判断$_post的值
1.$_post的值如何判断?

if(isset($_POST["username"])=""){echo"kong";}elseif(isset($_POST["username"])!="admin"){echo"kong";}


上面的写法对吗?
------解决思路----------------------
if(isset($_POST["username"]) && $_POST["username"] == '') {<br />  echo"kong";<br />}elseif(isset($_POST["username"]) && $_POST["username"] != "admin") {<br />  echo"kong";<br />}

------解决思路----------------------
<br />if (isset($_POST['username']) && (empty($_POST['username']) <br><font color='#FF8000'>------解决思路----------------------</font><br> $_POST['username'] !== 'admin')) {<br />    echo 'kong';//空或不等于admin<br />} elseif (isset($_POST['username']) && $_POST["username"] == 'admin') {<br />    echo "yes";//管理员<br />}<br /><br />
