$key=$value";
}

@Tim: there was a )missing. so it should be:
@Tim：有一个)失踪。所以应该是：
while( list( $field, $value ) = each( $_POST )) {
echo "<p>" . $field . " = " . $value . "</p>\n";
}

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.
