例子： <?php
session_start();
if($_SESSION[user_name]=""){
echo "<a href="index.php">您没有登录,请返回主页登录!</a>";
}else{
echo "<font coler="red">欢迎你:".$user_name.</font>;
echo "<br>";
$id1=mysql_connect("localhost","xxxxx","xxxxx");
mysql_select_db["English",$id1];
$danyuan1=$_POST["danyuan1"];
$nianji1=$_POST["nianji1"];
$aa99="select*from danci where nianji='$nianji1' and danyuan='$danyuan1' AND id='$umb1'";
$result=mysql_query($aa99,$id1);
$info1=mysql_fetch_array($result,MYSQL_ASSOC);
echo "<img src="images/english/004.jpg">";
echo "<br><br>";
echo "<font color="blue" size="5">本单词为"

不要怪我说的难听，你的基本功是我见过最差的。调用函数居然会方括号！
希望你系统学习一下，必将对你有帮助。磨刀不误砍柴工
请对比我的代码，看有哪些改动。希望对你有一丝丝的帮助
