我是PHP的初学者，在phpdesigner上进行编程，看的是W3shcool上的教程,按教程
做的方法做了一遍，发现得不到想要结果，提交后得不到想要的值
<html>
<head>
<title >test</title>
</head>
<body>
<?php
$zhanghao = $mima = "";
if (!empty($_SERVER["REQUEST_METHOD"])) {
$zhanghao = test_input($_POST["zhanghao"]);
$mima = test_input($_POST["mima"]);
echo $REQUEST_METHOD;
echo $zhanghao;
echo $mima;
} else {
echo "111";
}
?>
<div id="denglu">
<form method="post" action="<?php $_SERVER["PHP_SELF"]; ?>" >
账号：<input type="text" name="zhanghao" form="user_form" value="<?php echo
$zhanghao; ?>" />
<br />
密码：<input type="text" name="mima" form="user_form" value="<?php echo
$mima; ?>" />
<input type="submit" value="Submit" />
</form>
</div>
</body>
