PHP code

<?
//1. 声明字符编码
header("Content-Type:text/html;charset=utf8"); 
 
//2. 连接数据库
$link=mysql_connect("localhost","root","root");//连接数据库
if(!$link) echo "系统异常,请稍后再试";//如果连接数据库失败
mysql_select_db("test", $link); //选择数据库
mysql_query("set names &#39;utf8&#39;");  // 解决中文乱码
 
//3. 获取数据
$name = $_POST["name"];
$phone = $_POST["mobile"];
$score=$_POST["score"];
 
//4. 查询手机号码是否存
$strsql = "select phoneNumber from user_info where phoneNumber=&#39;$phone&#39;";
mysql_query("SET NAMES utf8");
$result=@mysql_query($strsql);//执行查询
$row=mysql_fetch_array($result);//获取数据行
 
//5. 根据是否返回数据行,如果数据行为空,即已参与活动,否则返回获得奖励等级
if(!empty($row)){
    //5.1 数据行不为空,返回0
    echo 0;
}else{
    //5.2 数据行为空,手机号码没有参与活动,插入数据到数据库
    $strsql = "insert into user_info(userId,userName,phoneNumber,userScore,dataTime) values(null,&#39;$name&#39;,&#39;$phone&#39;,&#39;$score&#39;,now())";
    $result = @mysql_query($strsql);
    
    //5.3. 成功添加
    if($result)
    {
        if($score>=100) echo "一等奖";
        if($score<100&&$score>=60) echo "二等奖";
