一代码

conn.php

<?php     $conn=mysql_connect("localhost","root","root") or die("数据库连接失败".mysql_error());     mysql_select_db("db_database27",$conn) or die("数据库连接失败".mysql_error());     mysql_query("set names gb2312");?>

index.php

searchrst.php

<?phpheader('Content-type: text/html;charset=GB2312'); //指定发送数据的编码格式include_once 'conn/conn.php';//连接数据库$user =iconv('UTF-8','gb2312',$_POST['users']);//获取Ajax传递的值,并实现字符编码转换$number = iconv('UTF-8','gb2312',$_POST['numbers']);//获取Ajax传递的值,并实现字符编码转换$explains = iconv('UTF-8','gb2312',$_POST['explaines']);//获取Ajax传递的值,并实现字符编码转换$sql="insert into tb_administrator(user,number,explains)values('$user','$number','$explains')";$result=mysql_query($sql,$conn);//执行添加语句if($result){$sqles="select * from tb_administrator ";$results=mysql_query($sqles,$conn);echo "<table width='500' border='1' cellpadding='1' cellspacing='1' bordercolor='#FFFFCC' bgcolor='#666666'>";echo "<tr><td height='30' align='center' bgcolor='#FFFFFF'>ID</td><td align='center' bgcolor='#FFFFFF'>名称</td><td align='center' bgcolor='#FFFFFF'>编号</td><td align='center' bgcolor='#FFFFFF'>描述</td></tr>";while($myrow=mysql_fetch_array($results)){ //循环输出查询结果 echo "<tr><td height='22' bgcolor='#FFFFFF'>".$myrow[id]."</td>";  echo "<td bgcolor='#FFFFFF'>".$myrow[user]."</td>";echo "<td bgcolor='#FFFFFF'>".$myrow[number]."</td>";echo "<td bgcolor='#FFFFFF'>".$myrow[explains]."</td>";echo "</tr>";}echo "</table>";  }?>
