<?php
include 'db.php';//保存数据库信息的
$query="SELECT * FROM word WHERE id='$p'";
$db = mysql_connect($dbserver,$dbid,$dbpassword);//数据库联接
mysql_select_db($dbname,$db);
$p = 2;
$result = mysql_query($query,$db);//sql查找
echo " 1 ";
echo $result;
$myrow = mysql_fetch_row($result);//存入数组
echo " 2 ";
echo $myrow;
echo " 3 ";
printf("%s",$myrow[1]);//输出标题
echo "<br/>";
?>
myrow[1]是text型的
